    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.

    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.

    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.

    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

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    Gintani is still tuning the project 991.2. This is a preliminary graph that gives you an idea of the difference the tune makes. Gintani believes they can add a little bit of power up top but as you can see this motor is a torque monster down low. Compared to GIAC's 91 octane tune Gintani does not ramp in the torque as hard down low but the peak comes at about 4200 rpm compared to 2950 giving a broader curve: The torque increase is 110 lb-ft over the baseline but for whatever reason the baseline is a bit lower than it was on other Mustang dynamometers while the peak horsepower is right on the money. The dyno was recently calibrated. Gintani is still tuning so take this as an early result but obviously there is a lot on tap from the stock 991.2 Carrera. Additionally, dyno results with cat bypass pipes from Soul Performance should come today and Gintani also plans to do a race gas tune which thus far nobody has done.

    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.

    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!

    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!

    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

    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.

    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

    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.

    You may remember an article from last month where a 720S and a supercharged Huracan race. BoostAddict called it out as a worthless 'Amateur Hour' comparison as it was skewed to give the Huracan the appearance of being the faster car. Frankly, the video insulted everyone's intelligence. The cars are compared again and this time rather than short bursts on the street where the Huracan jumps and then proclaims victory there are some proper rolling runs that allow the cars to stretch their legs. Be warned, you have to sit through a bunch of bullshit before getting to the actual runs. For some reason the guy making the first video below thinks people care about him getting sick. Nobody cares. Skip the 6:55 mark to get a real roll race or just watch the DragTimes edit below it. The Huracan gets a jump and the positive displacement blower certainly gives it an advantage down low. The McLaren 720S easily catches up though and just blasts by it. Run after run shows it really is no contest

    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.

    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.
