Okay, well last night was my first trip to the track. I posted a thread about where to launch with a stock GT on street tires but I didn't get an answer until it was too late. So, I decided to wing it.
My first run.....
I put my psi down to 30 ( I typically run 45 ) and didn't do much of a burn out. Well, when I staged and launched I spun like crazy and when I shifted to 2nd it bogged down on me. Here's the #'s...
R/T - .425
60' - 2.632
330 - 6.959
1/8 - 10.298
MPH - 73.68
1000 - 13.154
1/4 - 15.546
MPH - 92.45
My second run.....
Left the tire psi the same and did a wicked good burn out. To all you nay sayers, burning out with my street tires made a HELL of a difference! Here's the #'s...
R/T - .381
60' - 2.120
330 - 6.021
1/8 - 9.528
MPH - 76.00
1000 - 12.045
1/4 - 14.390
MPH - 96.09
My third run.....
Nothing changed. Here's the #'s...
R/T - .546
60' - 2.041
330 - 5.931
1/8 - 9.175
MPH - 75.75
1000 - 11.966
1/4 - 14.317
MPH - 95.92

also, he might have been at a better elevation, better conditions, humidity, temperature, thousands of factors, so its not that unforseeable. 275mm is ALOT of tire, regardless whether its ****ty or not, and its not a lo pro (40) meaning he still has some sidewall to move around. 2.0s are def possible.
