    The camera car in these two videos is the Burger Tuning F10 M5. This car has a BMS JB4 piggyback and downpipes. Some impressive output at the wheels has been shown from this car on a Dynojet in the in the ~630 wheel horsepower range. That is a tall order to overcome for a 335i even for one equipped with upgraded twin turbos. The 335i just is giving up too much power and torque to the M5 along with quicker shifts to the DCT. And the DCT is the key. The first video shows an E92 335i that has a manual transmission and it gets crushed. The second video has a similarly modded E92 335is with the RB turbo upgrades but the difference is that it is the 335is model that has the DCT transmission. Look at the results and see what a difference a dual clutch makes for yourself.

    BMW had the new 2015 F82 M4 out in Long Beach, California for the Grand Prix last weekend. Fortunately, someone was able to record the startup and exhaust note sounds along with a few revs. The engine noise is not exactly what we have come to expect from BMW M. You be the judge but this is not the best sounding inline-6 engine that the M division has ever produced, that much is certain. One of the onlookers yells 'Sounds like my Prius' which may be the best assessment yet.

    This W204 C63 AMG belongs to BenzBoost member charliekay. He took his car to the same drag strip when tuned both when naturally aspirated and when supercharged. Previously, he ran 11.8 @ 119 when naturally aspirated with an OE Tuning tune. With the addition of the Weistec Stage II 2.3 liter twin screw supercharger his elapsed time improved to 11.1 and his trap speed increased by eight miles per hour to 127.33. That is a solid difference right there especially considering the forced induction run was in warmer weather. @charliekay's full impressions below: Hello all, Last night I finally got around to running the car, after a couple of busy months. Very impressed with the times, and gain overs the N/A setup. The car has the following: - 2008 C63 with Original Tranny - Weistec Stage II Supercharger w/ Oil/Air Seperator - OEM multispoke 19s on front, w/ OEM Conti tyres - OEM 5-spoke 18s on rear, w/ MT ET Streets 265/40 - Full interior with no weight reduction - Pump Fuel - 98RON (equivalent to 93R+M/2) - I only ever use BP Ultimate 98 - iPE Full Valvetronic Exhaust N/A the fastest the car ran was 11.803, this was with the iPE Exhaust and OE Tuning Stage II tune. Unfortunately I cannot find the timeslip for the 11.80 run, but I have one for an 11.83 run I did, which was 1.849 60ft, and trap speed was 119mph For comparison reasons, I used the same car, same wheels (including rubber), same fuel, same track (Sydney Dragway), same exhaust, all with full weight. Obviously it was a different day so different temp, looking at the different time slips, looks like there was a 10 degree Celsius temperature difference between the runs, last night being hotter. Not sure how much time this equates to, but just trying to be 100% clear with the results. So last night after the Stage II was put on, I ran 11,205, 11.181, 11.184, 11.184 again and the last run was the fastest being 11.162. This mean the Weistec charger took a minimum of 6.5/10ths off the N/A time. The reason I say minimum is traction is a problem with that much power, you can feel the car hesitates and jumps a little when it hits second. I think some 16s or 17s with better rubber would be worth 1-2/10ths just in solving the jump into second, not to mention the gains in weight reduction and 60ft gains. Anyways here is the time slip.

    So you know those people who say meth is bad? No not high school guidance counselors those people on automotive forums who try to scare you away from methanol injection. Try to argue methanol is bad when the results you are about to see show the BMW S63TU 4.4 liter direct injected twin turbo V8 loving the stuff. The octane benefit can not be denied and the reality is a proper meth system with failsafes makes for a motor that resists detonation to a greater degree than it would on pump gas making it safer. What does methanol do for the F10 M5 and S63TU? Oh, it just bumps the output to 678 wheel horsepower on a Dynojet in STD correction. Torque goes to 641 lb-ft at the wheels. The 678 peak wheel horsepower figure comes with a 628 peak lb-ft of torque reading. Regardless, compare these results to what was achieved without methanol injection. The octane bump is allowing a timing increase that increases output by roughly ~40 wheel horsepower. Peak torque does not increase by much although the area under the curve and the top end definitely does. Meth is good for you.

    Wow, Mercedes is flat out flying out of the gate in 2014. Another Grand Prix and another 1-2 finish this time in Bahrain. McLaren states they can catch Mercedes but clearly everyone is scrambling to come up with a solution. Here is what McLaren racing director Eric Boullier had to say, "It’s true that the gap is huge now, but a one-second gap is catchable. I know a lot of areas we can work on and improve, so I think they can definitely be caught. We are aggressively developing now to make sure we can catch up with them." When your competition says the gap is huge and they are aggressively trying to catch up to you then you know you are doing things right. As if being first place in the standings and winning the first three races of the year was not proof enough. Mercedes is way out in front in the standings but obviously this is very early. At the Bahrain GP Lewis Hamilton took the victory followed by Nico Rosberg. Rosberg is 11 points ahead of Hamilton for first place in the standings. It will be interesting to see how the team treats the two as they both compete for the championship. Hopefully they are both able to battle with each other as well (as they did in this race) so that a championship does not come down to politics. Regarding the quality of the racing itself the Grand Prix was exciting. Rosberg and Hamilton started from the front of the grid and both went back and forth from the beginning. They both were essentially told to cool it off towards the end but seeing them go head to head bodes well for the competitive aspect from the team. Rosberg stated it was the best battle of his career and Hamilton said it was the hardest race he had ever won. What about everyone else? Clearly Mercedes is on another level right now with everyone else chasing them. Ferrari's Fernando Alonso managed a respectable fourth place finish. Red Bull Racing finished in 6th and 10th with Sebastian Vettel ahead of teammate Daniel Ricciardo. McLaren picked up 5th and 7th place finishes. The full standings are below. Things are looking great for Mercedes heading into the fourth race of the year in China taking place next weekend. Will Mercedes keep up this pace? Will the other teams catch them? It is going to be interesting to watch and the 2014 season is not disappointing.

    Remember those rumors from last year that BMW would follow Honda back to Formula 1? There is some substance to them. Now, this would not be a complete return but BMW would be back as an engine supplier. This would be a big deal in the new Formula 1 turbocharged era considering the last time BMW built Formula 1 turbocharged motors the engines dominated and produced power to such a degree that they were banned. BMW's performance image has taken a huge tumble to say the least. A return to Formula 1 in any capacity would be good for the brand. Not to mention, BMW still is capable of building the best engines in the world despite the fact they have not shown this capability in quite some time. They still have it, don't they? Well, Formula 1 would certainly put their engineering to the test. BMW's board of directors will meet next month to evaluate whether BMW should return to supplying motors for F1 competition or not. Who knows what their decision will be. Will BMW show some pride and compete at the highest levels? Will BMW's board instead decide top level competition is 'too expensive' and hide their tail between their front wheel drive Active Tourer's tires? We will have to wait and see. Source

    Mercedes-Benz, you are on quite the roll! You know by now that a new sports car is coming from Mercedes-Benz which will likely be called the AMG GT. The latest round of spyphotos gave us a decent idea of what the exterior proportions and design will be but they did not display any interior details. We now have those interior details thanks to a internet leak of the photos of the official finished interior design and it is simply stunning. The stitching, the two tone leather, the integrated infotainment system, the round vents, progressive center console design, etc., all gorgeous. This vehicle is shaping up nicely and with some big output expected out of the M177/M178 4.0 liter twin turbo V8 the AMG GT is going to be a very solid all around luxury sports car. Hopefully the next leak is of the finished exterior.

    So in the GTR world what is 'fast' now is a 7 second run at over 180 miles per hour. Absolutely mind blowing performance. Congratulations to ETS (Extreme Turbo Systems) who deserves all the credit in the world for raising the already absurdly high GTR bar. The car is trapping 146 in the 1/8 mile. 146 is stupid fast for a car in the 1/4 let alone the 1/8. And boy is it hooking up! A 1.296 60 foot. The only words for this are abbreviated WTF. This is no fluke either back to back passes both hit 7.8's at 183 miles per hour. Quick, fast, hooks up, and consistent. It's hard to beat. Slips and video below.

    Some good tuning here that shows off the flexibility offered by the plug and play ProEFI 128 ECU for the Porsche 996 Turbo platform. ProEFI offers a kit that is fully ready for the 996 Turbo along with coils, 5 BAR MAP sensor kit, fuel pressure kit, CAN cable, wideband 02 sensors, EGT sensors, E85 flexfuel capability, wiring, essentially the works to make the 996 Turbo play nice with significant engine changes. With some big turbos and internal engine upgrades including forged rods the result is 1010 whp on a Mustang Dyno. The car also was put on a Dynojet but the Dynojet maxed out at 1000 whp. Maxing out a Dynojet? Good times. That particular dynamometer needs an update to show the full figures but clearly the power is verified on more than one dyno. Regarding performance the car traps 152. A best run of 10.253 @ 152.90 shows the capability for deep 9 second performance although the 60 foot of 1.831 needs significant improvement to get there. As this is a rear wheel drive car (preserving the all wheel drive drivetrain becomes more difficult and requires greater investment at these torque levels) it is a bit more difficult to hook up off the line. Better to spin tires than break parts though, right? Solid work all around showing the 996 Turbo as a great Porsche tuning value platform considering what used examples can be picked up for today. Graphs and slips below. Mustang: Dynojet: Timeslips: Pictures:

    Here is a nice teaser from Mercedes-Benz who is attacking BMW everywhere they can. From the high end, to the low end, to enthusiast cars, and across the SUV spectrum. Mercedes-Benz is winning the battle as well (as they deserve too) and this is a new volley in the war. BMW created a hit with the X6 which essentially took the four door coupe idea that Mercedes pioneered to SUV's. Mercedes is now responding with the MLC. This is a concept which will be fully revealed at the upcoming Beijing show but like all recent Mercedes-Benz concepts it is beautiful. The question is, will it be as heavy as the M-Class? Will it be sportier? Will it be more fun to drive? Will the changes be mostly cosmetic in a similar manner of X6 to X5? We will wait and see. Enjoy the preview.

    GM you are definitely starting to change some minds about whether that bailout was a good idea. Say hello to the 625 horsepower and 635 lb-ft of torque 2015 Chevrolet Corvette Z06 drop top. That power and torque comes courtesy of a supercharged 6.2 liter and direct injected LT4 V8. So we know the car has some big balls but how about those looks? The optional Z07 package adds gorgeous aerodynamic enhancements. Not to mention carbon ceramic brakes that save 23 pounds over the standard rotors along with Michelin Pilot Sport Cup tires. Looks AND performance, that's how it is done. GM claims the curb weight is nearly identical to the coupe. How close is 'nearly' in this context? They do not quote an exact figure but let's give the benefit of the doubt that this will be within 100 pounds of the coupe. If so, they did a hell of a job. You also have the choice of a manual or automatic transmission with launch control programs for both. The automatic of course being the super fast 8-speed 8L90 that is getting a ton of attention. Pictures and press release below. Expecting pricing information to come soon but this car is already a hit. Drop-top Supercar: 2015 Corvette Z06 Convertible NEW YORK – Chevrolet today introduced one of the most capable drop-tops on the market: the 2015 Corvette Z06 Convertible. With at least 625 horsepower, and 635 pound-feet of torque, the Z06 is also the most powerful convertible ever produced by Chevrolet. "The Z06 Convertible is a world-class supercar in every sense," said Mark Reuss, executive vice president, Global Product Development. "Only a handful of convertibles in the world bring more than 600 horsepower and 600 pound-feet of torque. Even fewer can match the advanced technologies, aerodynamic design, and visceral driving experience of the Z06 Convertible." This is the first Z06 Convertible offered from the factory since 1963 when the Z06 option package was introduced for endurance racing. Records show only 199 Corvette orders with a Z06 package that year, including one convertible. Recent technological advancements enable the building of a modern Z06 Convertible, said Corvette chief engineer Tadge Juechter "Until recently it was not possible to create a lightweight, open-roof structure strong enough to cope with the braking, cornering, and acceleration of Corvette's top performance models," Juechter said. "The frame for the Z06 convertible leverages advancements in computer-aided engineering, metallurgy, and manufacturing techniques – many of which were not available just five years ago." The aluminum structure is 20 percent stiffer than the previous, fixed-roof Z06. As there are no structural reinforcements needed for the Z06 Convertible, its curb weight is nearly identical to the Z06 Coupe. They also share the same chassis tuning, powertrain output, driver technologies and equipment options – including the Z07 Performance Package, which adds Brembo carbon-ceramic matrix brakes, Michelin Pilot Sport Cup tires and adjustable front- and rear-aerodynamic components. "The most impressive aspect of the Z06 Convertible may be its performance bandwidth," said Juechter. "Very few cars on the market can match its combination of extreme, supercar levels of performance; the flexibility for daily driving and long-distance commuting; and the 360-degree, open-air driving experience only true convertibles can offer." All-aluminum, high-tech foundation The Corvette Z06 Convertible represents the culmination of more than four years developing an all-new, all-aluminum structure for the seventh generation Corvette. That structure, built at General Motors' Bowling Green Assembly plant, was designed to the specifications of the Corvette Stingray, Corvette Z06 and the Corvette Racing C7.R. "We wanted a frame that was lighter than the steel frame of the previous Corvette, yet strong enough for both a 600-horsepower convertible and a 24-hour endurance racer," said Ed Moss, engineering group manager for Corvette structures. "That would not have been possible without improvements in computer-aided engineering software, which allowed us to model more than 17,000 frame iterations, with each iteration improving strength and stiffness, while reducing mass." The team used nearly 186,000 computational hours of modeling to develop the frame. It features main rails composed of five customized aluminum segments, including aluminum extrusions at each end, a center main rail section and hollow-cast nodes at the suspension interface points. The gauge of each segment varies in thickness from 2mm to 11mm, tailored – along with the shape – to meet the strength and stiffness requirements for each frame section with minimal weight. These components are assembled using many advanced manufacturing processes, including: • 439 spot-welds using a GM-patented process that uses a unique electrode designed specifically for aluminum • 188 Flowdrill-machined fasteners installed by a high-speed drill that extrudes the frame material to create a strong, integral collar tapped for bolt-on fasteners • 113 feet of structural adhesives used in conjunction with welding and fasteners to increase overall frame stiffness • 37 feet of laser welds, which join frame sections via a precise beam of high energy that minimizes heat beyond the weld area for improved structural accuracy. The only structural differences between the Z06 Coupe and Convertible are provisions for mounting the power-folding top, and repositioned safety-belt mounts. High-performance aerodynamics Like the structure, only minor design changes distinguish the Z06 Coupe from the Convertible. The Z06 convertible features an electronic top that can be lowered remotely using the car's key fob. The top can also open or clos on the go, at speeds of up to 30 mph (50 km/h). With the top up, the Z06 Convertible is designed for a refined driving experience. A thick fabric top, offered in four colors along with sound-absorbing padding and a glass rear window, contributes to a quiet cabin and premium appearance. Behind the seat backs, dual accent panels – either Carbon Flash-painted or available with exposed carbon fiber – enhance the character lines of the tonneau cover. Corvette Stingray's signature "waterfall" design originates in the valley between the nacelles, bringing the exterior color into the interior. The power-operated tonneau cover necessitated moving the air intakes for the differential and transmission coolers from the rear quarter panels on the Z06 Coupe to the underbody of the Z06 Convertible. Otherwise, both models share the same, performance-driven aesthetic. "Practically every exterior panel serves a functional purpose to meet the performance goals of the Z06," said Tom Peters, Corvette design director, "The flared fenders accommodate larger, wider wheels and tires for more grip. The larger vents provide more cooling air to the engine, brakes, transmission and differential for increased track capability. The more aggressive aerodynamic package generates true downforce for more cornering grip and high-speed stability." Both Z06 models are fitted with Michelin tires (Pilot Super Sport tires for the Z06; Sport Cup 2 tires with the Z07 package): P285/30ZR19 front, and 335/25ZR20 rear. The tires are mounted on lightweight, spin-cast aluminum wheels (19 x 10 inches in front and 20 x 12 inches in the rear). Their open, ultralight design showcases the massive Brembo brakes, which contribute to the design: • The Z06 features two-piece steel rotors, measuring 14.6 x 1.3-inch (371 x 33 mm) front and 14.4 x 1-inch (365 x 25 mm) rear, with aluminum six-piston and four-piston fixed calipers, respectively • The Z07 package adds larger, 15.5 x 1.4-inch (394 x 36 mm) front and 15.3 x 1.3-inch (388 x 33 mm) carbon ceramic-matrix brake rotors for consistent performance lap after lap. They collectively save 23 pounds over the standard Z06 rotors. Both Z06 coupe and convertible will be available with one of three, increasing levels of aerodynamic downforce: • The standard Z06 features a front splitter, spats around the front wheel openings, a unique carbon-fiber hood with a larger vent, and rear spoiler • An available carbon-fiber aero package delivers aerodynamic downforce four times greater than the standard Z06. It adds a carbon fiber front splitter with aviation-style winglets, carbon fiber rocker panels, and a larger rear spoiler with a fixed wickerbill – a small, vertical tab at the edge of the spoiler that significantly increases downforce. The package is available in black or a visible carbon-fiber finish • The available Z07 package adds larger winglets to the front splitter, along with an adjustable, see-through center section on the rear spoiler enabling customers to tailor the aerodynamics to their preference. Compared to the Corvette Stingray, the Corvette Z06 fenders are 2.2 inches (56 mm) wider at the front, and 3.15 inches (80 mm) at the rear. Those extensions give the Corvette Z06 a wider, lower appearance further emphasized by a unique rear fascia. It incorporates the same taillamp assemblies as the Stingray, but on the Z06 the taillamps are pushed approximately three inches farther apart, toward to edges of the body. The exterior design also reflects the increased cooling required for the new Corvette Z06. For example, the mesh pattern on the front fascia was designed to deliver the most possible airflow to the supercharger's intercooler heat exchanger, so much that the mesh grill directs more air into the engine bay than if the grille was removed. The unique grille also features dedicated brake-cooling intakes and wider grille outlets on the bottom serve as air diffusers. A larger hood vent allows air driven through the grille to exit through the hood rather than being forced under the car, which could create lift. Standard front and rear brake-cooling ducts, including Z06-signature rear ducts integrated in front of the rear fender openings, are also part of the functional design changes. The Z06 benefits from interior details designed for high-performance driving, first introduced on the Stingray, including a steel-reinforced grab bar on the center console for the passenger and soft-touch materials on the edge of the console, where the driver naturally braces during high-load cornering. Like the Stingray, the Z06 comes with two seating choices: a GT seat, for all-around comfort, and a Competition Sport seat with more aggressive side bolstering, which provides greater support on the track. A magnesium frame structure for both seats provides greater rigidity and strength compared with steel frames. Unprecedented attention to detail and build quality complements the Corvette Z06's performance. All models feature a fully wrapped interior, with every surface covered by premium, soft-touch materials. Available materials, depending on the trim level, include Napa leather, aluminum, carbon fiber and micro-suede. The interior also features a flat-bottom steering wheel with a carbon fiber center spoke. The Z06 comes in five interior colors, including two that are unique to Z06 – blue and dark gray. Supercharged, efficient performance The heart of the 2015 Corvette Z06 is the all-new LT4 6.2L supercharged V-8 engine, expected to deliver at least 625 horsepower (466 kW) and 635 lb-ft of torque (861 Nm). To balance performance and efficiency, the LT4 leverages the same trio of advanced technologies introduced on the Corvette Stingray: Direct injection, Active Fuel Management, or cylinder deactivation, and continuously variable valve timing. These technologies – combined with the fuel-efficient multi-speed transmissions, aerodynamic design and lightweight construction – help make the new Z06 surprisingly fuel efficient. "The supercharged LT4 engine delivers the greatest balance of performance and efficiency ever in the Corvette," said John Rydzewski, assistant chief engineer for Small-Block engines. "It is one of the world's only supercharged engines to incorporate cylinder deactivation technology, enabling it to cruise efficiently on the highway with reduced fuel consumption, but offer more than 600 horsepower whenever the driver calls up its tremendous power reserve." The supercharged LT4 comes with a standard seven-speed manual transmission with Active Rev Match, or an all-new 8L90 eight-speed paddle-shift automatic transmission designed to enhance performance and efficiency. The seven-speed manual incorporates rev-matching technology for upshifts and downshifts. A new dual-mass flywheel and dual-disc clutch deliver greater shift quality and feel through lower inertia. The eight-speed automatic is tuned for world-class shift-response times. Smaller steps between gears keep the LT4 within the sweet spot of the rpm band, making the most of the output of the supercharged engine for exhilarating performance and greater efficiency. "There's no trade-off in drivability with the new 8L90 eight-speed automatic transmission – it was designed to deliver performance on par with dual-clutch designs, but without sacrificing refinement," said Bill Goodrich, assistant chief engineer for eight-speed automatic transmissions. "It is also the highest-capacity automatic transmission ever offered in a Chevrolet car." Featuring four gearsets and five clutches, creative packaging enables the GM-developed eight-speed automatic to fit the same space as the six-speed automatic used in the Corvette Stingray. Extensive use of aluminum and magnesium make it more than eight pounds (4 kg) lighter than the six-speed. Along with design features that reduce friction, the 8L90 is expected to contribute up to 5-percent greater efficiency, when compared with a six-speed automatic. Track-proven technologies The 2015 Corvette Z06 Coupe and Convertible leverage the technologies introduced on the Corvette Stingray, with unique features and calibrations tailored for its capabilities. "Our mission with the seventh-generation Corvette was to make the performance levels more accessible, enabling drivers to exploit every pound-foot of torque, every 'g' of grip and every pound of downforce," said Juechter. "It's a philosophy we introduced with the 460-horsepower Corvette Stingray – and one that's even more relevant with an estimated 625 horsepower at your beck and call." The new Z06 retains the SLA-type front and rear suspension design of the Corvette Stingray but uniquely calibrated for the higher performance threshold. The third-generation Magnetic Selective Ride Control dampers, adjustable for touring comfort or maximum track performance via the standard Driver Mode Selector, are standard on Z06. Like the Stingray, the Driver Mode Selector tailors up to a dozen features of the Z06 to suit the driver's environment, including: • Launch control: Available in Track mode for manual and automatic transmissions, providing maximum off-the-line acceleration • Traction control: Weather mode tailors traction control and engine torque for driving in inclement conditions • Performance Traction Management: Available in Track mode and offers five settings of torque reduction and brake intervention for track driving • Electronic Limited Slip Differential: Adjusts the rate at which the limited slip engages, balancing steering response and stability in different driving conditions with more aggressive performance in Sport and Track modes. The smart electronic limited-slip differential, or eLSD, is standard. It features a hydraulically actuated clutch capable of infinitely varying clutch engagement. The system enhances all aspects of performance by constantly tailoring the clutch-pack engagement based on a unique algorithm that factors in vehicle speed, steering input and throttle position to improve steering feel, handling balance and traction. Founded in 1911 in Detroit, Chevrolet is now one of the world's largest car brands, doing business in more than 140 countries and selling more than 4.9 million cars and trucks a year. Chevrolet provides customers with fuel-efficient vehicles that feature spirited performance, expressive design, and high quality.

    A customer got in touch with us with the intention of consulting on different methods of extracting more power from his E92 M3 DCT. Mentioning that he already had the aFe Stage 2 Intake and Eisenmann Sport Muffler, he wanted to get a host of modifications that added more growl and more importantly, add a lot of more punch to the S65B40. Explaining to him how the biggest power restriction on his car are the primary catalytic converters, we introduced him to the newly released Evolve Automotive Test Pipes. These test pipes are a bit unique compared to the competition because it features a very nice slip-on flange. We chose this method for the sake of assuring no risk of exhaust leaks, loose connections, and ease of installation. In addition to this, he expressed his concern with getting a CEL from the catalytic converter delete. He also really appreciated some of the neat features that we had with our tune. To really refine the power output from the Test Pipes, he decided to move forward with our Stage 2 Tune as well. Evolve Automotive Stage 2 Tune Features: Raised RPM Limit to 8500RPM Speed Limiter Delete Cold Start Delete 93 Octane EvolveR OBDII Cable Servo Tronic Calibration Exhaust Overrun Burble The work was carried out by our dealer Deans Performance Eurowerks in Chicago.

There are portions of the powerband with nearly 25whp/wtq gains! Not bad for a $450 piece of hardware. With Evolve's Stage 2 Tune, you can see how with the combination of fueling, ignition, and VANOS timing, the top end really comes to life. In our opinion, this is the 'best for your buck' for the S65B40. Photos: Evolve Automotive Stage 2 Package Definitely quite the difference in free flow. Getting everything all lined up. Perfect fitment right prior to bolting everything back in. Strapped onto the dyno for some pulls.

    APR continues to update their offerings and this is version 3.0 of their K04 turbo kit for the transverse mounted EA888 direct injected 2.0T engines. APR was able to get fairly large gains on the top end along with adding new features. The gain comes mostly in peak power and torque with version 3.0 offering 23 horsepower at the crank and 25 lb-ft of torque at the crank over version 2.0 on 93 octane pump gas. There is a dip however in the mid-range from 3000 to 4000 rpm. Why? APR has not explained why but it looks like some of the mid-range is being sacrificed for top end punch. The hardware remains the same so this is strictly a software change. What is admittedly pretty cool of APR is the software upgrade is free for existing ECU tune customers. They are not making a quick cash grab here like most would. For $2,474.99 it's hard to argue against the value here for 330 whp on pump gas and 349 whp on race gas from the 2.0T. This kit applies to several Audi and VW models which are listed below. v2.0 vs v3.0: 91 octane dyno: 93 octane dyno: 100 octane dyno: Applications: Audi A3 (MK2) Audi Q3 Audi TT (MK2) Volkswagen Beetle Volkswagen CC Volkswagen Eos Volkswagen Golf / GTI (MK5 / MK6) Volkswagen Jetta / GLI / Bora / Vento / Sigitar (MK5 / MK6) Volkswagen Passat / Magaton (B6) Volkswagen Scirocco Volkswagen Tiguan

    After years of development Porsche's LMP1 car is finally here. Porsche announced back in 2011 they would return to challenge for the overall Le Mans title and Porsche has periodically updated their progress which included a new facility built specifically for the design and testing of the 919 Hybrid you see here. Three years of work and countless hours of engineering passed and Porsche is ready to put it all to the test on June 14 to June 15 in arguably the most grueling race of the Motorsport season. It is not going to be easy. Toyota has a very strong challenger and Audi is prepared to defend their title with their best LMP1 car yet. So how does the 919 Hybrid stack up? The monocoque is made out of carbon fiber with an aluminum honeycomb core. The engine is a V4 gasoline engine with 2.0 liters of displacement that is turbocharged. It is said to make over 500 horsepower. The hybrid drivetrain features a KERS energy recovery system with water cooled lithium-ion battery packs that feed an electric motor on the front axle good for about 250 horsepower. Additionally, Porsche has two energy recovery systems including one that recoups thermal energy from the exhaust gases using an electric generator. This is a major point of differentiation between Porsche and the LMP1 competition. Porsche is likely sandbagging their power ratings a bit especially considering Toyota is bringing 900+ horses to the table. How much does it weigh? 870 kilograms, the minimum allowed and the exact same as the Audi R18 E-Tron Quattro. They managed to meet the minimum while conforming to updated safety regulations which certainly is impressive. How will Porsche fare after a 16 year absence during which Audi has dominated while Porsche did not participate in LMP1 competition? That is a good question. Toyota, Audi, and Porsche all have hybrid drivetrains but where they differ significantly is in their internal combustion approaches. Will Porsche's car with its 2.0 liter turbo gasoline motor and its thermal energy recovery system revving to 9000 rpm beat its larger displacement competition? Will Audi's turbo 3.7 liter diesel approach win out? Will Toyota's naturally aspirated 3.4 liter V8 prove to be too much to overcome? It is going to be a lot of fun to watch the world's best duke it out in a competition of endurance, engineering, and team driving on one of the most famous and storied Motorsport stages.

    Nice video here from BenzBoost member JonsC63AMG. He ran into a nasty sounding Mustang GT (turn your bass up when you play the video) that had full on bolt on modifications. The owner stated the GT put out somewhere in the 430 wheel horsepower range which based on the result seems about right. The C63 is a tune only car with a tune from OE Tuning. So who wins in a roll on race? Well, it was close. These cars are making similar power but the C63 is able to edge the Mustang up top. It certainly appears and sounds like the Mustang has a manual transmission and the consistency of the C63 auto edges it after a couple shifts. A very good race and it is nice to see a run in daylight in HD quality.

    Rejoice Chevy fans! The trick new 8L90 8-speed automatic gearbox will be available for the 2015 model year Stingray. There was some speculation that GM would not be able to roll the gearbox out for the C7 Z06 and the C7 Stingray at the same time but the 8-speed is available for 2015 model year orders. You probably are aware of the bold claims GM has made regarding the 8L90 specifically that it can shift faster than the Porsche PDK dual clutch. Whether it can or not remains to be seen but C7 performance just took a significant step forward especially if the 8/100's of a second quicker shift performance as stated in the press release below are true. This is the first time GM has provided some concrete numbers on the shifting performance and hopefully third parties replicate the claim. If it is true though, watch out. The C7 Vette just got even meaner. 2015 Corvette Stingray to Offer Eight-Speed Automatic Paddle-shift gearbox rivals dual-clutch performance, enhances efficiency DETROIT – An eight-speed paddle-shift automatic transmission will be offered in the Chevrolet Corvette Stingray for 2015, enhancing the performance and efficiency of the 2014 North American Car of the Year. Designed and built by GM, the new transmission delivers world-class shift times that rival the best dual-clutch designs. The all-new, GM-designed 8L90 eight-speed is expected to contribute up to 5-percent greater efficiency, when compared to the previous six-speed automatic. EPA fuel economy test results are pending and will be announced later. It also makes the Corvette Stingray one of the few sports cars to offer the choice of a conventional manual transmission or an eight-speed automatic. "Corvette Stingray's new eight-speed automatic delivers the comfort and drivability of a true automatic transmission, as well as lightning-fast shifts and the manual control that enhance the performance-driving experience," said Bill Goodrich, assistant chief engineer for eight-speed automatic transmissions. "It was designed to enhance the Stingray's driving experience, with performance on par with dual-clutch designs, but without sacrificing refinement." The available 8L90 transmission is based on the same eight-speed automatic that will be offered on the supercharged 2015 Corvette Z06, but with unique clutch and torque converter specifications matched to the torque capacity of the Stingray's LT1 6.2L naturally aspirated engine. For performance driving, the transmission offers full manual control via steering wheel paddles. A new transmission-control system and unique algorithms deliver shift performance that rivals the dual-clutch/semi-automatic transmissions found in many supercars – but with the smoothness and refinement that comes with a conventional automatic fitted with a torque converter. The transmission controller analyzes and executes commands 160 times per second. Wide-open throttle upshifts are executed up to eight-hundredths of a second quicker than those of the dual-clutch transmission offered in the Porsche 911. Smaller steps between gears, compared to the previous six-speed automatic, keep the engine within the sweet spot of the rpm band, making the most of its horsepower and torque to optimize performance and efficiency. With four gearsets and five clutches, creative packaging enables the new eight-speed automatic to fit the same space as the previous six-speed automatic. Extensive use of aluminum and magnesium make it more than eight pounds, or 4 kg, lighter than the six-speed. Design features that reduce friction contribute to the expected 5-percent greater efficiency. The 8L90 is built at GM's Toledo, Ohio, transmission facility. Founded in 1911 in Detroit, Chevrolet is now one of the world's largest car brands, doing business in more than 140 countries and selling more than 4.9 million cars and trucks a year. Chevrolet provides customers with fuel-efficient vehicles that feature spirited performance, expressive design, and high quality.

    The new Audi/VW 1.8 turbo direct injected four-cylinder fills the entry level gasoline spot in the model VW and Audi model range now. Volkswagen previously used a naturally aspirated 2.5 liter inline-5 but this is the motor replacing it. It is based on the larger 2.0T model so they share the same EA888 engine architecture. With 170 horsepower and 200 pound-feet of torque it is not a powerhouse but the turbo torque out of the small displacement motor definitely shows potential. So how does the engine fair in the A3? Consider first that this A3 only weighs 3108 pounds. Pretty light for an Audi sedan, right? Consider next that this motor in the A3 is available in front wheel drive only which means the car achieves that curb weight thanks to ditching Quattro. Despite the low weight and S-Tronic dual clutch gearbox acceleration is fairly lackluster with 0-60 coming in 6.8 seconds and the 1/4 mile in 15.4 @ 89.4. Certainly nothing special but with a tune this might surprise a few people. However, once you start adding power and torque that front wheel drive traction will become a problem. Is it better to opt for the 2.0T Quattro models despite their heavier weight? The price hit is $3,000 for the larger motor and all wheel drive so unless price is the deciding factor the 2.0T makes more sense especially if one is interested in performance or tuning... like AudiBoost is. 2015 Audi A3 1.8T BASE PRICE $30,795 PRICE AS TESTED $34,545 VEHICLE LAYOUT Front-engine, FWD, 5-pass, 4-door sedan ENGINE 1.8L/170-hp/200-lb-ft turbo DOHC 16-valve I-4 TRANSMISSION 6-speed twin-clutch auto.

    Congratulations are in order to this E55 and Eurocharged who tuned it for setting a new quickest and fastest overall W211 E55 AMG record. The bar now is set at 10.39 @ 134 in the 1/4 mile. The car achieved with basically with aggressive engine and transmission tuning along with a fairly big 150 shot of nitrous. The E55 is still on the stock 2.1 liter OEM Lysholm supercharger which definitely is holding it back a bit but that is where the nitrous comes into play. The mod list includes a 82mm throttle body, 185mm pulley, long tube headers, 150 shot, upgraded heat exchanger, Wavetrac limited slip differential, and of course drag rubber. Video and slip below, congratulations to all involved.

    The APR Stage III kit on the Golf R we know is plenty potent with capability of over 400 horsepower at the wheels courtesy of the Garrett GTX2867R turbocharger. So how does it put all the power down from a stop? Incredibly well. This Golf R from China is running 93 pump gas. It is a DSG model so that partially explains the quick time. Additionally, it is on Yokohama AD08 tires at all four corners which offer pretty good grip. The result is a VBOX verified 0-60 time of 3.1 seconds. That is a four cylinder Golf doing a 0-60 sprint in almost 3 seconds flat. Oh VW, why didn't you give those of us in the USA the DSG transmission? Video below, pay no attention to the atrocious music.

    The entry level compact SUV market is lucrative and becoming increasingly competitive. BMW has their X1 and Mercedes-Benz has the GLA-Class in this segment. Lexus intends to challenge them with their brand new entry level 2015 NX SUV. The styling is subjective and incorporates the new Lexus styling language with the large and prominent front grille. It gives somewhat of a gaping hole look but that is what you can expect to see on new Lexus models. The design definitely is modern and it works. The inside of the car is not as progressive as the exterior. It just is not on par with BMW or Mercedes. It simply looks Japanese with a lot of plastic and rubber. The red stitching is fairly nice but the interior is not going to set any class standards. So let's talk about the motor options. Yep, turbocharged power for a Lexus. The NX200t features a 2.0 liter turbocharged motor with direct injection. It feels like everyone has a turbo 2.0 liter four-cylinder these days. The other engine option is a six-cylinder hybrid NX 300h model for the United States. So is the power output? Lexus omits this bit of information which is kind of important. With all wheel drive and good output this may be fun to drive if the weight is low. Considering this is Lexus though expect the car to not have much of a personality and be more transportation than fun. Maybe the F-Sport model will be different as Lexus hints at increased performance. We will have to wait for additional details, enjoy the pictures and press release. All-New Lexus NX Compact Crossover Launches With Marque's First Turbo Powertrain Available With Three Powertrains: Gasoline Turbo NX 200t, Naturally Aspirated NX 200, and Full Hybrid NX 300h Lexus Enters Luxury Compact Crossover Segment NX Reveal at Beijing International Automotive Exhibition on April 20 BEIJING – April 11, 2014 – There's a first for everything! The all-new Lexus NX comes to market as the brand's first entry into the luxury compact crossover segment and with the first turbo in the lineup. The NX will also be offered in naturally aspirated and hybrid powertrains. Powertrains will vary by region. The U.S. market will offer the NX 200t turbo and NX 300h hybrid. The NX 200t F SPORT will also be available with unique exterior and interior features. Lexus will maintain its role as the luxury hybrid leader with six hybrid models including the NX 300h. The NX will be the fourth vehicle in Lexus' luxury utility vehicle lineup and positioned below the popular RX. The Lexus LF-NX concepts, originally introduced at the 2013 Frankfurt and Tokyo Motor Shows, influenced the striking and emotional design of the NX. The sharply styled crossover will be revealed at the 2014 Beijing International Automotive Exhibition on April 20. Chief engineer Takeaki Kato and his team developed NX as a luxury vehicle that provides versatility and details unexpected in its class to young, urban drivers. Exterior Design The NX was developed to have more agility than a SUV plus a bold, eye-catching exterior with its low profile and unique roofline. As with all Lexus vehicles, the aggressive exterior starts with the spindle grille. Innovative LED headlamps and daytime running lamps firmly express Lexus' bold styling. The front and rear wheel arches add to the NX's wide and low, muscular stance with bold flares. The arches house standard 17-inch or available 18-inch wheels. The profile is accentuated by a roofline peak set towards the back of the vehicle to create a tight silhouette and provide ample head-room for rear seat occupants.  Subtle, luxury details are included in the innovative Lexus-first door handle with a hidden key barrel and integrated lighting. The rear is punctuated by Lexus' signature 'L' shape combination lamps, each with seamless LED lighting, while the bodywork echoes the spindle grille design. The NX 200t F SPORT will feature exclusive design elements and enhanced driving performance. Interior Design The NX's cabin combines the structural beauty of a high-performance machine with luxury materials that maximizes functionality. The combination of hard metallic surfaces and contrasting soft materials help create a unique interior. A strong, center silver frame surrounds and defines the center instrument panel. Knee pads located at the base of the center stack help support the driver and passenger. The Human Machine Interface (HMI) technology continues the impression of an advanced vehicle and is also located at the bottom of the center stack. Seating played a significant role in the cabin design. The NX possesses a low hip point adding to the connection of the driver to the vehicle and increasing overall head room. The NX also has a long cargo area length and a wide front to rear couple distance. Technology The NX introduces an innovative all-new 2.0-liter gasoline turbo in NX 200t and a naturally aspirated engine in NX 200 with the choice of front and all-weather drive. Lexus also offers a highly efficient hybrid in NX 300h. The NX has an array of innovative on-board technology, including an available Lexus-first Wireless Charging Tray to enable a mobile phone to be charged. Other available technology includes the first application of a new Lexus Remote Touch Interface with a touch pad; and a comprehensive Multi- information Display, including a Lexus-first G sensor and boost meter, Heads-Up Display, All-speed Dynamic Radar Cruise Control, Blind Spot Monitor with Rear Cross Traffic Alert.

    Defending champion Corvette Racing took the victory at this past weekend's Long Beach Grand Prix. Corvette Racing impressively got both of their entries on the podium due to their 1-3 finish. BMW also got on the podium thanks to a second place finish from the number 56 Z4 GTE. BMW's second Z4 (number 55) finished in 6th place. Keep in mind it is still early in the season but here are the USC (United Sportscar Championship) GTLM standings after three races. Porsche is in first place with 100 points followed by BMW with 94. SRT is doing an impressive job with the new Vipers sitting one point in front of Chevy in third place with 90. Ferrari is in last place with 80 points. Corvette Racing won the Long Beach Grand Prix in their new C7R which seems to be running much stronger. They dominated the race leading all but two laps. Drivers Antonio Garcia and Jan Magnussen took the victory and Magnussen had this to say, "It was an important victory for the team. The whole time we had a fast car. We just didn't make the most of it with reliability issues at both Daytona and Sebring. I couldn't be happier for Antonio, myself and this entire team.” The next Grand Prix is May 3rd-4th in Monterey. There is a long way to go but Chevy's strong result bodes well for the rest of the season.

    You already know that Audi dominates the 24 Hours of Le Mans. Last year, they won with a hybrid drivetrain. Electric motors and batteries add significant weight so it is incredibly impressive the 2014 car with an evolution of this hybrid drivetrain while meeting new safety requirements is able to cut 99.2 pounds off the 2013 car. That makes for a total weight of only 1918 pounds. Yes, under 2000 pounds for a 900+ horsepower Le Mans Prototype with a hybrid drivetrain. Simply incredible progress and it looks like Toyota has their work cut out for them with their 2014 TS040 LMP1 car. Porsche is also about to have an intense fight on their hands with their 919 Spyder LMP1 car going head to head with Toyota and Audi. The 2014 24 Hours of Le Mans is shaping up to offer the most competitive LMP1 battle in a long, long time. Audi designs lightest sports prototype in its history Audi R18 e-tron quattro represents multiple optimization of light-weight design Lower weight, higher safety and fuel economy: No Audi Le Mans prototype has ever been as efficient New safety rules increase requirements Audi had to master a particularly challenging task before the 2014 season. Since the brand entered Le Mans prototype racing in 1999, the safety rules have never been as strict and a race car as complex as this year. At the same time, the car is allowed to be lighter than ever before. Design engineers – whether in production or race car engineering – are tasked to resolve target conflicts on a daily basis. However, the concept design of the new Audi R18 e-tron quattro confronted the engineers at Audi Sport with a particularly challenging requirement. On the one hand, the racing weight of the LMP1 cars compared to last year is allowed to decrease from 915 to 870 kilograms. 45 kilograms less weight make a significant difference in racing. At the same time, the new technical regulations contain various requirements that call for completely new solutions which lead to an increase in weight. For example, to protect the driver in the case of lateral impacts, the regulations prescribe Zylon side panels. This particularly tough and impact-resistant material prevents lateral intrusions of pointed objects in the cockpit in an accident. The monocoque itself had to be redesigned as well to withstand the higher test loads specified starting in 2014. The eight wheel tethers (two per wheel) which are to prevent the separation of the wheels from the car in case of a crash are new as well. Furthermore, the 2014 Audi R18 e-tron quattro is equipped with a rear crash absorbing structure. This new component made of carbon fiber reinforced plastic (CFRP) absorbs the energy in a rear-end collision. And, last but not least, the regulations now allow transmissions with seven instead of the previous six forward gears. The new gear pair and its actuation make a difference on the scales as well. “The aggregate of all these measures corresponds to an additional weight of more than 20 kilograms,” explains Dr. Martin Mόhlmeier, Head of Technology at Audi Sport. As a result, the engineers were tasked to make the newly designed race car even lighter than before – to compensate for this additional weight while achieving the lower minimum weight. “Thanks to our constant development work there are no measures left that would yield major weight savings in a single step. Instead, the art lies in achieving further improvements of all the details,” says Wolfgang Appel, Head of Vehicle Technology at Audi Sport. Audi has consistently increased the CFRP content in the race car. In the 2014 season, the steering wheel column of the sports prototype is made from this material for the first time. However, this material continues to be prohibited in various areas. For instance, the wheel suspension elements still have to be made of metallic materials, according to the regulations. Due to these regulatory specifications and technical options the room for maneuver becomes increasingly constrained year after year. In spite of this, Audi achieved its target weight in the R18 e-tron quattro for the current season. The diesel hybrid sports car meets the limit of 870 kilograms. In total, the new Audi R18 e-tron quattro is safer, lighter and more efficient than any of its predecessors, and Audi’s light-weight technology has a major part in this. For more than 20 years, the company has been proving its expertise in this area in the development of its production cars as well.

    Andy Palmer, Nissan Vice President, stated that hybrid electric systems are inevitable for future vehicles and that includes the next generation R36 GT-R. He stated, “There is an inevitability about electrification of all cars in the future, and there is the very real prospect of enhancements coming from it on a sports car like the Nissan GT-R. The electric systems can fill in the gaps in the torque curve and offer genuine performance gains, as well as lowering emissions." He is not wrong. Porsche and McLaren both have demonstrated high performance hybrids are not only possible there is a performance benefit from the instant torque of the electric motors. What this means for tuning of the R36 is that it is going to get a bit more complex. The well known VR38DETT will be used again although revamped with more horsepower and who knows what the combined output will be with the electric motors. Tuners are going to have to start playing with electric motors and gasoline motors while making sure it all works well together meaning a whole nother level of complexity. The nice thing is performance cars are not going to be abandoned in the upcoming generations. They just will be forced to evolve.
