The one thing I did that really helped me was taking my tire pressure down to about 14psi. It's amazing how high the psi goes after a burnout and run down the track. I was finding my tires at almost 22psi after a run.

Basically what I did was start at 20psi and work my way down. You certainly don't have to take them that low, but that's where they hooked best for me. I made several runs the same night and 14psi netted me the best 60ft. Hopefully others will chime in and give you some other tips on where to start. I can't say my methods are all correct, they just work for me.

If you look in my signature, click on the "first 1/4 mile with 427". That was my best run at 11.52 @ 117mph with a 1.58 60ft. That was the run I dropped to 14psi. I don't have that motor anymore but I should be running about the same times.

ya for sure, no point in buying them if you dont heat them up right? im going this friday so it should be interesting, any guesses? ran a PB of 8.02@89.6 with a 1.9 60', never have hit a 60' that low, usually 2.0Xs, and 8.1Xs..

Hmm, is guess youll run 7.8x best and 7.9x all day. U should be able to pull off a 1.7 60ft. with brand new MT E/T radials, i got a 1.7 60ft with a shitty *** burnout. Given your times though, with a decent burn out your gonna dead hook!

1.9x's are decent for a street tire--Im guessing you werent spinning that much on that launch. With your level of mods I dont see you getting much lower than 1.8x's. If you are still running the stock convertor you are limited to how hard it will hit off the line with an A4.
