it is a lot of pressure but talking to other cars on ls1tech (only good racing ls1 site) the guys are running them 18-22 psi. this is my first time out with those tires so ofcourse i started up high and was testing my way down. i dropped 1-2 psi on the second pass and went down 0.004 seconds on the 60'

lol

i think that 10-15 psi will cup the radial tire. but i am still learning this. i am launching at only 2500 rpms and the car isnt pushing forward yet.

there were 3 firebirds (two TAs like mine and one formula) in the "fast" lane (i call it the pro lanes). in fact i ran the formula once and right behind me was that navy blue car. btw, he runs n/t and i always show my times.
