    I just wonder whether these rather extreme torque gains are not a problem for the double clutch transmission, at least for longer than just a few thousand miles.

    Not much really needs to be said here. Obviously, this network likes the 2015 Ford Shelby Mustang GT350R. A lot. We like like it. With recent reports about it being able to hang with the Porsche 911 GT3 combined with these good looks we have no problem admitting the infatuation. It's just a hell of car.

    This is running renntechs upgraded turbos it says so in the video ! Still pretty damn impressive with 620whp on a superflow dyno and the car is hauling ass in that video interested in what the 1/4mile times and trap speeds are

    Very impressive Stage 2 M178 tuning numbers here from Renntech. As you may recall, Renntech started work on the M178 motor early this year. They showed a baseline of 531 crank horsepower and 472 wheel horsepower. They have the AMG GT S with their turbo upgrade and downpipes up to 682 crank horsepower or 625 at the wheels on their dyno now. Those are some major gains. Torque alone is up by 242 lb-ft over stock. What is also nice to see is how flat the M178 torque curve is once the motor spools and how the torque curve does not really start to drop hard until past 6500 rpm. The M178 in general is definitely breathing better up top than the M177 in the C63 especially this example. Renntech previously shared an acceleration video of their intermediate tuned AMG GT S running up to 195 miles per hour and this time they take it to 199 miles per hour with the Stage 2 setup. The car accelerates hard with the Stage 2 package and the gearshifts look to be about instant. They get to 198 miles per hour in no time. It's incredible how easily the car gets there and with no drama whatsoever. This car is fast. It will be interesting to see how much further Renntech takes it on the turbo upgrade with race gas but for now they obviously are not pushing the transmission beyond its limits.

    Ford held a press day for the upcoming GT350 and GT350R Mustang models at the 2.0 mile long Grattan Raceway in Michigan. Ford provided some key information on the GT350 and GT350R including that their curb weights are 3760 pounds and 3650 pounds respectively. Not light but not super heavy either. Oh, and how about the fact the GT350R beats the 911 GT3 by 1/10 of a second at this racetrack? That is the Ford press claim. Things may change on different days on different tracks but what it shows is that on the racetrack it is a driver's race between the GT350R and the 911 GT3. That is incredible considering the GT350R is less than half the price.

    This is something we are going to see more of as the new M3 and M4 battle with the 335i and 135i models equipped with the N54 (with N55's more and more getting into the mix as well). This goes down about as one would expect with the F80 M3 pulling up top. The M3 has the advantage of the DCT transmission. The Eurocharged ECU flash tune with downpipes as this M3 has boosts things considerably. Basically, a bolt on F80 M3 should make a bit more power than a bolt on E9X 335i N54 but the N54 has some additional tricks up its sleeve that this particular example is not running including inlets and E85. This particular N54 is running meth injection though and the F80 M3 S55 is not which is a factor although it is on race gas. Ultimately, these are both 3.0 liter twin turbo direct injected BMW inline-6 motors and which is faster comes down to the amount of mods and really money spent. The M3 will ultimately have the advantages of the DCT transmission and the higher redline. It also is the more complete package to begin with. It's a bit of a shame these are chase view runs on the video (it should be a crime really) but it goes to show how quick a tune and downpipes M3/M4 is and how it stacks up to a bolt on N54.

    In the August 2015 issue of AutoBild there is a small tidbit on the R8 model expected to slot in below the V10 model. Thanks to our German members we can provide you with the details. You will notice on the far right of the article page it is mentioned that a 450 horsepower 2.9 liter V6 will slot in below the V10. This makes sense for several reasons. First of all, Audi themselves confirmed the V8 is gone and set to be replaced with a smaller turbo motor in the R8. Many outlets reported that the 2.5 TFSI inline-5 is the motor that would be used. The next generation RS4 is confirmed to use a turbo V6 powerplant. The logical conclusion based on Audi precedent is that the RS4 and entry level R8 will share the same motor as they did with the 4.2 FSI V8. This means a turbo V6 and AutoBild confirms this. They do not cite a direct source for their report but keep in mind in this same AutoBild article they have an interview with Audi Quattro boss Heinz Hollerweger. It is likely that he wanted this info not attributed directly to him at this stage so he is likely the unnamed source. All signs currently point to the RS4 and R8 sharing powerplants once again.

    The all wheel drive Tesla Model S P85D is very quick for a sedan especially below 100 miles per hour where its 864 lb-ft of torque at the wheels makes for a formidable stoplight car. The McLaren 650S is also very formidable with a much stronger top end punch. What does that mean? It means this race goes down like most P85D races where the Tesla sedan has a slight lead and then the top end horsepower of the internal combustion car it is racing takes over. This race is far closer off the line than the others though as the 650S gets a slight advantage on the launch. The Tesla hangs in for a bit even pulling slightly down low but it's quickly over as the 650S pulls away effortlessly. It is not even close as the 650S puts bus lengths on the P85D. Considering the 650S Spider is quicker than an Aventador there is no surprise in the outcome except that the 650S launches very well and even off the line the Tesla can't open up any real advantage unless it gets the jump as it did in the second race. Note that this is not the 'Ludicrous Mode' upgrade coming from Tesla but all the new mode can do is delay the inevitable as you see here.

    Cobb's Porsche 991 Turbo tuning development continues and they are moving rapidly. Below are results for Cobb Stage I and Stage II OTS (off the shelf) tuning. These numbers are results anyone can expect with the OTS tunes and of course they can be further customized if one wishes. The torque gains massive with just the Stage I OTS tune on pump gas. They were able to pick up an additional 107 lb-ft of torque at the wheels. Stage II on pump gas takes this to 652 lb-ft of torque at the wheels for a gain of 120 lb-ft. The biggest horsepower gains come on race gas but that raises the question of diminishing returns due to cooling issues. PorscheBoost of course already explored 991 Turbo and Turbo S heat soak issues and Cobb is well aware of cooling limitations especially when tuning. Cobb is working on intercooler upgrades to overcome any limitations and push things forward. Impressive work thus far. Our Porsche Experts have been hard at work making sure we’re all set for the Porsche 991 Turbo Accessport release which is getting closer by the day! The most fun part of that process is strapping the cars down to the dyno and seeing just how much power they make after a bit of tuning. We were extremely lucky to be able to work with Porsche of Colorado Springs for the Pikes Peak International Hill Climb. That experience enabled us to learn a TON about these cars and how they react to different tuning strategies, aftermarket bolt-on parts, or differences in fuel quality. Below, we’ll take a look at some of the power gains we’ve seen. First, on an otherwise stock car followed by gains associated with an upgraded exhaust and appropriate tuning. As a note, the data in the graphs was recorded on two separate days however the delta from the baseline pulls remains accurate. Seen here is our initial Stock Baseline pull on 91 octane fuel along with a Stage 1 OTS map using 93 octane fuel. A Stage 1 map would be used on an otherwise completely stock vehicle. Power under the curve is significantly increased throughout the low and mid range. Maximum gains of around 60whp are seen between 3000-4000 RPM. Most impressive is the increase in low-end torque, with gains of over 100 ft/lbs! Next up, Stage 2. A Stage 2 map is calibrated to be used on a car with upgraded exhaust. As is evident with the power gains, the motor is able to flow a significantly greater amount of air with the freer flowing exhaust. With gains of 120 ft/lbs down low and nearly 100 hp at peak, the cars become a whole new animal. We are able to be a touch more aggressive utilizing 100 octane fuel, this will be a great option for customers interested in tracking their car where detonation resistance is key. Stay tuned as we continue development on this platform. At this point, the cars will really need an improved cooling system to make any additional power. We’re already in contact with top intercooler providers in the industry with intentions of overcoming the next bottleneck in power.
