Just got a phone call from Tym a few minutes ago. He is finalizing the race gas tune (R850) on my 997 GT2. I wanted to optimize my car for regular pump gas (93 octane) since i will be running it on pump gas most of the time. However, i also wanted the option of running race gas for those few occassions where the extra ponies were needed. Since the P800 (P = pump) has been installed, i have logged over 3000 miles on the car. So far, the car has performed flawlessly. On the P800 tune, the car makes 703 rwhp on a dyno jet. Tym has just finished the race gas tune and has let me know the car made 783 rwhp on C16 race gas at 26 psi of boost. With a conservative drivetrain loss of 10%, the GT2 is making 870 HP at the crank. I will be posting the dyno sheet as soon as i get it from Tym. Hopefully, I will be able to post 60 - 130 times soon. The GT2 went 6.06 s on 93 octane. So we are definitely hoping to get into the 5's. This entire package is a bolt on package and no internal modifications are required. Stay tuned!

 

Jeebus!!!

EDIT: We need video ASAP Pleeez

 

Crazy crazy crazy.......all Euro tuned cars need rods over 830NM or they bend, yours would bend if you ever managed to give it some "Euro use", example below:
Left scale in mph not kph BTW

 

maybe Euro tuners use a different tuning strategy. i don't know. we have many P800 cars out on the road (93 octane pump gas running 700 rwhp) running safely. my sledgehammer is also running with no problem and it is making 850 rwhp on stock internals.

 

imo, the main difference is ; in Europe, people always can do top speeds in autobahns. and whenever we roll, the race starts at 50 km/h and doesn't end before 300 km/h. American's usually run 60-130 mph runs and that's it.

 

tym went out to log the car. the first 60 - 130 was a 5.7s with one shift. unfortunately, 2nd gear just blows the tires away so it is difficult to do a 2 shift run. this was also with 2 people in the car.

 

very good. You should see somewhere 5,3 - 5,4 with one person, 1/4 tank of gas and on a cold weather.

 

Amazing and congrats DK. I can't wait to check out the car in person sometime.

Tym never ceases to amaze me.

Amazing! I really cant wait to see what a 997 Turbo with R850 can 60-130 with the advantage of all wheel drive?!? I think a low 5 is in the cards. Tym/DK again great work gents and let me know when I can pick mine up

 

Toby, I think your data is not correct. Considering the margin of safety that most tuners give (especially Ruf, who offers warranties on their engine kits), the stock rods on the GT2/TT can probably take a beating higher than what you are suggesting. Ruf 600 (850NM)...or Evotech 600 (840NM)...or TechArt (880NM)...all are reputable German tuners offering torque beyond your stated limit of 830NM...they would never off a kit without some margin of safety. My guess is that the rods for both engines can take a beating beyond your numbers safetly.
