    The rotating assembly in the BMW M S65 V8 and S85 V10 motors was tested by BMW to 10k rpm. That does not mean the car will continue to make power to 10k rpm only that it is designed to withstand high rpm stress. MRF Engineering is taking a 4.2 liter S65 they built to 9000 rpm and they claim a naturally aspirated record as well. The problem is their video shows them going to 8650 rpm and they state they hit 8950 in further tuning. Furthermore, there are no dyno results to show the curve. 9k rpm on the S65 is actually nothing new. Xcede in South Africa hit 8800 rpm way back in 2010 and Evolve routinely revved out to ~8800 rpm as well. The difference is with Schrick cams widely available now building a high revving S65 V8 that makes power past 9000 rpm should be possible. That is what we are hoping to see from MRF Engineering but we will have to wait until they post a dyno proving it. <blockquote class="instagram-media" data-instgrm-version="7" style=" background:#FFF; border:0; border-radius:3px; box-shadow:0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width:658px; padding:0; width:99.375%; width:-webkit-calc(100% - 2px); width:calc(100% - 2px);"><div style="padding:8px;"> <div style=" background:#F8F8F8; line-height:0; margin-top:40px; padding:50.0% 0; text-align:center; width:100%;"> <div style=" background:url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAACwAAAAsCAMAAAApWqozAAAABGdBTUEAALGPC/xhBQAAAAFzUkdCAK7OHOkAAAAMUExURczMzPf399fX1+bm5mzY9AMAAADiSURBVDjLvZXbEsMgCES5/P8/t9FuRVCRmU73JWlzosgSIIZURCjo/ad+EQJJB4Hv8BFt+IDpQoCx1wjOSBFhh2XssxEIYn3ulI/6MNReE07UIWJEv8UEOWDS88LY97kqyTliJKKtuYBbruAyVh5wOHiXmpi5we58Ek028czwyuQdLKPG1Bkb4NnM+VeAnfHqn1k4+GPT6uGQcvu2h2OVuIf/gWUFyy8OWEpdyZSa3aVCqpVoVvzZZ2VTnn2wU8qzVjDDetO90GSy9mVLqtgYSy231MxrY6I2gGqjrTY0L8fxCxfCBbhWrsYYAAAAAElFTkSuQmCC); display:block; height:44px; margin:0 auto -44px; position:relative; top:-22px; width:44px;"></div></div><p style=" color:#c9c8cd; font-family:Arial,sans-serif; font-size:14px; line-height:17px; margin-bottom:0; margin-top:8px; overflow:hidden; padding:8px 0 7px; text-align:center; text-overflow:ellipsis; white-space:nowrap;"><a href="" style=" color:#c9c8cd; font-family:Arial,sans-serif; font-size:14px; font-style:normal; font-weight:normal; line-height:17px; text-decoration:none;" target="_blank">A post shared by MRF Motorsport Engineering (@mrf_engineering)</a> on <time style=" font-family:Arial,sans-serif; font-size:14px; line-height:17px;" datetime="2017-02-09T19:18:04+00:00">Feb 9, 2017 at 11:18am PST</time></p></div></blockquote> <script async defer src="//"></script>

    This is not confirmed but rumors are swirling regarding the S55 engine from the F80 M3 and F82 M4 going into the F87 M2 chassis. This would rectify BMW's mistake as the N55B30T0 motor is somewhat weak and struggles against the new B58 engine. If you look a the F87 M2 N55B30T0 power curve it just is all low end and the torque quickly drops off. How does that make sense for an M car designed for track use? The S55 isn't exactly BMW's best top end design but it offers a much broader curve with stronger pull toward redline. It's a better motor. So what is fueling these S55 into the M2 engine rumors? Spy photos from CAR showing cooling changes that look similar to the S55 cooling system. Not to mention Nurburgring testing from last year of an M2 said to have the S55 under the hood. It's possible only the CS model will get the S55 motor and the standard M2 will stick with the N55B30T0. If that is the case, the CS will be a much better buy. We'll know soon enough.

    Insane numbers here from an F10 M5 tuned by HC Performance. The S63TU engine has upgraded EFR turbochargers from Borg Warner and a built motor from Bimmer Performance Center in Raleigh, North Carolina. Other than the custom ECU flash dyno tune the car has upgraded clutches. The result? 846 horsepower and 772 lb-ft of torque at the wheels with DIN correction: There is more in it according to the tuner but apparently something in the transmission is holding is holding things back. The dyno run is claimed to be at 26 psi but there is no boost graph. Is 900+ whp about to become reality for the S63TU in 2017?

    Now this is an engine swap we can get behind. Actually, BimmerBoost covered this swap by Kinetechnik Motorsport way back in 2011. What makes it particularly impressive is not just the 5.0 liter S85 V10 under the hood but that they did the swap with factory BMW computers. BMW's own software reads the car as an E60 M5. Impressive, right? Well, not only is the work and electronic integration well done the car is simply incredible on the track. The engine sound is obviously glorious. It also has no trouble turning its rear tires into smoke at any time. The car now competes on a pro drift circuit and by the looks of things, is doing quite well.

    This is interesting as this is not the upcoming CS variant of the M2 which is expected to have a new motor. That model will actually be a true performance edition of the M2. What we have here seems to be a cash grab by BMW and an attempt to create a bit of hype likely in order to get rid of some M2's before their values tank. What is this Performance Edition M2? Nothing special. Dealer code ZL9 gets you manually adjustable sport seats, keyless entry without comfort access, automatic climate control, and the basic audio system. No frills here. They give it M Performance parts including black kidney grilles, black side grills, M illuminated door sills, LED door projectors, the M Performance Exhaust System with titanium tips, and the M Performance coilover suspension system. The M Driver's package raises the limiter to 168. This is an M2 with M Performance parts and no unnecessary options. There are only 150, all Alpine White, and the manual is the only transmission option. Should you opt for it at the $61,695 price? No. Wait to see what the CS has in store. BMW is hoping people bite on this as they know a better M2 is on the way for 2018.

    800+ horsepower to all four wheels is pretty much the norm now for M157's with upgraded turbochargers. These two AMG's both have turbo upgrades although from different sources. Let's look at the E63 AMG S first: 799.45 to the wheels but let's just be nice and round to 800. This output is achieved with AMS turbochargers, AMS airboxes, Weistec charge pipes, an AMS upgraded transmission, and a meth kit. Precision Tuning ties it all together. Now onto the CLS63 AMG S which has Forced Performance turbochargers. It is on the stock transmission so the 847 wheel horsepower tune (wish we had the full graph with the torque) will likely be dialed down. Still, impressive peak figures on the stock motor and transmission: Both cars are running methanol to hit these figures and that is important to note. It is also important to note that ~800 horsepower to the wheels is regularly hit with M157's these days. The platform is doing well.

    Going 8.5 in the 1/4 mile at over 160 miles per hour is already incredibly fast. When you point out that this twin turbo Lamborghini Huracan achieves this feat on the stock engine and gearbox it becomes all the more absurd. What makes this possible? A Syvecs standalone and a pair of Precision turbochargers. Gosha TurboTech from Russia put together the turbo hardware. The car dyno's over 1000 horsepower on a Mainline hub dyno and we assume this graph is at the wheels: Obviously the power shows in the slips: You have multiple 8.5X second runs with 1.3X 60 foots at over 160 miles per hour. What is there to say? The Huracan is an incredible platform with boost. Note: These runs were done at Yas Marina:

    This is kind of pathetic. How hard is it to launch an automatic DB11 exactly? What is so complicated here? The MotorTrend test driver can not seem to figure it out. He complains about the low end yet this is a 5.2 liter twin turbo V12 with 600 horsepower we're talking about. Low end torque is not the problem. Wheelspin is as the test driver struggles to put the power down off the launch. He complains that the power should be linear and flat but apparently is new to turbochargers and how they work. If that is the power delivery he expects he should look at the naturally aspirated V12 powered car the DB11 is now replacing. This testing takes place at California Speedway. They have a burnout box. Why isn't it being used? Secondly, if on the drag strip why not make the full use of it with some actual drag rubber to show how the DB11 can really accelerate? What is the point of going out to a strip for acceleration testing and making pathetic attempt after pathetic attempt? On one hand he complains about it bogging yet he also complains about wheelspin. Ok, load up the torque converter (use the hand brake if you need to) and do an aggressive launch on some proper rubber. Finally he gets a 0-60 time of 4.0 and a 1/4 mile sprint of 12.1 @ 124.7 miles per hour on a Vbox. They did not include the full data because apparently they prefer talking to showing the full test results. Expect better numbers from people who know how to launch on a dragstrip.

    Very nice gains here on a Lamborghini Aventador. The car is naturally aspirated with a 6.5 liter V12 providing 691 horsepower from the factory. Torque is at 509 lb-ft. This output is sent through all four wheels. Getting power out of a motor that is already over 100 horsepower per liter in naturally aspirated form is not easy. VF-Engineering is able to increase both torque and horsepower by 40 at the wheels respectively: Strong gains and as you can see gains throughout the curve. Peak horsepower hits roughly 600 at the wheels on a stingy Mustang dyno. All achieved on 91 octane pump fuel to boot. Not many people tune their Aventadors (this software is not exactly a volume seller) but for those who want more out of their Lamborghini VF-Engineering can provide very nice gains with their ECU tuning.

    AWE-Tuning is tackling the M177 motor of the W205 Mercedes-AMG C63 and S models. They have two exhaust options available with what they call a 'Switchpath' valved system as well as a track edition system which as you can see essentially ditches the mufflers. This is the spec sheet: Max power gains of 19 hp and 26 ft-lbs of torque at the crank Available as the valved SwitchPath™ Exhaust or the aggressive Track Edition Exhaust Easy options for cars with and without the Dynamic Performance Exhaust Engineered, designed, and handcrafted in-house at AWE Tuning Dual 3” diameter TIG-welded CNC mandrel-bent T-304 stainless steel Optional AWE Tuning Machined Exhaust Tips available in three finishes Featuring the unprecedented AWE Tuning Fitment Guarantee No Check Engine Light Guarantee AWE Tuning Lifetime Warranty (one year on exhaust tips) As this system does not include downpipes it is more about uncorking the exhaust note than power and torque gains. The AWE-Tuning dyno does show gains though: Now, obviously that Mustang dyno is highly corrected as the C63 S is not doing 508 horsepower to the wheels stock. On a Dynojet, output is roughly 467 horsepower to the wheels. This Mustang is reading quite high. Regardless, the delta is what is important. You see moderate torque gains through the curve with peak horsepower increasing by 12 at the wheels. What does it sound like? This: It has a nice growl to it. The track edition is a bit meaner though: The track edition is cheaper but for those who want the ability to make the car either louder or quieter at the push of a button will need to opt for the Switchpath system.

    There is a war of words already going on between Mercedes-AMG's Formula 1 drivers. It was kicked off by Lewis Hamilton's father who stated that being teammates with Lewis is potentially 'career ending' and that the teammate should make other plans for the future. Seriously, here's the statement: The dad is being supportive as a good dad should be but he is also saying Hamilton will end the career of newly signed Bottas as he will not be able to compete with his son. For his part, Valtteri Bottas had a pretty good response: Oh, and this: The season starts March 26th in Australia.

    Very cool project here from New German Performance. They did the grunt work in taking out the engine from this Lotus Exige and replacing it with a Volkswagen 2.0 TSI turbo motor. The swap is actually quite clean and very well done. The motor looks right at home. A Stage III turbo kit from APR was sourced and installed. The car is now at APR for final tuning. The final result should be something spectacular as the roughly 2100 pound car will have a lot more power and torque. If we go with a conservative 400 horsepower the power to weight ratio will be 5.25 pounds per horse. In other words, roughly that of a Gen V Viper with more power on tap should the owner turn up the boost.

    Well, the Demon is definitely shaping up as a car that will be at home on the 1/4 mile dragstrip. The most recent teaser shows the car launching hard and the sidewalls wrinkling. The higher stall converter will mean higher rpm launches. Additionally, the shorter 3.09 final drive ratio (up from 2.62) means more torque multiplication. The Demon is clearly all about getting off the line. Those 315mm Nitto NT05R drag radials sure are going to come in handy.

    This is some serious power out of the 2.0 TFSI I4 motor. Especially when you consider that the result is on 93 octane pump gas. This MKVII Volkswagen Golf GTI with the APR Stage III+ turbo upgrade kit makes 454 horsepower to the tire. That output comes with 427 lb-ft of torque at the wheels. This is a GTI that is going to surprise a lot of people especially on the highway: This car features the latest tuning revisions from APR which show some nice gains. It will be interesting to see what the latest revisions do on the 100+ octane race maps.

    Well, a hell of a lot quicker. Which it should be as the McLaren P1 GTR is a multi-million dollar track special with over 1000 horsepower. The P1 GTR takes everything that is great about the P1 and makes it even better specifically to shave time off laps. It's lighter, more powerful, and it is not street legal. The Mclaren 675LT is street legal however and also a fraction of the price. It also offers a fraction of the performance as despite the 675LT being a rocket the P1 GTR trounces it by four seconds (as it should): It does so on a fairly short and tight track as well. A difference of four seconds in that context is a lifetime. You know what they say, there is always a bigger fish.

    A dealer's Instagram post (since deleted) launched speculation across the Porsche community. Obviously the 981 Cayman GT4 model was well received and a Porsche for the purists. The GT4 only offered a manual transmission and had a 385 horsepower 3.8 liter naturally aspirated flat-6 powerplant. The only naturally aspirated Porsches produced today are the GT3 models. A new Cayman GT4 is likely on the way and if so that likely means it would have to borrow either the GT3 or GT3 RS engine as the old flat-6 from the Carrera S is no longer produced. Then again, the 991 GT3 and GT3 RS engines share many parts with the 991 Carrera S on which the 981 GT4 motor is based. The Cayman GT4 RS obviously will not be allowed to step on the toes of the GT3 or GT3 RS so expect power to be reigned in somehow. Rumors are output of 425 horsepower at the moment. Will the GT4 RS be manual only? Will it come at all? There is a lot to speculate on here. Let's hope this is a real leak and it's coming.

    McLaren is starting to share some technical specs for the 2018 720S (P14). The motor is a V8 with 4.0 liters of displacement. One likely can expect a variant of the award winning 3.8 liter M838T V8. So more displacement and more power to go with it. Not to mention, less weight. The car is going to be a rocket and McLaren says it will do 10.3 seconds in the 1/4 mile. Expect to see these cars in the 9's stock. Additionally, McLaren states acceleration from 0-124 mph (200 kph) takes only 7.8 seconds. To put this in perspective, the 488 GTB is claimed to do the same sprint in 8.3 seconds. A Porsche 918 Spyder takes 7.2 seconds. If one were to guess, this will be a 140+ trap car stock. The performance bar just keeps going up. SECOND-GENERATION McLAREN SUPER SERIES SET TO RAISE THE LIMITS OF SUPERCAR PERFORMANCE 15 Feb 2017 New 4.0-litre engine will power second-generation McLaren Super Series Twin-turbocharged V8 provides stunning performance: acceleration to 200km/h (124mph) takes 7.8 seconds and the standing quarter mile 10.3 seconds New exhaust system has been tuned to provide a soundtrack to match the extreme performance of the engine, with the further option of a sports exhaust Engineered beauty of new 4.0-litre engine showcased by engine bay illumination as part of the welcome sequence on vehicle unlocking The second-generation McLaren Super Series, which will make its public debut on March 7 at the 87th Geneva International Motor Show, is poised to raise previously accepted limits of supercar performance. Drivers will be able to enjoy acceleration from standstill to 200km/h (124mph) in just 7.8 seconds, accompanied by a soulful, clean and crisp exhaust note that is among the most emotive of any McLaren. “The new 4.0-litre M840T is an outstanding engine powering an exceptional supercar capable of covering a standing quarter mile in 10.3 seconds,” commented McLaren Super Series Vehicle Line Director, Haydn Baker. “Power, torque and throttle response are all significantly enhanced compared to the first-generation Super Series, yet with fuel efficiency and emissions also notably improved.” The ultra-low inertia, twin-scroll turbochargers fitted to the new M840T engine typify the engineering philosophy of advancement in every area, pursued throughout the development of McLaren’s new supercar. Spooling up more rapidly than previous designs, they deliver reduced turbo lag and quicker throttle response. The new 4.0-litre engine signals its performance credentials with an exhaust sound achieved through a sophisticated balance of harmonics and delivering a ‘crescendo’ characteristic, according to engine rpm and load. A sports exhaust is optional for those who want still more aural excitement. Owners will also be able to showcase the heart of their new car – in particular, the cast-aluminium air intake plenum with McLaren Speedmark logo on top of the new V8 engine – with engine bay illumination that operates on vehicle unlocking. More details of the second-generation McLaren Super Series, including engine and performance specifications, will be confirmed on March 7.

    Ferrari has not totally abandoned the naturally aspirated engine at least not in V12 form. They are still massaging their V12 architecture and this latest result makes for the most powerful naturally aspirated Ferrari V12 ever although it matches the output of the 6.3 liter unit in the LaFerrari hybrid. The specs of that motor are as follows: Ferrari LaFerrari - 9250 rpm 6.3 liter V12 Horsepower: 789 Torque: 520 lb-ft Bore x Stroke (mm): 94.0 x 75.2 Fuel Injection: Direct Aspiration: Natural Piston Speed FPM: 4564.304 The 812 Superfast matches the horsepower at 789 but torque is slightly higher at 530 lb-ft which can likely be attributed to the displacement advantage of the 6.5 liter motor. It does not rev quite as high as the LaFerrari 6.3 liter though with a redline of 'only' 8500 rpm. This output tops the special edition F12tdf but that car revs to 8900 rpm and has quite a bit of weight stripped out. Expect a hardcore variant of the 812 Superfast down the line as well. The dual clutch transmission carries over from the F12 and of course the layout is still front engined and rear wheel drive. What does it weigh? Ferrari claims 3362 pounds dry but Ferrari often lies. 35XX pounds with fluids would be incredible. Expect something in the 3700+ range if they even hit that. Weight distribution is said to be 47/53 front to rear which is excellent. The styling is sleeker and more natural of the F12 although clearly an evolution of that design. Quite simply, this is an awesome car and the world's most desirable GT.
