Automatic, oh and I did go through the water box all four times and did a quick burn out. I've been hearing not to go through the water box if you have street tires? I didn't think I was sleeping or spinning when it turned green but maybe I did for just a second, can't remember.

I always have it in S. I've found if you floor it with T/C on that's when wheel spin can be detected and the 'puter will compensate resulting in some hesitation till the tires grab. I try and ease into the pedal until I sense I've got good traction then I nail it. still working on it.

Ok, thanks GTO. I figured that by keeping TC ON and then flooring it, the car will want to spin and then the computer will cut the power for a second until there wont be any will spin. It makes sence that you need to feather it off the launch. Guess I'm going to have to test this out next time I'm at the track.

It's a great experience. Most folks at the track are helpful and can give great advice (usually...grain of salt and common sense). Avoid the waterbox (the treads bring water to the staging area) and avoid the main groove when you stage (starter might line you up). I get a moderate rev and engage the clutch no faster than I can roll the throttle up. Too fast - I lurch or jump. Too slow - I'm slipping the clutch or spinning tires.

To me that first to second shift is the most important. Third just needs to be quick as hell and 5500 maybe a little higher seems about right.

Let me know how it goes. If you're at the Camaro5fest you'll have a great chance to try it out! Only 36 days.

haha whoops. On it! Yeah... 60' is killing me.. Any suggestions? I try flashing it, with and without TC, I once loaded the trans at 2k rpms but didn't really do much better. Although I got 9 runs in, and my engine and oil was getting pretty warm. First three runs and my last one were only the ones worth looking at..

GTO ran 101 mph in the 1/4 mile so his car is moving faster down the track. If he had been able to pull a faster 60' time (say 2.0), he would have run
13.7 or 13.8 in the 1/4 mile.

Also, take note of the DA (-1300 ft) of his run. That's is a very low DA and your car will make more HP and run faster.

That 101 is simply amazing! I've got a faster trap at the 1/8th but he's got a faster trap at the 1/4... Still trying to figure that one out! LOL

Skill no doubt!! I just looked over the time slips from that day. Out of 8 passes, only one was under 100 mph @ 99.27, the best was 101.55.

Best 1/8th was 79.12.

Ahhh, didn't look at his DA, guess that has A LOT to do with it. Considering my best run was at 1537
