GT700 at Altitude
#61
Just got back from the track. Temp was about 80F and Bandimere is 6000' absl.
Car ran really well tonight:
60' 1.825
330 5.089
1/8 7.612
MPH 99.11
1000 9.743
1/4 11.529
MPH 127.21
NHRA altitude corrected is 10.84@134.37
Unfortunately the spline (I think that's what it's called) broke by the wheel on the half shaft on my third ran. This happened three weeks ago so it's twice in three weeks! The half shafts are upgraded by Evoms but the stock spline is still used. I was trying to watch my launches tonight and stayed at about 3400-3500 rpms. Any one else having this problem?
Todd from Evoms will be here in Denver tomorrow to tue the GT2 and Cayenne for altitude. I'd really like to see low 11's by the end of the season.

Chance,
The car is at the dealership. Todd was able to track down the part and it will be at the dealership before 10:30 a.m. This way we can tune in the afternoon.
This time the spline actually flew out of the wheel. I put the peice on the driver side floor. Wait until you see it!
Talk to you tomorrow and thanks for you help,
John

I also found out that I've been short shifting. I didn't realize that the rev limiter was raised to 7200 rpms until Todd told me. I've been shifting at 6500 rpms which is the stock red line.
Hopefully a good launch, once the spline issue is fixed, mixed with reving the car to its limit will get me low 11's, maybe a high 10 second run. I've been using 5th gear due to the short shifting which I no longer need to do.
The Cayenne made a huge gain with the canges that Todd made. It picked up over 70 whp making about the same power as the GT2 to the wheels. When you consider the drive train loss on this vehicle these numbers are impressive.
It was a fun day getting these dialed in and Todd's a great guy.
