    Many European BimmerBoost members feel slighted as they do not have as many turbocharger options as US members. Well, in comes Lynx to the rescue as they are a European based N54 turbo option operating out of Switzerland. The Lynx turbochargers are available in two options: RT-650 and RT-750. As implied in the name, the 650 supports up to 650 horsepower and 750 up to 750 horsepower. Simple, right? Let's look at the design. The turbochargers feature cast manifolds and housings. The manifold diameter is larger than the hybrid options on the market as is the A/R of the turbine housing. High performance bearings are utilized. So what are the compressor wheels? RT-650 utilizes the TD04L-16T and the RT-750 the TD04HL-19T. The air intake is 2.0 inches in diameter compared to 1.75 inche for stock. You will need to upgrade pipes to accommodate the larger diameter. The turbine features 9 blades. Lynx states this makes it lighter than 11 blade setups as well as offering higher theoretical flow. Ok, so what is the pricing? Here you go: To order, go here: Further questions can be answered by @Donvittorio on the forum. BimmerBoost looks forward to seeing results from members trying out this option.

    Plenty of discussion on BMW N54 intake manifolds but few independent testing results. Fab Factory's billet manifold is a work of art by itself but the question is can it provide a performance benefit? BimmerBoost member @martymil put it to the test in his BMW E82 1M. His results are below but also keep in mind he has upgraded N54 turbochargers. They are RB Classics: Thank you to @martymil for providing us our first back to back results, stock vs our N54 Port Injection Billet Intake Manifold on a 1M! First dyno is a direct swap of intake manifolds, absolutely NO changes except for intake manifolds: And with a few flash tweaks/minor retune: Logs attached in the OP

    A back and forth between Iroz Motorsport and APR is taking place on the EA888 2.0 liter MQB platform VW's. APR raised the bar with a new overall platform pass of 10.112 @ 142.76 last week in a front wheel drive MKVII Volkswagen GTI. Well, that record was broken and by quite a bit. It now stands at 9.580 @ 145.44. Incredible when you consider this was just done at the very slow Autoclub Dragway in Fontana at over 4000 feet of density altitude. Not a record breaking track and definitely not record breaking conditions. Yet, here we are. Iroz crushed their previous 10.2 second pass. Is this battle over? The IMS780 upgraded Golf R is able to put this power down thanks to all wheel drive with a Dodson upgraded dual clutch transmission. It will be hard for the record setting APR Stage III+ MKVII GTI to match the elapsed time. It certainly is incredible how well this platform is doing.

    You should be familiar with this F80 M3 as it holds the stock internal S55 platform 1/4 mile record. A very potent F80 as it runs 10.1 @ 139 in the 1/4 mile courtesy of its Pure Turbos Stage 2 upgrade. Stout but then again so is the competition it is facing in this video. There are a pair of Z06's in the video. The C7 is obviously blown from the factory and it features bolt ons. The C6 Z06 has an unnamed aftermarket blower. Both are said to be around 700 whp. The C6 pulls the C7 nicely. The next run after the Corvettes is the ZL1 LSA said to be around 700 whp. Well, the F80 M3 handles it without a problem. Next up is the C6 Z06. The M3 gets on the throttle quickly and it opens up a lead which is held. It looks like the C6 Z06 may have hit the limiter. They go again from a higher speed roll and it is a better run but the M3 still pulls and wins. This F80 is running very, very well. F80M3 Mods list: - Pureturbos Stage 2 - Precision Tuning Motorsports BEF - Burger Motorsports JB4 - FBO - DDS clutch pack - FULL WEIGHT - Race Fuel - Stock motor - Stock Fuel systems

    Tuning for the 991.2 generation Porsche 911 9A2 3.0 models is not coming easily. The ECU is posing problems and only GIAC is doing any sort of flash tuning at the moment. They require removing the ecu and they also have a price point of $2500. With limited flash tuning options piggybacks have a place in the market at least early on. DTE Systems in Germany offers a tuning box with the following claims: A 991.2 Carrera owner in Bangkok tested the DTE box out. His car has the full Fabspeed exhaust including headers as well as sport cats and an IPD plenum so it will make more power and torque than stock. The dyno type is a Dynocom which in our experience reads slightly higher than a Dynojet: Apologies for the tiny graph but in the top performance mode the DTE box picks up 33 wheel horsepower and 44 lb-ft of torque at the wheels. Modest gains but close enough to the claims by DTE. BoostAddict has a VR Tuning Box for the Project 991.2 Carrera that has yet to be installed. It is a different hardware unit than the DTE box without selectable modes. Vivid Racing also claims greater gains. Expect dyno testing in the next few weeks. Note: Ignore the Carrera S badging in the dyno video. The owner added it along with the exhaust tips to make it look like an S.

    The F85 X5 M has been on the market for a couple years now. As a matter of fact, Car and Driver already tested the SUV two years ago. Why are they testing it again? Who knows but the numbers are slightly different. Previously they pulled .96g on the skidpad with the 2015 model year car but the 2017 model year X5 M with Pilot Super Sports in 285/35/21 fronts and 325/30/21 rears seems to offer a bit more grip. Maybe that slight increase in grip explains the 12.2 elapsed time from the previous 12.3 and the 114 trap speed rather than 115. Without seeing all the data and the testing conditions who knows. These things vary day to day and run to run. The X5 M is still fat weighing ~5300 pounds. It is big, heavy, and incredibly quick and nimble for a German tank. Only some minor interior and I-drive changes take place for 2017. It is still the king of performance SUV's at least until the new Jeep Trackhawk arrives. Enjoy it while it is lasts BMW. VEHICLE TYPE:front-engine, all-wheel-drive, 5-passenger, 4-door hatchback PRICE AS TESTED:$111,195 (base price: $101,695) ENGINE TYPE:twin-turbocharged and intercooled DOHC 32-valve V-8, aluminum block and heads, direct fuel injection Displacement:268 cu in, 4395 cc Power: 567 hp @ 6500 rpm Torque: 553 lb-ft @ 2200 rpm TRANSMISSION:8-speed automatic with manual shifting mode DIMENSIONS: Wheelbase: 115.5 in Length: 192.7 in Width: 78.1 in Height: 67.6 in Passenger volume: 105 cu ft Cargo volume: 36 cu ft Curb weight: 5303 lb C/D TEST RESULTS: Zero to 60 mph: 3.8 sec Zero to 100 mph: 9.2 sec Zero to 130 mph: 16.7 sec Zero to 150 mph: 26.0 sec Rolling start, 5-60 mph: 4.5 sec Top gear, 30-50 mph: 2.6 sec Top gear, 50-70 mph: 3.0 sec Standing -mile: 12.2 sec @ 114 mph Top speed (governor limited, C/D est): 160 mph Braking, 70-0 mph: 153 ft Roadholding, 300-ft-dia skidpad: 0.98 g FUEL ECONOMY: EPA combined/city/highway: 16/14/19 mpg C/D observed: 16 mpg C/D observed 75-mph highway driving: 20 mpg C/D observed highway range: 440 mi

    Remember those people who were saying the Voodoo V8 would not lend itself well to boost due to its increased revs, displacement, and compression ratio compared to the Coyote V8? Send them a link a to this post. At 17.5 psi of boost this GT350 makes 1030 horses at the wheels. Torque is 797 lb-ft at the wheels. This is all courtesy of a Procharger F1A centrifugal blower. This is the highest horsepower stock internal Mustang GT350 Voodoo V8 in the world. Just jaw dropping numbers.

    A stout N54 here going up against some stout competition. The E92 335i has a Motiv single turbo N54 kit and said to be making roughly 720 horsepower at the wheels. This is a manual transmission example as well. The 335i takes on a blown C6 Z06 first. It is also said to have about 720 whp but the 335i pulls it up top each run. Next up is the twin turbo Boss 302 Coyote said to be at around 14 psi of boost. Who knows what the full specs are but the Mustang has no trouble with the BMW. There is a run with a missed gear but even when the 335i shifts correctly it's game over. The final run against a twin turbo Camaro SS is cut off when the Camaro starts to pull away for whatever reason.

    A Honda Civic Type for $34,775? Maybe if you are just really into Civics. For $60k? Maybe if you suffer from sort of mental disorder. Why some people think they can just flip any car for profit these days shows not only incredible greed but gullibility. Paying over sticker to get the first Ferrari 488 GTB or some rare exotic? Ok, fine, being first is part of the appeal. However, trying to get almost double the price for a Civic is just a joke. It is even worse than the guy who wanted $40k for his spot in the Dodge Demon line. If someone is stupid enough to pay huge markup on a Civic, frankly, they deserve the car.

    Porsche cutting costs and introducing turbochargers to the base 911 Carrera models creates a very interesting tuning opportunity. With the previous 991.1 generation 911 models one could not retrofit the X51 power kit from the Carrera S/GTS to the Carrera. Why? Because the S and GTS models utilized a naturally aspirated 3.8 liter flat-6 whereas the Carrera made due with a 3.4 liter unit. The X51 kit included new heads and cams that simply did not apply. They also did not provide much power for $18,5000 and the gains all came up top. With the 991.2 generation the Carrera, S, and GTS all share the same 9A2 3.0 engine. These specifications were previously detailed: 9A2 3.0 991.2 Carrera Horsepower: 370 Torque: 332 lb-ft Boost Pressure: 13.1 psi Bore x Stroke: 91mm x 76.4mm Redline: 7500 rpm Compression Ratio: 10.0:1 Intercooler: Air to Air Turbos: 49mm compressor/45mm turbine 9A2 3.0 991.2 Carrera S Horsepower: 420 Torque: 369 lb-ft Boost Pressure: 16.0 psi Bore x Stroke: 91mm x 76.4mm Redline: 7500 rpm Compression Ratio: 10.0:1 Intercooler: Air to Air Turbos: 51mm compressor/45mm turbine 9A2 3.0 991.2 Carrera GTS Horsepower: 450 Torque: 405 lb-ft Boost Pressure: 18.0 psi Bore x Stroke: 91mm x 76.4mm Redline: 7500 rpm Compression Ratio: 10.0:1 Intercooler: Air to Air Turbos: 55mm compressor/48mm turbine The hardware will work on any of the models as the engines are the exact same thing. Porsche just changes the turbos and software themselves. If you want the GTS turbochargers, Porsche will sell you them for $7500 along with the software to make them work and they back the power kit with the factory warranty. The only catch? You must have a 991.2 Carrera S. The Porsche dealer will not do the swap if you have a base car even though the turbos will obviously work. Why does Porsche do this? Because who is going to buy an S or a GTS if you can just order a base car for tens of thousands less and just add the turbos and software in? Well, that is why I opted for a base car. The problem is doing this swap without Porsche's blessing. After speaking with a Porsche dealer, they sternly said they will not do it. While the hardware will fit Porsche forces dealers to get their approval in Germany before whatever necessary software codes are released. You also need an S vin number. If you do this swap onto a base car you will lose your warranty and also will not have factory tuning software. Oh darn. PorscheBoost is going to try to make this swap happen. The part numbers will be available soon and a source stated the turbochargers alone from Germany can be had for roughly $3200 each. That means undercutting the hardware cost from Suncoast to $6400 rather than $7500. In theory, an aftermarket tune should be able to make the new hardware play nicely. The problem is that nobody has any real tuning solutions for different hardware. There may be enough leeway in the factory parameters to make it happen. Speaking with GIAC (the only company that has a flash tune for the platform) they said they have yet to read out a 991.2 GTS. A solution might be to try to flash the GTS software to a standard car. Maybe even an ECU swap will work. Either way, PorscheBoost will explore this option and report back after a meeting with GIAC. It is only a matter of time before you will be able to have 991.2 GTS hardware with far more tuning headroom on a base 991.2.

    A Mustang GT making 775 rear wheel horsepower on E85 courtesy of a Procharger at 14 psi is nothing to take lightly. Unless you happen to have an Arrow 9.0 liter stroked Gen V Dodge Viper V10 that also has upgraded heads and an aftermarket camshaft. The Viper is just brutal. It just takes off instantly and that is what you get with 9.0 liters of American muscle. A Procharger just will not offer that same instant throttle response and builds its torque toward redline. Just incredible how quick this naturally aspirated Viper is. The Viper is on NT05R tires and also has American Racing Headers, an underdrive pulley, and a titanium catback exhaust.

    An improvement of almost half a second from just changing the airbox on the 4.0 TFSI? Yep. Great results here from the Eventuri carbon fiber intake on an Audi C7 RS6 4.0 TFSI V8 which shows a considerable 60-130 improvement. Stock 60-130 MPH: 9.674 Eventuri 60-130 MPH: 9.274 That is with no other changes. Impressive for sure. Not to mention the airbox looks like a work of art. Pricing is not yet listed on the Eventuri website but AudiBoost will update this post with the cost.

    Here are the test results from Car and Driver for the new 2017 Honda Civic Type R. How does it do? Well, it is fairly light at 3111 pounds and for a front wheel drive handles quite well. It sticks to road as the skidpad shows 1.02g. The brakes are very good as well as the stopping power gets the car from 70 miles per hour to zero in 142 feet. Good braking feel, good handling, and overall a nimble package. The 306 horsepower turbocharged 2.0 liter engine provides pretty good performance. A 1/4 mile time of 13.5 @ 108 isn't much in this day and age but this is a front wheel drive Civic we're talking about. That will not put it ahead of its rivals in outright speed and it will not win a drag race against all wheel drive competition but from a roll it should put up a fight. As far as the styling, well, if you're really into boy racer Civics this is the perfect car for you. Anyone over 25 years old would probably feel like a tool getting out of it. Is it worth the $34,775? Maybe. It definitely isn't worth the $60k some people are trying to get for it.

    A hotter BMW F87 M2 model sporting the CS, CSL, or GTS moniker is expected next year. BMW continues to test an M2 on the Nurburgring and the speculation is that this car is sporting a revised BMW S55B30 powerplant from the F80 M3 and F82 M4 models. There may be some confusion as the M2 is expected to get a CS variant as well as a GTS/CSL variant. The detuned S55 engine rumors going into the F87 chassis started last year. Last month's article on all the upcoming BMW M models stated the M2 CS would get a 402 horsepower S55 engine. It seems everyone is just speculating and trying to get a scoop. Either way, a hotter M2 is coming for the 2018 model year.

    Porsche was expected to bring a hybrid system to the 911 with the 992 generation. That will not be happening. Why? Because of the added weight. Not to mention the added cost and complexity would push the 911 price into the stratosphere (as if it wasn't expensive to begin with). This may be a response to money troubles at VW but canceling a hybrid 911 is not a bad thing for enthusiasts. It will keep the weight and price down. The 992 is expected to be a little bit longer and wider. The engine will likely be pushed forward as well. That means better balance and handling. Will they be able to keep it light though? The target should be 31XX pounds for a manual 992. We will have to wait and see.

    VAG (Volkswagen Auto Group) is doing a fantastic job incorporating dual injection systems in performance cars. The Lamborghini Huracan and Audi R8 5.2 liter V10 for example feature both port and direct fuel injection systems. The same can be said for the new W12 Bentley motor. Well, the new 400 horsepower Audi 2.5 TFSI I5 also features a dual fuel injection system: This is great news for those who want to tune the MKIII Audi TT-RS and the upcoming Audi RS3 sedan. Motors featuring direct injection only run into fuel system issues pretty quickly when increasing power. Especially if using ethanol as fuel. What do most people do when they encounter fuel system limitations? They add injectors. In this case, Audi already did the work for you. The ECU will likely pose a problem but tuners will have it cracked quickly and once they do, the sky is the limit with the incredible 2.5 TFSI.

    Pretty good performance here although we expect more out of the car based on some acceleration videos posted. A 12.3 @ 115 in the 1/4 mile is respectable but this was done during the summer and the vehicle should be capable of breaking into the 11's with the all wheel drive. The owner mentioned a shifting issue: Maybe the quickest way to get it down the strip is to hit the shifts manually? We'll get a better idea as more owners take delivery but it is odd to hear about a shifting issue like this that was not present in the video linked in the beginning of the article.

    This is a bit of a shock. DTM racing in Germany is more competitive than ever because Audi, Mercedes, and BMW are all participating at the same time. While it is competitive how interesting is German Nascar? The cars have nothing at all to do with their street legal counterparts. Mercedes-AMG decided that rather than continue to race in DTM it makes more sense to focus on Formula E. This site agrees with them. Whether you like it or not electric drivetrains are the future and the technology trickle down will be helpful. The decision makes sense. Mercedes-AMG says they will continue to compete hard until the end of the 2018 season. The future of DTM is obviously greatly impacted by this move.

    Two twin turbo top mount German V8's here. Both have rear wheel drive configurations and both have dual clutch transmissions. The main difference is that the F13 BMW M6 has a larger 4.4 liter S63TU V8 compared to the AMG GT 4.0 liter M177. Oh, and the weight of course. The C190 AMG GT chassis weighs roughly 700 pounds less than the porky M6 and the AMG GT is no lightweight to begin with. The S63TU does gain more power tune only though and it shows. The AMG GT sports a Pure Turbos M177 turbo upgrade. It wins, but it should. It's lighter, has a turbo upgrade, and is slightly more expensive to begin with. Both cars are tuned by DME Tuning. If the M6 gets a solid turbo upgrade, it should have no problem with this AMG. P.S. To whomever recorded this, turn off the douchey music next time.

    Jaguar offers something different in the segment which is a supercharged V8. Their European rivals all feature turbocharged V8 powerplants. It is nice to have a different option but the reality is from a performance perspective Jaguar can not compete. Is 575 horsepower a lot? Not really in 2017 when you factor in that BMW, Mercedes, and Audi all pretty much sandbag their output. Plus, they offer much more torque. Jaguar's modest increase of 25 horsepower and 15 lb-ft of torque over the previous model year does not mean much of anything. The 516 lb-ft of torque are sent through a ZF 8-speed auto which is a very popular box these days. The 2018 XJR575 will not top an Audi S8 in straightline performance but perhaps Jaguar is looking for a buyer than wants something lighter and more nimble. At 41XX pounds the XJR not only undercuts the BMW 7, Audi A8, and Mercedes S-Class significantly it is even lighter than the mid-size offerings from the Germans. This may be the most fun to drive car in the class.

    Well, it is safe to say the Eaton TVS2300 based Magnuson Heartbeat Camaro SS LT1 supercharger system is provided a large performance boost. You may remember the Maguson Heartbeat kit at only 6 psi being good for a 10.8 @ 128.53 on a stock Camaro SS LT1. Well, turn up the boost with associated modifications and you can get into the 9's. They gave this Camaro upgraded injectors, an upgraded fuel pump, a meth injection kit, and race gas. It is still on the stock LT1 internals. Here is the result: Not bad at all. BoostAddict member @LesBaer is running this kit and has not reported any issues. A great way to significantly boost the performance of the Camaro SS.

    The Lexus LC 500 is a good looking car but a performance vehicle it is not. Lexus apparently is aiming to change that with an upcoming LC F model. Considering how hard Lexus is pushing the 'F' brand an LC F halo car make a lot of sense. What will they do to make it perform though? The LC is heavy at over 4300 pounds. The naturally aspirated V8 under the hood should have been put out to pasture years ago. What exactly are they planning on doing if a Nissan GTR is the target? Apparently 600 horsepower is in the works but we would have to guess forced induction will be necessary at that point. The Japanese site that started this rumor is saying a supercharger will provide boost. Our take? If you want GTR performance, buy a GTR. The odds of Lexus shaving off enough weight and getting enough power with a supercharger to make this thing perform on a high level are slim. Maybe it will end up being a nice alternative to a Mercedes-AMG S63 Coupe or BMW M though. Source

    Auto Express got their hands on these two new super sedans and decided to do a laptime comparison. Now, it is important note the Auto Express test track is tiny and seems to be go-kart sized. Not exactly a place for big and heavy sedans to really stretch their legs. We know the Panamera Turbo is very heavy from a recent test. 4593 pounds does not exactly lend itself to a nimble car. Still, Porsche does an admirable job hiding the weight and delivering superb handling. Auto Express does not weigh the cars (seriously? you call this testing?) but says the Mercedes W213 E63 AMG S is lighter. Well, how much lighter? Where is the weight? Does it have more on the nose? Both are all wheel drive but the Panamera Turbo is rated at less power and torque at 550 hp / 576 lb-ft . The Mercedes-AMG E63 S on the other hands is stated to make 603 horsepower and 627 lb-ft of torque. You would have to get them both on a dyno to know the true output. Laptimes: Panamera Turbo - 44.9 Mercedes-AMG E63 S - 44.6 Higher quality comparisons will come down the line but it is surprising to see the Mercedes take the win here.

    There's no shame in not being able to afford a Porsche. This owner of this Toyota RAV4 decided to embrace the idea. In all honesty though, if you have the means to pick up a 911, the vehicle is highly recommended.

    Some interesting exhaust testing here from Soul Performance Products showing the difference between HJS HD 200 cell sport catalytic converters with the PSE, cat bypass pipes with PSE, and their full three inch trackback exhaust. The testing took place at AWE-Tuning with their Mustang dynamometer. AWE-Tuning adjust their Mustang to read like a Dynojet so ignore the peak figures. Focus on the delta between the runs. Let's start with the sport cats with the factory PSE: Solid gains throughout the curve with just a catalytic converter change. Next up are cat bypass pipes: Slightly more torque and a top end power gain but really not enough to warrant going catless over catted. That is, unless you want more sound and to spend less money. Next up is a full straight pipe three inch Soul Performance Product exhaust: There is definitely power and torque to pick up in the exhaust if getting rid of the factory cats. Whether that be for sport cats or straight pipes is up to you.

    Remember the article last month about a grassroots (well, as grassroots as it gets for Viper owners) effort to get the Gen V Dodge Viper ACR on the Nurburgring? Well, the first time laptime for the group is in. The Dodge Viper ACR managed a lap in 7:03.45. Quick, definitely, but they did not break into the 6 minute range as expected. They hoped to top the Lamborghini Huracan Performante but they have a long way to go in order to beat a time of 6:52:01. The driver is Dominik Farnbacher. This is the man who ran a 7:12.13 'Ring time in the 4th generation Viper ACR. The team will likely try again as conditions have been rainy and they had limited running windows. This is essentially their first full go. We wish them the best of luck on subsequent attempts!

    I wish someone would go back and test the old fast cars from different generations with new tires like the PSS. The old published times and skidpad numbers are completely useless to compare to new cars on new rubber.
