    This is not surprising as BimmerBoost last year reported that all wheel drive coming to the M5 is an inevitability. What is surprising is just how quickly things are moving in that direction as BMW is already testing an xDrive all wheel drive equipped F10 M5. This all wheel drive M5 was spotted in Sweden which during the winter as you can see is a pretty good place to test traction. Apparently the front wheels did a slight burnout prompting a photographer to go underneath and see the front driveshaft confirming all wheel drive. All wheel drive is coming because these cars have become so heavy and utilize so much low end torque. The M5 is more about muscle than ever in its history and really is becoming a dragster. Well, the traditional rear wheel drive layout is making traction a problem and considering most owners just want to go fast in a straight line instead of hustle around the track (the old AMG recipe) traction off the line is the point of emphasis. Especially considering that the next generation M5 will likely get a tweaked F10 M5 S63TU 4.4 liter twin turbo V8 with horsepower bumped to the ~630 range. It is unlikely that BMW will release an all wheel drive F10 M5 (although they clearly could) and more likely that this is a test mule for the next generation M5 powertrain which will be very similar to the F10 M5 powertrain. Expect more weight on the nose, more understeer, and for traditional BMW handling characteristics and balance to take a back seat toward straightline performance. It was nice knowing you M.

    Very nice numbers here from a GIAC tuned Porsche 991 Turbo S. The vehicle is running the GIAC Stage II race gas tune which is an ECU flashed tune. In addition to the tune plus race gas this 991 Turbo S has the Tubi catless race exhaust and the IPD intake plenum. The owner used launch control on the runs and as you can see the car was incredibly consistent. 132 mile per hour traps each time and the 60 foot ranges by less than 1/100 of a second. That is some serious consistency not to mention the launch control system is highly efficient hitting 1.4X. The tires used are Dunlop Sport Maxx Race which is a street tire but basically an R compound. So what else is needed for this car to be the first US 9 second 991 Turbo? Good question. It is somewhat perplexing why US 991 Turbos can not break out of the 10's yet we are seeing many record breaking results on the same dragstrip in the Middle East.

    What is the best upgraded turbo and fuel option for FBO on 93 octane? I do not want to run meth and the car is a daily driver. I see lots of dynos and claims for ethanol whp records but the nearest E85 station is 45 mins away from me. I do have quick access to 100+ octane though. Am i really going to gain much by going to stage 2 over stage 1 twins on 93?

    Hey guys, I finally got my car returned to stock turbos from the single and trying to return the cobb to stock map. Upon first attempt it lost communication with ecu and went into recovery mode. I ran recovery and it said it was successful, then I tried to flash stage 0 again and when I click on change map it can't identify ecu. Any ideas?

    The M133 engine is finally getting more flash options on the market. Up until now Renntech was the only tuner offering a real flash tune. The vast majority of the other M133 tuning options were piggyback tunes which of course have their plusses and minuses depending on your tuning goals. Flash tunes tends to offer more control over various parameters but it is ultimately personal preference. What is important is that M133 tuning is taking strides forward which is good for everyone. Eurocharged recorded a baseline wheel horsepower figure of 330. After the tune this rises to 380 for a very impressive gain of 50 wheel horsepower. The baseline torque figure is 334 lb-ft at the wheels. After the tune the peak torque rises to 430 lb-ft at the wheels for a gain of 96 lb-ft. The M133 definitely offers incredibly torque stock and tuned. The turbo does look like it runs out of steam past 5500 rpm though as if the torque did not drop off so sharply the M133 would easily make over 400 wheel horsepower. The Eurocharged tune retails for a very reasonable $999. The ECU must be sent in to either the Houston or Toronto location. OBD-II flashing is not yet possible but that will come with time. This is just the beginning but the future of M133 tuning certainly is bright.

    The Acura NSX debut at the Detroit Auto Show was somewhat overshadowed by Ford taking over the entire show with a barrage of performance cars. Well, that is what Acura gets for teasing the new NSX forever and finally getting burned by losing the spotlight. That is how it goes but an interesting tidbit that came out of the show that everyone glossed over was that the chief engineer for the NSX Ted Klaus said to expect a Type R variant. The previous NSX of course was offered in Type R guise just not in the USA. So what would a Type R variant mean? Probably 30 or so more horsepower than the standard 550 the NSX offers along with some weight stripped out. An all wheel drive twin turbo V6 NSX with 580 horsepower and a 9-speed DCT transmission moving a more hardcore and lighter version? Sounds good to us. Source

    It is still very early in the C7 Z06 LT4 tuning game but Lingenfelter is making some big progress. There are critics that feel the 1.7 liter Eaton unit Chevy chose for the C7 Z06 is simply too small of a blower. Chevy defends their choice in that the 1.7 liter unit is lighter producing less heat and that the smaller rotors generate low end torque quickly. They have a point but for those who are power junkies a larger blower is no doubt on the menu. Lingenfelter has swapped out the TVS 1700 for a TVS 2300 courtesy of an adapted Edelbrock E-Force Corvette system. The 2.3 liter blower pays dividends as at 13 psi of boost it provides roughly a 100 wheel bump (68X WHP range). The TVS 2300 unit can obviously be cranked up past 13 psi and on race gas with high boost 800+ wheel horsepower is within reason. The TVS 1700 will see diminishing returns much more quickly than the TVS 2300 once boost is cranked up. Also, this should not be too difficult of a swap considering these are both Eaton units. The hardware is clearly already possible as Lingenfelter shows and tuning is the main hurdle. A 2.3 liter blower still is not exactly huge and it would be awesome to see a huge whipple twin screw on the LT4 although then the blower would stick out through the hood. A small price to pay for such awesomeness though.

    Fishayyy started a thread Slipping clutch? in N54
    Well it seems my clutch is starting to vibrate when it engages in 1st gear unless I really baby the engagement and after I drive hard or just drive for a long time I can smell a burning smell coming from somewhere. So considering all of that I'm assuming my clutch is starting to go out, should I get a new one? I've been thinking about getting a Motiv or a Spec Twin Disc clutch with a SMFW, but I really haven't looked too much into aftermarket clutches yet.

    I am attempting to do some research on how inlet air temperatures are being effected by my ESS VT-650 kit and how efficient the intercooler design is. I am running the BMW Data logger program while conducting a few maximum rpm pulls on the highway. This was in no way a controlled test as I am just starting this and wanted to get a basic idea of what is going on under the hood. I am also having trouble with the BMW data logger continuously dropping offline. Ambient temperature was 60 degrees. While driving at 70mph and engine completely warmed up IATs began at 83-85 degrees. After only two 3rd to the top of 4th gear pulls IATs yielded a 148 degree peak. It took about 5 minutes for IATs to come down to 90 degrees where it stabilized. After the IATs stabilized I pulled over and checked under the hood temperatures. Using an infrared thermometer the large air filter measured 100 degrees. The small air filter measured 130 degrees. I am looking into putting a temperature sensor at the filter to get a more accurate reading of how hot the air is that is actually being sucked in. Even though this was a very rough test, the results do not look good to me. IATs stabilizing 30 degrees above ambient at highway speeds does not seem efficient. Also, seeing 90 degrees above ambient after a few hard pulls on only 7psi does not seem good either. Supercharger outlet temperature = ambient + (10 * psi) right? I welcome any comments. Any boost experts out there?
