    This is what you can call a serious N54 build. @Ericbh77 is not messing around with his E92 335i. He is going for roughly 1000 horsepower and what is making that possible is the custom Fab Factory bottom mount twin scroll turbo manifold mated to a PTE 6870. The motor is obviously built and he is going with Schrick high lift cams: VAC built the motor and did some head work as well. He is planning on having @CKI@Motiv tune it and additional fuel is coming from a supplemental HPFP pump. Most high horsepower builds like this tend to be manual as the automatic will not hold the torque. Will this one? We'll see as it features upgrades although they have not been tested at this level. This is going to be a fun build to watch come together. Enjoy the pictures below.

    MotorTrend got their hands on these two German hot rods featuring 3.0 liter twin turbo powerplants. The engine design is quite different however with the 911 GTS 9A2B6 featuring an oversquare flat-6 and the M4 S55 featuring an undersquare inline-6 which BoostAddict previously covered in an engine design comparison article. That said on paper these cars match up well. The M4 obviously offers greater value but it is heavier and seats four adults. The 911 does not seat four adults but is roughly 200 pounds lighter and of course more expensive. Power is essentially a wash on paper but we really need to see them both on the dyno to know the truth regarding torque curves, spool, and output. Unlike BMW who just changes software for the output gain, Porsche gives you larger turbos with the GTS. This GTS is rear wheel drive just like the M4 and both have dual clutch transmissions so this is as apples to apples as we are going to get. Ok, let's get to the actual performance comparison! They get the cars out on the Nurburgring and how can you not love that? Well, they ruin the whole thing by not providing laptimes. WTF is the point here guys? You attend a track day, talk about factory laptimes, and provide no actual performance measures. MotorTrend should never be allowed to take cars on the 'Ring again. What happens after the big Nurburgring buildup that ends in a whimper? They go on some damp and foggy mountain road and continue to yammer on about their feelings. Where is the Head 2 Head performance comparison gentlemen? You might as well have grandmothers compare these cars. What a waste of time MotorTrend. Don't call it a Head 2 Head comparison when really it is just story time with Jonny Lieberman and some guy who has an English accent which obviously means he has to know cars. You guys are a joke.

    Well, holy crap! 8's out of the box? A 250 mph top speed? That is not all. The new Tesla roadster is said to hit 60 in 1.9 seconds and it will hit 100 miles per hour in 4.2 seconds. Those numbers are so mind numbingly fast please excuse us for being skeptical. When will it hit the market? Apparently it is being positioned as a 2020 model year car. The battery capacity is said to be good for 630 miles. Three motors will supply over 7,000 lb-ft of torque. It will start at $200,000 which for the numbers Tesla is quoting is well worth the money. Hell, it's worth double. It is going to be very hard to argue against the new Tesla Roadster if it delivers as advertised. The only downside will likely be the heft.

    This BMW E92 335i belongs to BimmerBoost member @PureEvilN54 and he recently swapped a DCT (dual clutch) transmission into his 335i. Pulling off the physical swap is one thing but he states he is able to get launch values others are not. For example, 3500 and 5000 rpm launches. In the video below he demonstrates a 3500 rpm launch that builds 4 psi off boost at the line and he tells BimmerBoost that thus far he is the only one doing this launch control RPM value on a DCT swapped N54. BimmerBoost would love to see confirmation of that 5000 rpm launch.

    According to Car and Driver's Porsche 991.2 GTS test results it is right there with Porsche 991.1 Turbo models. Actually, the 125 mile per hour trap speed is faster than the 123 MotorTrend got for the 991.1 Turbo but the 991.1 Turbo is known for being inconsistent. The 991.2 GTS model certainly is impressive and those larger turbochargers are doing some serious work. Realistically, expect 122-123 on the dragstrip based on the 991.2 Carrera S running 11.5 @ 120. An all wheel drive GTS likely will be knocking right on that 10-second door in stock form. Now imagine it with a tune... easy mid-10's? High 12X traps? The car is not just about acceleration obviously although clearly it is overachieving for 450 horsepower. The curb weight is fairly light at 3335 pounds and the handling plus steering feedback is stated as phenomenal. Honestly, it is hard to argue against the 911 GTS as the best sports car in the world produced today for the money. They're not wrong. VEHICLE TYPE: rear-engine, rear-wheel-drive, 2+2-passenger, 2-door coupe PRICE AS TESTED: $129,560 (base price: $123,770) ENGINE TYPE: twin-turbocharged and intercooled DOHC 24-valve flat-6, aluminum block and heads, direct fuel injection DISPLACEMENT: 182 cu in, 2981 cc POWER: 450 hp @ 6500 rpm TORQUE: 405 lb-ft @ 2150 rpm TRANSMISSION: 7-speed dual-clutch automatic with manual shifting mode DIMENSIONS: WHEELBASE: 96.5 in LENGTH: 178.3 in WIDTH: 72.9 in HEIGHT: 50.6 in PASSENGER VOLUME: 70 cu ft CARGO VOLUME: 5 cu ft CURB WEIGHT: 3335 lb C/D TEST RESULTS: Zero to 60 mph: 3.0 sec Zero to 100 mph: 7.2 sec Zero to 130 mph: 12.2 sec Zero to 150 mph: 17.4 sec Rolling start, 5-60 mph: 3.8 sec Top gear, 30-50 mph: 2.4 sec Top gear, 50-70 mph: 2.5 sec Standing -mile: 11.3 sec @ 125 mph Top speed (drag limited, mfr's claim): 193 mph Braking, 70-0 mph: 142 ft Roadholding, 300-ft-dia skidpad: 1.05 g C/D FUEL ECONOMY: Observed: 20 mpg EPA FUEL ECONOMY: Combined/city/highway: 23/20/26 mpg

    Well, I think this is the last video of the Evil 1 that i will be able to claim... Matt, the new owner, took her to a local (TX) dyno day on Saturday and she did well! First pull she actually blew the tires off on the rollers! Man card achievement unlocked! 637/533 at 26lbs the street map with the AC on (read mixed feedback on this robbing power or not). Next up is going to be all his project. With the Fuel Return from Fuel-It and support from BMS and EMP, I expect him to get 7-750whp out of it!!

    This E82 135i used to belong to BimmerBoost member @trickcruiser. He sold it but here are some final dyno pulls from his ride. This is a stock head and stock block N54. It is running a Precision 6466 single turbo with a VM N54 manifold. Going beyond this power and torque for a daily driven automatic N54 is asking for reliability concerns: The transmission was rebuilt by Level 10 but they have mixed reviews to say the least. Look to them more to refurbish an auto box than anything else on the platform. A solid 637 wheel horsepower and 533 lb-ft of torque in street trim on an E85 tune. The fuel system is a Fuel-It! Stage 3 with port injection and a BMS controller. It will be interesting to see if the new owner intends to push it much further.

    The next generation BMW F80 M3 and G82 M4 models expected as 2020 model year cars will feature new engine architecture. Well, not exactly new as the S58B38 powerplant will be a tweaked version of the current B58 3.0 liter inline-6 motor we all know and love. A water injection system carries over from the F82 M4 GTS. BimmerBoost would expect enthusiasts to quickly supplement this system with methanol injection or a mix. The reason the B58 will become an S58 is because BMW no longer builds ground-up M motors. A cost cutting move but it is redundant at this point to keep bringing up BMW heavily cutting costs. On the bright side the B58 architecture is a departure from the N54/N55/S55 engine family and hopefully that means we will not see crank hub issues with the new M3 and M4 engine. BMW can not possibly get this wrong for two straight generations, right? As the M3 and M4 are going up in power all wheel drive is expected to be standard. BMW may indeed quote 493 horsepower but this will be closer to an output rating at the wheels than at the crank. If BimmerBoost were to guess, BMW will continue to increase the M3/M4 base model by 70 whp so 490 horsepower at the wheels is pretty much the right range. The problem here is that the car will gain weight. All wheel drive is not going to make the vehicle lighter. Another problem is it likely means the end of a dual clutch transmission. A manual does not look likely either. An automatic all wheel drive M3? Why not just buy an Audi? There is a rumor that there will be a hybrid system. If so, expect weight to balloon further. If not, thank goodness. BMW will likely save face by allowing software to put the vehicle in a rear wheel drive mode just as they do with the F90 M5. The new M3 and M4 models will no doubt kick ass on the dragstrip and easily put their power down off the line. In other words, they will be nothing like what they are supposed to be.

    Hoping not to get beat up in this post...but here it goes... If I buy the boostbox from Motiv then my costs are: Boostbox - $200 Motiv Propiatary tune - $300 with single turbo option selected MHD Flasher - $99 MHD logger - $69 MHD increased boost limit - $49... Grand Total - $717 Or I can get a JB4 with a BEF for $479 Or hell even a Procede for $700 brand new... Granted, I don't endorse the Procede by any means necessary, but just simply looking at it all. Only reason that I even ask this is due to someone contacting me that has a single turbo swap with a boostbox that they purchased when they bought their single turbo kit... I got on their computer and setup the BB App to flash the car. After finding out all of the details of his modifications it was apparent that he didn't want to spend any more money to get the car to work properly. After attempting to flash multiple times and no boost working I finally read on the Motiv website that it requires a 'lite' tune file to allow it to work properly... Without knowing what the changes are or the xdf referencing these changes I was unable to assist him. Therefore I asked him to remove the boostbox and sell it, rehook up his JB4 from prior to the Single Turbo swap, flash the custom JB4 firmware, flash the dme with a backend flash from the BB App and BAM!!! It worked amazingly! I understand this is a business and all, but at least have the decency to allow customers to have options in flashing. Double dipping from having people utilize one flashing platform over another and purchasing your products is sort of a poor attempt to monopolize the market. The main reason I'm attempting to assist the market is so that the community can purchase more upgrades for their vehicles without being "taxed" for each level of upgrade. The BB App works for flashing any of the MSD80/81/85 vehicles just as well as the MHD tool does. Is there any timeframe for when the new xdf's will be released?

    The new 2019 Corvette ZR1 LT5 motor illustrates the point well that direct fuel injection on its own is not the best choice for a performance car. You will notice an increasing trend of high performance cars coming to the market with dual fuel injection. That means both direct and port fuel injection systems. Why both? Because direct injection quickly becomes a liability. The technology spread due to efficiency benefits not because it was better for performance. Want to disagree? Tell it to McLaren who for some reason opted not to equip the McLaren 720S M840T V8 which is absolutely vaporizing all challengers with direct fuel injection. The issue is not only do you need strong pumps capable of huge pressure the injection window shortens with RPM. That makes it a challenge to provide enough fuel at higher rpm ranges. This is exacerbated as power as added. Let's assume for a moment you buy a Ferrari 458 which has a direct injected motor that revs to 9k rpm. You might be saying, what is the problem? Well, try running ethanol through the motor. As ethanol contains less energy than gasoline while at the same time offering higher octane and cooling benefits you need to flow more of it through your fuel system. The direct injection system quickly taps out. It only gets worse if you add power. Port fuel injection does not have the same injection window or pressure issues. This is probably why McLaren does not use it on its 8000-8500 rpm motors. This is probably why Ford does not use it on the 8200 rpm GT350 Voodoo V8. This is probably why BMW M did not equip the S65 V8 or S85 V10 8250+ rpm screamers with direct injection. Manufacturers building performance engines today with direct injection are increasingly offering dual injection systems with port fuel injection. Why? To alleviate stress on the direct injection system and offer fueling headroom say with modern ethanol blends. It also reduces carbon deposits. There are pluses and minuses to both approaches. Direct injection allows motors to run at higher compression before detonation on pump fuels. This obviously provides a power and efficiency benefit. The cooling effect of direct injection is due to fuel droplets going through a phase change from liquid to gas and becoming an ignitable vapor that can be mixed with air and detonated by the spark plug. Heat is absorbed during this change providing a cooling effect which will allow a direct injection motor to run leaner. Again, this provides an efficiency benefit when it comes to fuel use. Port injection allows air flowing through the intake manifold to cool before reaching the combustion chamber while direct injection provides its cooling benefit in the chamber itself. Port injection also does not require the high injection pressure and it does not have the limited injection window which means it is easier to flow far more fuel. You can see how combining these two technologies provides the benefits of both and minimizes the downsides. Just look at the performance motors that recently entered the market with dual fuel systems: Chevrolet LT5 Audi 2.5 TFSI Audi/Lamborghini 5.2 V10 Bentley W12 Ford 3.5 Ecoboost There are other motors with dual injection not listed there but you get the idea and more are on the way. It is interesting to note that many enthusiasts on the various BoostAddict sites with direct injected motors who add power look into adding supplemental port injection systems. It is ironic that getting away from port injection quickly leads them right back to port injection once they start to add power and run ethanol. Factory dual-injection tends to provide the best of both worlds.

    The E46 M3 CSL originally made waves because it managed a stellar 7 minute and 50 second laptime in the hands of Sport Auto. Back in 2003 this was a quick time. For perspective, a 997.2 Carrera S PDK on Michelin Pilot Sport Cup tires matched this time in 2008. The CSL was spectacular. BMW shaved 240 pounds off the car for a total of 3053 pounds and managed to squeeze 360 horsepower out of the 3.2 liter S54 engine with a new airbox design and a new cam profile. Not to mention the suspension, aerodynamics, and brake upgrades. The E46 M3 CSL was BMW M at its best and the peak of the classic M brand. That 7:50 Nurburgring time was an incredible achievement. Now in 2017 look at what this E46 M3 is doing. A 7:28.5 and yes it is still naturally aspirated. The M3 has a CSL airbox from Karbonius Composites and a CSL tune from Chris Benoit. This of course is in addition to the suspension, brake, aero, and tire upgrades. An absolutely phenomenal result when you factor in the E46 record holder is a supercharged E46 M3 CSL running 7:22 and the a stock F82 M4 takes 7 minutes and 52 seconds. The driving probably has something to do with it.

    So I'm looking to get a intercooler,I want the Race intercooler ,it's between the Pheonix Race and Vrsf Race intercooler.From what I gathered so far is... Pheonix(BMS)Race Intercooler Pros Good price 499.00 3"in/out Hotside diverter Comes coated(painted)to help heat transfer VRSF Race Intercooler Next decent price 569.00 3"in/out Comes with 3" JPipe Has better tabs for radiator support So difference between the Intercoolers is minor but can make a difference.the Pheonix has the hotside diverter while Vrsf doesn't,but the vrsf has 3" JPipe while the Phoenix doesn't. Also the vrsf has better radiator tabs then the Pheonix Now as for the core I'm hearing it's the same as vrsf if not better from what I have gathered.Now the radiator support brings up a concern that the Pheonix has as oppose to the vrsf.im not sure which way to swing since it's close but the vrsf has been out for some time and the Phoenix is new to the market.not sure which way to go.looking for some help :think:

    At this point it is difficult to deny that the N63/S63 engine architecture is the best from a tuning perspective in the BMW turbo era. The various N54, N55, and S55 I6's may be more plentiful but they simply are not as stout stock or modified. The S63TU will make about 500 whp in stock form on a standard F10 M5 depending on your dyno and the weather. BMW sandbagged the hell out of the motor like they do with most of their M motors theses days. So it's stout stock but how do you add 300+ whp to it? Like this: - Pure Turbos Stage 2 turbocharger - DCT clutch upgrade - Tuning - Catless downpipes and an exhaust Here's the proof: This is an example tuned by HC Performance through the PTF Bootmod3 system. The engine remains stock internally. Horsepower is boosted by 300 at the wheels and torque goes up from 484 lb-ft at the wheels to 854 lb-ft at the wheels. Pushing the motor further on the factory rods is not recommended but if you want more there are people going well past 1000+ horsepower with built motor examples. This basic engine design is going to be with us for a while through the F90 M5 and beyond. That is a good thing. It would be even better if BMW put the motor in a chassis that didn't weigh 4300+ pounds.

    Nobody should be surprised that the new F90 M5 is starting at over $100k. The military pricing leaked out and even with the military discount it is over $100k. To be precise, $102,600 which means the MSRP is going to be above this amount. For reference, the 2016 BMW F10 M5 starts at $94,100. We can expect at least $10k more. Whether it is worth it or not is up to you to decide. The price quickly goes up with options. The First Edition option is $18,300 and includes the M Sport Exhaust system (which is a must) along with 20 inch wheels. Then there is the Apple Car Play, Black Trim, Surround Sound System, high-gloss Shadow line, M Driver's package, and some BMW individual components. Realistically that makes this potentially a $130k+ car out the door once you start ticking boxes. Is it worth it? We'll see soon enough.

    The Balboni edition of the Lamborghini Gallardo does not get the credit it deserves. The car is named after the legendary Lamborghini test driver Valentino Balboni. This man was responsible for testing every Lamborghini introduced since 1973 until his retirement. The Balboni edition was built to be the way Valentino would want a Gallardo. That meant a lighter and sharper car where the throttle could be used to correct. The all wheel drive system was ditched saving over 250 pounds. The result is a curb weight of 3042 pounds. What could be better than a lightweight Gallardo with a high revving 542 horsepower 5.2 liter V10? That same motor with a supercharger from VF-Engineering. Check out the difference between stock and with the Eaton TVS2300 kit from VF: Another 180 horsepower at the wheels over stock. Oh, and how about 178 more lb-ft of torque? The Balboni is supposed to be a track car and there will be those people saying you can not track it with a blower due to heat soak. Oh yeah? Check out these three pulls back to back to back: Looks like VF has the cooling down just fine. This is the definition of a driver's Lamborghini just as Balboni wanted it... but even better.

If not, thank goodness. BMW will likely save face by allowing software to put the vehicle in a rear wheel drive mode just as they do with the F90 M5. The new M3 and M4 models will no doubt kick ass on the dragstrip and easily put their power down off the line. In other words, they will be nothing like what they are supposed to be.

    Nobody should be surprised that the new F90 M5 is starting at over $100k. The military pricing leaked out and even with the military discount it is over $100k. To be precise, $102,600 which means the MSRP is going to be above this amount. For reference, the 2016 BMW F10 M5 starts at $94,100. We can expect at least $10k more. Whether it is worth it or not is up to you to decide. The price quickly goes up with options. The First Edition option is $18,300 and includes the M Sport Exhaust system (which is a must) along with 20 inch wheels. Then there is the Apple Car Play, Black Trim, Surround Sound System, high-gloss Shadow line, M Driver's package, and some BMW individual components. Realistically that makes this potentially a $130k+ car out the door once you start ticking boxes. Is it worth it? We'll see soon enough.

    TTE (The Turbo Engineers) in Germany has a hybrid S55 turbocharger upgrade available for the F80 M3 and F82 M4. When it comes to hybrid turbos Pure Turbos pretty much dominates the S55 platform but it is interesting to finally see some results from the TTE turbochargers. Another interesting point is that this F80 M3 is tuned through the MHD F-Series OBD-II platform. Up until now, most upgraded turbo F80 M3 and F82 M4 vehicles were tuned through the PTF Bootmod3 system. The results look good: 717 horsepower at the crank is strong. However, what kind of dyno is being used? We need to see more numbers on a variety of dynamometers to get a better idea of output. Additionally, to see how this stacks up to Pure Turbos efforts. As for the MHD F-Series platform it is flashed through OBD-II and a handheld device except the ECU must be unlocked physically first. This is no different from the PTF Bootmod3 system in that respect. No doubt European members will be more interested in the TTE S55 turbos than those in the USA.

    Mercedes-AMG is essentially offering the same engine architecture in various state of tune. The M176, M177, and M178 V8 motors are all the same basic design and engine family but there are differences based on the application. For example, the M178 gets a dry sump oil lubrication system as AMG GT owners are more likely to track their cars. Plus, there is a large price premium so it makes sense the top model gets all the goodies. The C63 and E63 both have an M177 4.0 liter twin turbo V8 yet the output is very different between the two. How do they differ? W205 C63 S Displacement: 3982cc Bore x Stroke: 83mm x 92mm Horsepower: 503 Torque: 516 lb-ft Redline: 7000 rpm Compression Ratio: 10.5:1 Boost: 17.4 psi W213 E63 S Displacement: 3982cc Bore x Stroke: 83mm x 92mm Horsepower: 603 Torque: 627 lb0ft Redline: 7000 rpm Compression Ratio: 8.6:1 Boost: 21.8 psi What should immediately strike you is that the E63 S has higher boost pressure but also lower compression. Much lower compression. Why? Well, because Mercedes-AMG is cramming in a lot more air. It is the same compression ratio as the M133 four-cylinder in the CLA45 AMG. The main difference is that compression ratio and the turbochargers. As the E63 S is 500 pounds heavier plus sending power to all four wheels courtesy of 4Matic it needs much more power and torque to move it. Especially considering that it is priced above the C63 in the lineup. The new twin scroll turbochargers ensure the E63 S is making more power and torque. There is a bit of a trade off in lag but past 3000 rpm until redline there is a massive difference in area under the curve in favor of the E63 S: The Renntech tuned E63 S is making nearly 120 more horsepower than the Renntech tuned C63 S. Maybe swapping E63 turbos and manifolds onto the C63 will become popular? The E63 also gets new pistons as already highlighted plus a new intake manifold and intercooler design. There you have it.

    At this point it is difficult to deny that the N63/S63 engine architecture is the best from a tuning perspective in the BMW turbo era. The various N54, N55, and S55 I6's may be more plentiful but they simply are not as stout stock or modified. The S63TU will make about 500 whp in stock form on a standard F10 M5 depending on your dyno and the weather. BMW sandbagged the hell out of the motor like they do with most of their M motors theses days. So it's stout stock but how do you add 300+ whp to it? Like this: - Pure Turbos Stage 2 turbocharger - DCT clutch upgrade - Tuning - Catless downpipes and an exhaust Here's the proof: This is an example tuned by HC Performance through the PTF Bootmod3 system. The engine remains stock internally. Horsepower is boosted by 300 at the wheels and torque goes up from 484 lb-ft at the wheels to 854 lb-ft at the wheels. Pushing the motor further on the factory rods is not recommended but if you want more there are people going well past 1000+ horsepower with built motor examples. This basic engine design is going to be with us for a while through the F90 M5 and beyond. That is a good thing. It would be even better if BMW put the motor in a chassis that didn't weigh 4300+ pounds.
