Markski, I am kicking aorund the idea of running both AWD and RWD at the dyno. The dyno tech is a member here and suggested I pop off the driveshaft while at the facility. It would be interesting to see what the difference is between AWD and RWD on the same car, same day, same dyno. 18.5 and 12.5... where do these numbers come from and how do they know this? Has Porsche published any info concerning driveline loss? Thanks, Kevin

I will try to make it happen. I will talk with the dyno tech, a fellow 6speeder and a 996TT owner,and see how his schedule is for that morning. I am also very interested. Kevin

I think scott's power guestimates are pretty close. I think it takes about 480-500 crank hp to trap about 120 or better in our cars. The launch and 60 ft times are not that great. The mph on the big end is not too bad. I am curious about KPG's dyno as I like the package he has and have considered it before. Very flexible and safe. I do think dynos can read all over the place but one thing is sure, a stock gt2 has been known to run 11.8 or 11.9 in the quarter. If you had one with 440 plus to the ground it should be just a bit better than this. No one is bashing your car or power just trying to state what most others are seeing. I do believe porsche underrates their cars on hp. Either way good luck with your car and if it is stock then you will crap your pants when it is hitting 1.2 bar and has another 50-60 hp. Enjoy!

Kevin, that would most definitely be very interesting. I'd love to find out the results.

If I could make one recommendation, and only if you guys have the time of course; 3 runs each, 3 in AWD and 3 in RWD, for a total of 6 runs...would allow us to get a more accurate average for both the RWD and AWD runs to find out the delta between the two.

Scott, I wiil try to make arrangements for the AWD/RWD. 3 runs each should not be a prob. Kevin
