i just put on m/t drag radials,took about 50lbs off the car,and im going to the track tonight. my best is 13.18@ 108. ive got some bolt ons and a stock clutch. what tire psi and rpm should i launch at. i really want 12`s

 

well I did 12.9 @ 109, launching at 3800....unfortunately my clutch slipping gave me a 2.0 60'....but lower your tire pressure to like 15psi...and btw...what mods do you have?

 

ive got long tubes , gutted cats , flowmasters, granatelli maf, k+n drop in, predater performance tune(what ever that is). ive been gathering parts to install in dec. so far ive picked up a set of patriot ls6 heads, a cartek cam , 90/90 fast, and a stage 3 spec cltuch.

 

i ran 12.8 with the mods in my sig and i was running 17 psi in my fusions zri's and was launching at 2500 on a stock clutch i had one 1.85 60 but most were 2.0 and higher... still cant figure it out... good luck to ya...
