    This maybe is not as crazy or complex as it first seems. Keep in mind that moving turbos closer and closer to the motor to minimize exhaust travel distance is something manufacturers are all doing in an effort to decrease lag. Most people are familiar with ITB's (Individual Throttle Bodies) which BMW M was famous for employing for quick throttle response. Individual turbochargers would be a whole new ballgame but the idea is similar in that you want to get as close to instant response as possible. You would in essence take very small turbochargers and fit them as close as you could to the cylinder head. The complexity and cost would likely go up and the odds of a turbo failure as well but there is no reason this can not work in theory. On a small three-cylinder it makes sense. As cylinders are added or engine configurations change it becomes much more difficult and expensive. As for a performance technology imagine the headache of a turbo upgrade or changing six turbos instead of one or two. Also keep in mind smaller turbochargers have less rotational mass which in theory also means aiding spool. We will believe it when we see it but a former Ford Engineer named Jim Clarke has filed a patent for the idea: Let's see a prototype.

    An N54 or 335 in the 10's is nothing new. It is new when it is a 335xi. Why haven't the all wheel drive models broken into the 10's if in theory it is easier for them to put their power down? Well, launches stress the drivetrain and the automatics struggle to cope with the power and torque. @Dave@Fuel-It! is the first to do it though with his E92 335xi with the following modifications: 2010 e92 335xi (daily driven for most part) - Pure Stage 2 High Flow Turbos - Fuel-It! DIY Platinum Port Injection w. Line upgrade & BT sensor/analyzer - Fuel-It! Stage 2 Bucketless LPFP - Burger Motorsports JB4 w. BT + OTS Hybrid PI BEF - TFT Inlet/Outlets - AR downpipes + AD-E 650 FMIC - APEX Arc-8 17x9 + Hankook Ventus v2 The Pure Stage 2 high flow turbos help make this possible and the Fuel-It! upgrades for the fuel system obviously play a big role. Are we going to see more xi's in the 10's? Are we going to see anyone really push the all wheel drive drivetrain? There are some 335xi's out there making some big numbers. Hopefully this is the first of many 10-second 335xi's.

    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.

    We all get carried away with big dyno numbers but they can come with big compromises in reliability especially in the BMW N54 world. A reliable ~600 wheel horsepower daily driver offers plenty of power and importantly won't break down or push the limit of the N54 internals. Here is the recipe from BMS: JB4, off the shelf E85 hybrid back end flash map Manual trans w/ steel flywheel and 335is/550 clutch Pure Stage2 turbos w/ silicon inlets Fuel-IT port injection rail and low pressure system BMS DCI, OCC, and other little bolt on modifications CPE intercooler Phoenix chargepipe w/ Tial valve Factory catback Factory motor Running ~E80 At 20psi (map7) it made ~530whp, ~24psi 600whp, ~25psi 615whp. Will an 800 wheel horsepower single turbo N54 be faster? Yes. Will it be more reliable? No. You can run this setup every day on a stock motor car. You can even push the turbos further but do you need to? Getting caught up in chasing numbers can have you doing that more than actually enjoying time behind the wheel.

    You might be saying to yourself, hold on, there are turbo upgrades out there for the BMW S55 engine. That is true but the upgrades are hybrid units which means they utilize the factory BMW S55 turbo housings. This upgrade from Kratos is a true full twin turbo upgrade. This turbo upgrade was hiding in the Motul booth at SEMA and it seems many people glossed over it as well as the implication for the platform. Currently, top S55's are pushing hybrids to the maximum. The truth that several tuners are not sharing is that the hybrids are pushed well out of their efficiency range to hit 7XX peak numbers. Some are even using nitrous to hit those figures. Pushing turbos out of their efficiency range may be fine for a glory pull or a couple passes but it is useless for someone on a roadcourse. Speaking of which, this upgrade has spent considerable time on the track for over a year on M4's that are raced professionally. You will not find any other turbo upgrade with that type of rigorous testing. There are some key points to focus on to truly understand the Kratos upgrade and how it differs: No core exchange required. You do not need to send in your factory S55 turbochargers. Keep them, sell them, etc. There is no wait time required as the turbochargers are in stock. Order, receive. That simple. Hybrid upgrades utilize stock journal bearing cartridges. The Kratos upgrade has a proprietary ball bearing design. Stainless investment castings are used from the CHRA bearing housings to the manifolds as opposed to cheaper sand castings. Inducer matched inlet piping for both turbochargers is included. If you are unfamiliar with the Kratos name do not worry as you will be hearing it a lot over the next few months. The brand will offer turbo upgrades engineered by ASR Engineering for a variety of platforms. This is just a teaser from SEMA but expect pricing information, dyno graphs, and further details to come shortly. The era of properly engineered true big twin upgrades for the S55 motor is finally here.

    This thing is absurd! APR announced their development of ECU tuning software for the new Audi 2.5 TFSI turbo I5 motor a couple weeks back. Well, that development is going very well as evidenced by this Stage I APR tuned 8V Audi RS3 sedan. Mid 10's? Tune only? Are you kidding me? APR got the car to run 10.55 @ 127.62 with just software alone. This is the quickest overall pass for the new 2.5 TFSI pass to date and they have yet to even begin pushing the thing! Absolutely incredible. Video is below. We are waiting on the slip from @Arin@APR.

    This conversion was actually completed a couple years ago yet it is surprising we are only getting run videos of it now. Whifbitz in the UK did this DCT transmission swap into a MKIV Toyota Supra and is controlling it with a Syvecs S6Plus ECU. Why a DCT swap? Well, they explain their reasoning here: The benefits are obvious but Whifbitz apparently is keeping all the information to themselves and if you want the swap you have to go through them. Their Supra is making about 700 horsepower and the gearbox is stock for now. They plan to add Dodson upgrades shortly. Adding a dual clutch to some older cars is a great way to give them a modern performance and comfort boost. Hopefully we see more of these DCT transmission swaps into various cars.

    Road and Track gets this right although there are some surprising results in the 2018 Performance Car of the Year competition. Giving the crown to the 720S despite it being bested on the track by not one but two cheaper cars will make this controversial. The damn thing is so fast though. Road and Track tested the 1/4 mile time for the 720S at 9.9 @ 148.2. This is another example of magazines showing numbers that are faster than reality. They get a 10.2 @ 134.6 for the Lamborghini Huracan Performante. What is amusing is that BoostAddict put up an article on both of these cars testing on the same dragstrip at the same time last month. The times? 9.98 @ 141.1 for the McLaren 720S and 10.78 @ 129.78 for the Lamborghini Huracan Performante. Something is off here especially when you look over the entire field and their acceleration results: 1. McLaren 720S - 9.9 @ 148.2 2. Lamborghini Huracan Performante - 10.2 @ 134.6 3. Mercedes-AMG GT R - 11.2 @ 128.9 4. Camaro ZL1 1LE - 11.7 @ 124.0 5. Bentley Continental Supersports - 11.7 @ 119.6 6. Alfa Romeo Giulia Quadrifoglio - 11.9 @ 119.7 7. Audi TT-RS - 11.9 @ 115.7 8. Lexus LC500 - 13.0 @ 111.8 9. Civic Type-R - 13.7 @ 106.3 10. 991.2 GT3 - NOT TESTED You have some times that are fast like for the McLaren and Lamborghini but then the new TT-RS only get a 115.7 trap speed. Iroz Motorsport got a 119 mile per hour trap speed out of the new TT-RS (with a downpipe) and an 11.4 elapsed time in Vegas heat. European magazines got a 121 trap speed stock. What is going on here? Do not take magazine times as gospel although forum racers will no doubt cite these numbers even especially blatantly obvious outliers like the Huran Performante. Acceleration is only one part of performance. What about the laptimes? Here you are, tested at NCM Motorsports Park: A 1:28.25 for the AMG GT R! The 720S despite being lighter and more powerful than either the AMG GT-R or Lamborghini Huracan Performante is bested by them. The AMG GT R is well over a full second quicker around the than the Huracan or 720S. That's huge! The AMG GT R is doing more with less. Mercedes-AMG deserves tremendous credit for what they achieved. A heavier front engine car is beating two lighter mid-engined exotics around the track that are almost twice its price. Remarkable! So why does the McLaren win? This: It seems to just be the best all around performance car in the world. You will not get an argument from BoostAddict. It is the best all around performance car in the world at any price. Source

    This E82 135i is doing some work! It belongs to Bimmerboost member @Newguy123 and he has the Pure Turbos Stage 2 N55 turbocharger. The car is a DCT which makes for quick shifts and it shows against the cars he runs. He was pushing roughly 22 psi of boost. Also note, it was fairly warm out at around 90 degrees. The first run is against a Procharged C5 which the 135i dispatches easily. A 900 hp Camaro is next and the 135i gets a lead but the Camaro starts to come on up top. A 700 whp E82 135i automatic is next. It seems to get a jump and it pulls. Definitely a fast 135i. Next we have a supercharged E92 M3. It gets pulled rather easily. A Motiv built motor single turbo E92 335i N54 is next. It is said to be pushing 17 psi of boost. Time to turn up the boost. LS7 power is next. The C7 Z06 is naturally aspirated but is making 575 whp with a heads and cam upgrade. It's a good run between the two with the 135i gaining some ground on a shift at one point which it holds. How about a C7 Z06? It is claimed to be making 750 horsepower. Somehow that power doesn't transfer to the run. Another Pure Stage 2 upgraded E82 135i N55 lines up. It is also a DCT but boost is at 18 psi. This shows the difference those extra 4 psi make. There is a re-run with the 900 hp Camaro not worth mentioning. The final run is against Pure Turbos 750 whp Civic. Getting spanked by a Civic can not feel good. Great runs all around a very quick 135i.

    Huge numbers here out of a BMW F10 550i with the Pure Turbos Stage 1 N63TU turbocharger upgrade. Keep in mind the graph you are about to see is from a Mustang dyno meaning this is easily a 700+ rwhp car on a Dynojet. That also means it will eat a stock F10 M5 for lunch. Compare the stock output to upgraded turbo and meth tuned numbers: It's a night and day difference. The N63TU is an awesome value with a turbo upgrade. Keep in mind this is just scratching the surface. A Pure Stage II or larger turbo upgrade should produce much more power but the transmission will no doubt become a concern and upgrades for the automatic are much harder to come by than the M5 DCT. Awesome numbers.

    Less is more. That is how Porsche is marketing the 911 Carrera T. They are right. This entry level 911 adds a few options not available on the standard 991.2 Carrera and also strips out some weight by eliminating a few bells and whistles. 44 pounds are shaved off. How? The glass is thinner, cloth door loops replace handles, less sound deadening, rear seats are deleted, and the PCM (Porsche Communications Management) system is removed. That is a lot to ditch for seemingly only 44 pounds less weight. You can also at no additional cost add in the PCM system and the rear seats. Ok, it's lighter, but what else? The sport chassis PASM system which is available on the S and standard on the GTS is standard on the 911 T. Rear axle steering which is not available as an option on the Carrera but is for the S is also available now as an option for the 911 T. The manual transmission also gets shorter gear ratios. Oh, and don't forget the mechanically locking rear differential. The engine remains unchanged but the engine was never an issue and more power is there in the aftermarket should one want or even need it. Porsche took the Carrera and made it sharper and lighter. This is the best value in the 911 lineup when it comes to a driver's 911. As the owner of a 991.2 Carrera, suffice it to say, I'm pissed off. The 911 T is superb and everything I want the car to be. Less is more – the new Porsche 911 Carrera TA puristic addition to the 911 family Stuttgart . With the 911 Carrera T, Porsche is reviving the puristic concept behind the 911 T of 1968: less weight, shorter transmission ratios from the manual gearbox and rear-wheel drive with mechanical rear differential lock for an enhanced performance and intense driving pleasure. The new model’s unique appearance is based on the 911 Carrera and its engine delivers 272 kW (370 hp). The 911 Carrera T – at Porsche, “T” stands for Touring – also boasts several other equipment features that are not available for the 911 Carrera, including the PASM sports chassis as standard, lowered by 20 mm, the weight-optimised Sport Chrono Package, a shortened shift lever with red shift pattern and Sport-Tex seat centres. The rear-axle steering, which is not available for the 911 Carrera, is available as an option for the 911 Carrera T. Every aspect of the equipment in the 911 Carrera T is designed to optimise sportiness and deliver lightweight construction: The rear window and rear side windows are made from lightweight glass and the door trims feature opening loops. The sound absorption has been largely reduced. The rear seats have been omitted along with the Porsche Communication Management (PCM), though both are still available on request at no additional cost. The result of the lightweight construction measures: At an unladen weight of 1,425 kilograms, the two-seater is 20 kilograms lighter than a 911 Carrera with comparable equipment. The 911 Carrera T will be available from January 2018 and can be pre-ordered now. In Germany, the price will be EUR 107,553 including VAT and country-specific features. A sporty design and unique appearance The design of the 911 Carrera T highlights the emotionality and sportiness of the coupé with rear-axle transmission. The body parts and wheels function as clear differentiating elements. At the front, the 911 Carrera T features an aerodynamically optimised front spoiler lip, and the Sport Design exterior mirrors are painted in Agate Grey Metallic. From the side, the new model is easily recognisable thanks to its 20-inch Carrera S wheels in Titan Grey. The “911 Carrera T” logos represent another distinctive feature at the side. The rear view is characterised by the slats in the rear lid grille, the Porsche logo, the “911 Carrera T” model designation in Agate Grey and the sports exhaust system provided as standard, with centrally positioned tailpipes painted in black. The exterior colour options are Black, Lava Orange, Guards Red, Racing Yellow, White and Miami Blue, as well as the metallic colours Carrara White, Jet Black and GT Silver. A puristic interior concept and new interior package The appearance of the passenger compartment also has a sporty and puristic emphasis. The driver enjoys black, four-way, electric sports seats with a seat centre in Sport-Tex fabric, while the headrests feature a “911” logo stitched in black. This new Carrera T model also comes with the option to choose full bucket seats for the first time. Steering actions are completed via the GT sports steering wheel with leather rim, and the mode switch provided on the steering wheel as standard allows the driver to select different driving programmes. The shortened shift lever with shift pattern in red remains exclusive to the 911 Carrera T. The decorative trims on the dashboard and doors are black, as are the door opening loops. A new addition is the T interior package, which creates an even sportier look with the contrasting colours of Racing Yellow, Guards Red or GT Silver. These colours can be used to add visual accents on various interior components, such as the seat belts, the “911” logo on the headrests, the door opening loops or the centres of the Sport-Tex seats. Improved weight-to-power ratio plus enhanced performance The six-cylinder flat engine with a displacement of three litres and twin turbocharging generates an output of 272 kW (370 hp) and a maximum torque of 450 Nm, delivering between 1,750 rpm and 5,000 rpm. The weight-to-power ratio has been improved to 3.85 kg/hp, ensuring enhanced performance and more agile driving dynamics. Thanks to a shorter rear axle ratio and mechanical differential lock, the 911 Carrera T can sprint from zero to 100 km/h in 4.5 seconds – 0.1 seconds faster than the 911 Carrera Coupé. The model reaches the 200-km/h limit in just 15.1 seconds. Porsche Doppelkupplung (PDK) is also available as an option on the Carrera T, enabling the vehicle to reach 100 km/h in 4.2 seconds, and 200 km/h in 14.5 seconds. Both transmission variants enable a top speed of over 290 km/h.

    It is often amusing to see after a crack for an ECU is announced it then spreads out like wildfire. B&C Consulting offers tuning for the 2017 on Porsche 911 (991.2) 9A2B6 3.0 models now having access to the SDI21 ECU much like Autotuner. Whereas Autotuner sells the master system to tune these ECU's to tuners B&C offers tunes and dyno'd the cars. No, this is not an OBD-II tune: This is a bench flash and the ECU must be removed. It is not too terrible of a process and will put up a DIY on removing the ECU later this week: The dynos are where things get interesting. Unfortunately, they are crank corrected: The crank rating for the 991.2 models is underrated so keep that in mind when viewing the graphs. What we learn is that the GTS is easily clearing 500 horsepower with a Stage I tune. We would expect it to be a 500+ whp car on a Dynojet with bolt ons on pump gas. The Carrera shows much larger gains from stock to tuned. That is because it is not pushed nearly as hard with only 13.1 psi of boost stock. The GTS is in a higher state of tune and its turbos are definitely being pushed more off the showroom floor. A 991.2 Carrera with a tune should have no trouble dispatching a stock 991.2 GTS. It likely will nip at a 997.1 Turbo's heels. If one were to guess, it should trap roughly 124 miles per hour and be on the verge of that 10 second barrier. A bargain in the Porsche 911 world, definitely. As these tunes get out there and more people dyno we will have a better idea. This is just the beginning but 991.2 3.0 models are about to become very stout, very quickly.

    That is more like it! Very nice to see the S65 V8 strut its stuff with a quality ethanol tune. This record was made possible by RK-Tunes and their E85 tuning for the E92 M3's V8. Who would have thought the car was capable of mid 11's naturally aspirated? Here is the full mod list: RK-Tunes E85 File Macht Schnell Stage 2 Intake Macht Schnell Pulleys Gintani XPipe Akrapovic Exhaust Volk TE-37's Toyo R888R Rear Seats and Passenger seat removed There is even a bit of room to improve here on the 1.798 60 foot: Maybe an 11.3X is in there in cooler weather? We'll see. Congratulations to @SalM on the new overall quickest and fastest naturally aspirated E9X M3 record.

    You should be familiar with the various BMW engine swaps Awron helps facilitate with their electronics. If not, here's a quick refresher. They have a swap kit for the BMW N54 engine and as well as the N63/S63 twin turbo V8 motors. Well, add an S85 swap kit to the list and if you want BimmerBoost's opinion (of course you do) putting an M V10 under the hood of a BMW is the coolest engine swap that can be done. For example, remember when someone put an S85 under the hood of a Z3 coupe? They basically made a German Viper. As for what this kit costs Awron did not provide that info. Additionally, it seems you may need to use a digital gauge cluster for this to work but it is Plug and Play with what they give you. Now who wants to put an S85 under the hood of a Z8? The engine electronics package has the following properties: Motor control fully OBD, EOBD diagnostic capability DSC disabled Secondary air system disabled Adapted configuration diagnostic ECU network on autonomous use Disabled engine diagnostic probes and function Configuration manual Oil pump fully functional for lateral acceleration Sport button is disabled (can be installed and configured to customer requirements) With this engine package you can take any S85 engine in operation, regardless of where it is installed. Based on the series software, we have developed software that allows the engine no longer has to rely on the complete electrical system. He jumps in all conditions and runs like a train engine. The kit is designed so that it provides you the opportunity to incorporate this in various BMW models and connected to the existing electrical system.

    Dyno results for the 991.2 generation Porsche 911's with the 9A2B6 3.0 twin turbo flat-6 are somewhat hard to come by. Fortunately, BoostAddict member @///M3THOD put his 991.2 Carrera S PDK on the Topspeed Motorsports Dynojet. His car is stock other than the Fabspeed cat bypass pipes. The problem though is he did not get a baseline: 416 horsepower and 412 lb-ft of torque at the wheels is very healthy for just cat bypass pipes especially when the car is rated at 420 at the crank. The turbo 9A2 3.0 engines are underrated. What does a stock 991.2 Carrera S look like on a Dynojet? Well, GIAC claims on the Champion Motorsport Dynojet that the car dynos 372 to the wheels. Additionally, Cobb released a graph showing 382 whp on a Dynojet. The baseline ranges look very similar. Are cat bypass pipes alone picking up 30+ whp? Well, the only way to find out is for the project car to test the pipes and do a baseline overlay. We are waiting for @Soul Performance Products to get back to us regarding a sale of bypass pipes.

    Something is off here. Ok, first of all, Car and Driver's test result for the new Hellcat supercharged 2018 Jeep Grand Cherokee Trackhawk is not slow per se but it is much slower than expected. A 12.0 @ 115 in the 1/4 mile? Sure that puts it ahead of almost every other SUV out there short of the 2017 Bentley Bentayga but how in the world is a heavier Bentley with less power running a faster 12.0 @ 117 1/4 mile time? A Challenger and Charger Hellcat will hit 126 miles per hour in the 1/4 mile. The boats weigh 4500+ pounds. The Cherokee Trackhawk comes in at roughly 700 pounds more with the tested 5258 pound curb weight. The Trackhawk should be trapping ~120 miles per hour not 115. A 567 horsepower BMW F85 X5M runs 12.2 @ 114. Even Mopar themselves said it would do high 11's at 116 and that should be conservative. What is going on here? Maybe this is a fluke? Maybe something was wrong with the Trackhawk? Where is the 707 horsepower? This SUV should be annihilating everything else on the market especially the Bentayga and X5M. Disappointing to say the least.

    This is something different and admittedly cool. You no doubt have seen people do raised white letters on tires. Pirelli is allowing customers to choose whatever color they want to accent their P Zero Color Edition tires. How does it work? You go into the Pirelli configurator and select your car: Then, you personalize the colors. Here are a few examples: Just another way to customize and set yourself apart. Good thinking on the part of Pirelli and there should be some interesting combos as more people try the Color Edition tires out.

    Well, that was fast. The new W213 Mercedes-AMG E63 S is already being tuned in the US. Renntech was the very first to show ecu tuning results getting the car over 700 horsepower at the crank. DME Tuning has some Dynojet results at the wheels to share. This is on 93 octane pump gas, tune only: 656 horsepower and 711 lb-ft of torque at the wheels. Those worried about the smaller 4.0 liter M177 not offering torque compared to the M157 can let those fears go. Now, yes, the W213 is all wheel drive but DME Tuning was not able to dyno it in all wheel drive mode so they set it to rear wheel drive to get the numbers. What about the baseline? That was not provided but DME Tuning stated they would flash back to stock and send BenzBoost the baseline. Certainly stout though, isn't it?

    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.

    Kline Innovation is located in Romania. They do some great exhaust work and their latest release is for the Porsche 991.2 Carrera models with the 9A2 3.0 engine. Their system includes 100 or 200 cell cats as well as a cat-bypass option. Equal length manifolds 100/200cell HJS cat pipes Test pipes Rear valvetronic system Carbon tips It is available in Inconel 304 grade stainless steel. The Inconel is roughly 22 pounds lighter: It looks great and it sounds even better in the video below. Why no dyno graphs though? A full race system with equal length manifolds should produce some very impressive gains. There is not a lot of manifold data out there for the 9A2 motor so hopefully someone tests it out. Definitely a nice option to have on the market.

    A recent article on future motors possibly downsizing and going to individual turbos per cylinder prompted further research and the idea was done back in 2006. Owen Developments based in the UK decided to make it reality. They did not provide many details though. Horsepower? Nope. Torque? Nope? Dyno? Nope. Video of it running? Nope. Basically if you Google hard enough you'll come across a few pictures and that is about it. This is not exactly the design that BoostAddict discussed though. While this is indeed a turbo per cylinder the idea is to go with very small turbos fit almost inside the head for maximum spool. It is nice to see people experiment but thus far there seems to be little practical application.

    It was just a matter of time but let's all congratulate Maximum PSI on setting the overall S55 platform world record! As you likely recall TPG Tuning was the first in the 9's with a 9.987 @ 143.63 pass in the 1/4 mile. Maximum PSI joins them now in the 9's but set a new overall platform record in the process with a 9.827 @ 145.58 pass. That makes for the quickest and fastest F80 M3 and S55 powered BMW. They also did more than one record pass: The specs? - Build motor by #maximumpsi - PureTurbos Stage 2 - Upgraded fuel systems by Fuel-It! - BEF/tuned by HCP - Flash tool by PTF Bootmod3 - Intercooler/ intake/ PI by EOS - Upgraded clutches by Dodson - BMS JB4 After their last 10.0 pass we knew it was just a matter of time. Congratulations to Maximum PSI!

    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.

    The Porsche 991.2 models equipped with the 9A2B6 3.0 twin turbocharged flat-6 engine have a Start/Stop function like many modern cars designed to improve fuel economy. This system can be disabled but those using it should be aware of potential premature wear issues. Take a look at this turbine shaft off a 991.2 Carrera with only 4000 miles. Yes, 4000 not 40,000. The turbine shaft shows bearing contact. Definitely more wear than expected on a car with such low mileage. The theory is that the loss of oil pressure during a stop lets the shaft move and contact the journal bearing. Is this a problem? Perhaps. It depends how long one keeps the car and how it is driven. One way to make sure there will not be a future problem is to switch to ball bearing turbochargers. Either way, Porsche is building cars designed to just make it through the warranty period these days like everyone else. It will be interesting to see if there are turbo failures in higher mileage cars. Disabling the Start/Stop feature when driving may be prudent for 991.2 owners as well. Photo Credit: Mimo Technik

    This is huge news but lets tempter expectations until it is actually tested out. Autotuner in Europe claims the Continental/Siemens SDI21 ECU that has been giving Porsche tuners so much trouble has finally been cracked with read and write access. Here is what they had to say: They e-mailed BoostAddict with further details: No dynos provided but they are right that there is big interest here. Keep in mind this affects not only the 9A2B6 motor in the 991.2 Carrera lineup but the 991.2 Turbo and S models as well as the 9A2B4 engines for the 718 models. What is interesting to note is another tuner contacted BoostAddict this morning asking for access to the PorscheBoost Project 991.2 for tuning purposes. It seems a crack has filtered out. Gentlemen, let the tuning begin!

    Don't like the idea of methanol injection in your motor? Well, maybe this will change your mind. This E60 535i belongs to BimmerBoost member @ParksDetailing and he recently got a methanol tune. You may remember his car previously making 498 whp on 93 octane pump gas. What a difference a new tune, two more psi, and meth injection makes, eh? He is now making just short of 600 whp: You will notice this was all picked up past 4500 rpm meaning the top end is much, much stronger now. CES Motorsport explains why here: E85 is obviously highly desirable but not everyone has E85 pumps available plus it quickly taxes a fuel system. Methanol actually does the opposite in making a fuel system more robust in power capability as well not taking a huge toll on mileage. The modifications for this car as the same before except now with a meth kit and new tune: - PureTurbos Stage 2 - FBO - Meth kit - MHD BEF - BMS jb4 - Eurompire_official LPFP - Stock 6 speed - RB inlets - AR Downpipes - ER Intercooler - Dinan Exhaust

    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.

    Several tuners are already pushing the new W213 generation E63 S with its 4.0 liter twin turbocharged M177 V8 and the results are impressive. Tuner PP-P Performance is showing a dyno of 734 horsepower at the crank. That is with their ECU flash tune and catless downpipes. Putting these numbers in context is somewhat difficult as their MAHA dynamometer reads very differently. The wheel output figure shows 564 whp: Far more conservative than the 656 wheel horsepower DME Tuning showed on their all wheel drive Dynojet with a Stage I tune. Hopefully we will get more dyno tests for contextual purposes but the new W213 E63 is already a tuner's dream.

    We are going to see a 10-second tune only F80 M3 or F82 M4 at some point. This is an absolutely incredible result when you factor in the BMW F82 M4 is running only Stage I VF-Engineering S55 Hex tuning software and is on 93 octane pump gas. It is full weight as well and on street tires. Just a realistic result that is repeatable every day. On drag rubber that 1.736 60 foot could come down a bit as the 11.008 @ 126.02 pass is achingly close to breaking into the 10's. Eight thousandths of a second? Maybe all the driver needs to do is go to the bathroom and then try again. This is the quickest software only pass to date. Phenomenal!

    This is essentially M7 vs. M3. Why? Because while BMW for whatever reason refuses to badge a 7-Series as a real M car the M760Li might as well be that car. With all wheel drive and a twin turbo 6.6 liter V12 producing 600 horsepower and 590 lb-ft of torque it follows BMW M's current recipe of equating M models with massive straight line power. Straight line power being exactly what the M760Li offers. From a stop, this is not much of a race. The rear wheel drive M3 can not hook up as well and gets smoked. The M760 runs an 11.3 compared to the M3's 12.3. Clearly a result influenced by a lack of traction and Carwow does not include trap speeds because they suck at this. They run from a roll which should eliminate the traction variable but the utter stupidity of leaving the cars in auto mode (especially the M3 with its smaller motor) when they should be in the right gear for the start speed is beyond words. It's pretty close from a roll. If the M3 driver was in the right gear instead of waiting for the transmission to kickdown into the proper gear it might be door to door. The M760Li wins by virtue of torque and the M3 is saddled down with extra passengers which are a greater detriment to it than the M760Li. What we learn is the top of the line 7-Series is mean from a stop and that Carwow still doesn't know how to do a proper comparison.
