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

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

    According to Car and Driver's Porsche 991.2 GTS test results it is right there with Porsche 991.1 Turbo models. Actually, the 125 mile per hour trap speed is faster than the 123 MotorTrend got for the 991.1 Turbo but the 991.1 Turbo is known for being inconsistent. The 991.2 GTS model certainly is impressive and those larger turbochargers are doing some serious work. Realistically, expect 122-123 on the dragstrip based on the 991.2 Carrera S running 11.5 @ 120. An all wheel drive GTS likely will be knocking right on that 10-second door in stock form. Now imagine it with a tune... easy mid-10's? High 12X traps? The car is not just about acceleration obviously although clearly it is overachieving for 450 horsepower. The curb weight is fairly light at 3335 pounds and the handling plus steering feedback is stated as phenomenal. Honestly, it is hard to argue against the 911 GTS as the best sports car in the world produced today for the money. They're not wrong. VEHICLE TYPE: rear-engine, rear-wheel-drive, 2+2-passenger, 2-door coupe PRICE AS TESTED: $129,560 (base price: $123,770) ENGINE TYPE: twin-turbocharged and intercooled DOHC 24-valve flat-6, aluminum block and heads, direct fuel injection DISPLACEMENT: 182 cu in, 2981 cc POWER: 450 hp @ 6500 rpm TORQUE: 405 lb-ft @ 2150 rpm TRANSMISSION: 7-speed dual-clutch automatic with manual shifting mode DIMENSIONS: WHEELBASE: 96.5 in LENGTH: 178.3 in WIDTH: 72.9 in HEIGHT: 50.6 in PASSENGER VOLUME: 70 cu ft CARGO VOLUME: 5 cu ft CURB WEIGHT: 3335 lb C/D TEST RESULTS: Zero to 60 mph: 3.0 sec Zero to 100 mph: 7.2 sec Zero to 130 mph: 12.2 sec Zero to 150 mph: 17.4 sec Rolling start, 5-60 mph: 3.8 sec Top gear, 30-50 mph: 2.4 sec Top gear, 50-70 mph: 2.5 sec Standing ¼-mile: 11.3 sec @ 125 mph Top speed (drag limited, mfr's claim): 193 mph Braking, 70-0 mph: 142 ft Roadholding, 300-ft-dia skidpad: 1.05 g C/D FUEL ECONOMY: Observed: 20 mpg EPA FUEL ECONOMY: Combined/city/highway: 23/20/26 mpg

    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!

    TPG Tuning is certainly not resting on their laurels. You know their achievements in the F80 M3 and F82 M4 S55 tuning sphere well. They were the first to break into the 9's on the platform but recently Maximum PSI took the quickest and fastest overall record. Well, considering this teaser from TPG Tuning they are gunning to take the title back: That 857 wheel horsepower is on a Mustang dyno meaning this car is well over 900 to the tires on a Dynojet. The 908 lb-ft of torque at the wheels is just absurd. How are they hitting this when they already maxed out their hybrid turbos a while ago? Nitrous. TPG Tuning says this is on a 150 shot and that amount can go up or down depending on the jets and how the nitrous system is set up. Expect the S55 overall record to be broken, easily.

    The new 991.2 generation GT2 RS is the baddest Porsche 911 ever produced. With 700 horsepower from its twin turbo 3.8 liter powerplant it accelerates very, very quickly. That is despite its tremendous aerodynamic drag from the downforce generated which helps it set Nurburgring lap records. Sport Auto took the car out on the autobahn to do a launch control initiated top speed run. They hit an indicated 356 kph which is 221 mph. Their GPS system though shows 342 kph which is 212.5 miles per hour. Interestingly, Porsche says the GT2 RS top speed is 211 miles per hour and that appears to be spot on based on this video and the GPS testing. The Porsche speedometer reads high just like most cars. It will be interesting to see what the GT2 RS puts down on the dyno. 650 wheel horsepower on a Dynojet is our guess.

    Somewhat glossed over in the news that the 991.2 SDI21 ECU was cracked is that this led to ECU tuning also opening up for the 9A2B4 2.0 and 2.5 motors in the Porsche 718 models. What kind of power are we looking at for a Stage I tune for a 718 Boxster or Cayman S? Roughly 430 horsepower at the crank: An increase of 80 horsepower but that torque curve is questionable. Why it is spooling later tuned is anyone's guess but there is a ton more area under the curve from 3000 rpm until redline. How does this stack up to say a tuned 991.2 Carrera GTS? The tuned 718 S makes roughly 100 less horsepower. Another way to look at it is making almost stock 991.2 GTS horsepower. That should result in slightly over 400 rwhp on a Dynojet. That makes for quite a Porsche performance bargain and the 718 GTS model with its larger turbo will make even more power when tuned. It is a good time to be a Porsche enthusiast at any area of the model spectrum.

    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.

    Great numbers here out of a bolt on F80 M3. What makes the result particularly impressive is that this BMW F80 M3 is on the factory S55 fuel system and the factory turbochargers of course. The tuning is a big factor and this is a custom E85 tune by someone called @carythelabelguy whomever he is. The tune is through the Pro Tuning Freaks Bootmod3 platform. Check out the Dynapack results: That AutoTalent Dynapack from the graphs BimmerBoost has viewed tends to read high compared to a Dynojet. Still, 577.7 wheel horsepower and 562.7 lb-ft of torque at the wheels is nothing to sneeze at. Excellent numbers and a stout M3 for bolt ons and an E85 tune.

    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.

    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.

    ETS (Extreme Turbo Systems) is best known for their Nissan GTR work but they cover a variety of platforms. That includes the Lamborghini Huracan and ETS may just offer the best value when it comes to Huracan twin turbo kits. Their base twin turbo kit retails for $24,995.00. That is cheaper than, well, anyone else. How are they offering a twin turbo kit for what you can say is a relative bargain on the platform? They do not include tuning. Let's go over the specs: ETS Lamborghini Huracan Turbo Kit Twin PT6266 Gen 2 Turbochargers (Default) Twin 60mm TiAL wastegates ETS 4.0" stainless steel speed density intakes ETS 3.5" stainless steel exhaust system w/ recirculated dump tubes Breeze vband clamps for the exhaust system ETS braided oil feed lines ETS braided oil drain lines Modular Turbo Kit System At anytime you can upgrade your turbochargers for more power! PT6466 - 1500whp+ PT6870 - 1600whp+ PT7275 - 1800whp+ PT7675 - 2000whp+ ETS Water/Air Intercooler Kit ETS Water/Air Intercooler ETS Water/Air Ice Box Dual ETS Water/Air Rear Heat Exchanger Dual ETS Water/Air Front Heat Exchanger High flow water pump Twin 50mm TiAL blow off valves ETS high temp 4ply silicone couplers Breeze t-bolt clamps for intercooler piping ETS braided water lines Performance Stock Motor Pump Gas - 800whp+ Race Gas - 1000whp+ Built Motor Pump Gas - 1000whp+ depending on turbocharger size. Race Gas - 1800whp+ depending on turbocharger size. Tuning We recommend using a Syvecs PNP Engine Management System. The output will range based on if the kit is used on a stock motor, with race gas, built motor, and the quality of the tuning. They recommend using the Syvecs standalone Plug and Play system. Definitely a good choice but not cheap. Tuning on the factory DME is an option but you will need a high quality tuner to pull it off and for it to be reliable/safe. It will be great to see some results with this kit and what the buyers utilize for tuning.

    Now that the troublesome 991.2 SDI21 ECU is cracked tuning is commencing from a variety of sources. Those sources for the most part are European for now as the crack originated in Europe. Mcchip-DKR is one of those European sources tuning the 9A2B6 3.0 motor and they got a 991.2 GTS on their SuperFlow dyno. Mcchip-DKR previously did not release graphs for their 991.2 tuning claims so it is great to see actual dyno results from them on the platform: The GTS model obviously has larger turbos and comes in a higher state of tune compared to the S and base 991.2's. It still has plenty of headroom though as illustrated. They are getting another 80 horsepower and according to the graph 100 lb-ft of torque or so. The peak torque figure posted is 481 lb-ft but the delta is what we are focusing on. We will need to see these cars on American dynos for further context but rest assured there is plenty to gain with the 991.2 GTS turbochargers over the factory output.
