    GIAC Tuned 997.2 Turbo S takes on all comers in a 1/3 mile roll on including a VT3 M3, GTR, E63 AMG, F10 M5, MP4-12C, Supra, etc.

    This is a compilation video showing multiple runs at a recent 1/3 mile roll on event. Due to the event being 1/3 mile the shift speed of dual clutch cars definitely favor them in such a scenario. Shift speed is the advantage of the transmission and it shows. This 997.2 Turbo is equipped with a GIAC tune and an aftermarket intake plenum. Wheel horsepower is approximately 530 horsepower on a Mustang dyno. This GIAC tune has powered 997.2 Turbos into the 9's in the 1/4 mile.

    There are several runs here so let's analyze them one by one.

    Run 1 - ESS VT3 supercharged M3 ~690 whp

    The Porsche gets a bit of a jump and due to its all wheel drive traction advantage takes an early lead. It holds off the VT3 through the run although it starts inching back. Regardless, this M3 despite being a built motor car only managed 135 in the 1/4 mile which a GIAC tuned 997.2 Turbo S is also capable of. The top end advantage goes to the M3 but the runs are not long enough for it to show.

    Run 2 - Rematch with the VT3 M3

    Closer start this time between the two cars and the 911 turbo takes just under a car length lead. The VT3 starts to pull up top again able to edge enough to take the win this time around. This is pretty much exactly how it should go down. The longer the race the more it favors the M3 with the shorter the race favoring the 911 Turbo.

    Run 3 - Bolt on tuned GTR with ~600 whp

    The 911 turbo again gets a jump. Seems to be a bit of a pattern. It opens up a lead that the GTR can not close by the end of the run where it is inching back in. It definitely has more power but loses due to the start.

    Run 4- MP4-12C Spyder

    The Spyder is a little heavier than the coupe but it really is a marginal difference. Jump from the 911 Turbo yet again and the MP4-12C does not not have enough top end to close the gap.

    Run 5 - 996 Turbo MT with bolt ons and GIAC tune ~500 whp

    No contest. Eaten alive.

    Run 6 - 6MT 997.1 Turbo with ~600 whp

    Another jump but it does not matter. PDK wins this race easily.

    Run 7 - 997.1 Switzer built with 6MT and 800+ whp. Fastest car of the event.

    997.1 does not allow the 997.2 to jump on it. Simply too big of a power disparity here, game over.

    Run 8 - Gintani Stage II supercharged DCT M3

    M3 just looks like it lets off.

    Run 9 - Renntech tuned M157 E63 644 whp

    Pretty good start on this one but PDK wins the race despite the power disparity. The E63's weight does it no favors. A longer run would likely have the E63 coming back up top but it is what it is.

    Run 10 - 458 Italia stock with passenger

    It just gets flat out pulled, no contest.

    Run 11 - SRT8 300 with 850 whp

    Horsepower just manages to win this one up top but this goes to show how down low a dual clutch can minimize a large HP advantage significantly.

    Run 12 - Supra with 1002 whp

    Takes a second for the Supra to get going but once it does it just pulls away up top. Win for big HP.

    Run 13 - BMS Tuning F10 M5 ~640 whp

    Slight early start for the 911 Turbo. The M5's DCT pays dividends though and it stays with the Turbo and begins to inch up on the top end. Race is over before the M5 can pull past. Strong showing for the F10.

    Run 14 - 997.1 Turbo with full bolt ons, upgraded 68mm turbos, and meth injection ~650 all wheel horsepower

    A jump for the 997.2 but the horsepower of the 997.1 Turbo takes over fairly quickly. Too big of a power disparity between the two.

    Run 15 - 880whp Supra

    Lag, lag, lag, spool, win.


    Definitely a nice compilation here showing various outcomes and scenarios. What one should take away is that dual clutch transmissions in shorter distance roll ons where more shifting takes place are dominant. Additionally, such conditions favor a 997.2 Turbo as the lower rolling speed benefits all wheel drive traction. Overall, several good runs showing it is not always the most horsepower that wins and that it takes a large HP difference to overcome a starting deficit in a short roll on.

    I love seeing how much can be done with so "little" hp now. What is this 640 whp M5 though? What the hell is going on there?

    Might be because it says "BMW Tuning" up top instead of BMS Tuning Click here to enlarge

    I never read the site. I just lick on "reply" as soon as I find the word on a page and then mash my head on the keyboard until words appear.

    It doesn't, it says BMS.

    I think that's the preferred method for most users. It explains some of the posts I read.

    Great footage and great runs, wish I could've made it out there. Sticky in the video it says the VT3 M3 is "only running 10 psi at WSIR altitude," how much does it usually run?

    Who knows what the truth is but probably closer to 14.

    Just wanted to add something that's important to me, this article displays on BenzBoost, Porscheboost, GermanBoost, and BimmerBoost at the same time. Sounds simple but it really isn't and it makes a big difference as now my network expansion is completely possible with individual and shared front pages. It's quite awesome honestly.

    If you don't mind me asking, how much will your car be running? I understand if you don't want to answer on a public forum.

    I have no problem answering. The standard boost will be ~18 psi but my boost is different as I have custom headers specifically for an SC application which drop boost pressure and also a different compressor. The VT3 supercharger is the same as the VT2 and simply can't provide enough air or even reach those levels of boost.

    My high boost setup will be somewhere in the 20's I don't know how far. I'd like to spin the YSI to its max. The difference between the two will be several hundred wheel horsepower, no contest.

    This video and write up is the single BEST detailed comparison performance video I have seen.... outside of the PDK 997.2 beating the McLaren. I have seen a few other videos (such as Chris Harris's) where the MP12-4C destroys the Porsche above 100 mph

    Thanks for posting though... this is great and I suspect my 997.1 even tuned (its a 6MT) will need a 160-200 hp gain over a 997.2 Turbo S to get close.... food for thought

    How would a car like Terry's 135i do or an 800 whp E46 vs the 997.2 Turbo S

    Only down low. The higher the speed and the longer you are in gear the less important the PDK becomes. That said running from down low after a shift from 2-3 then 3-4 you will be going WTF.

    Terry's 135i would lose and the E46 would run into the problems the higher HP cars had. This is too short of a run at too low a speed. I wouldn't bother with 1/3 mile.

    Run 13 - BMW Tuning F10 M5 ~640 whp

    That blew me away... that the very heavy assed M5 kept up .......... it really is quite a beast and with further tuning by the aftermarket crowd is going to produce some startling results IMHO

    Pretty good start on this one but PDK wins(?) the race despite the power disparity. The E63's weight does it no favors. A longer run would likely have the E63 coming back up top but it is what it is. ???
