Default To N20 or not to N20?

Well i dont know if i wanna do it or not, just got a rebuilt engine and new tranny and i really wanna get my 1/4 mile times down. Theres that ZEX dry system for bout $500. Questions, #1 Approximately how much lower would a 75 shot make my 1/4? #2 is it safe with my engine? Any info regarding this would be appreciated?

Change your Hypertech to a Jet, and p&p your manifolds first. Then see where you are.

My car Gtech'ed at 60 with a 14.7, which I feel is a bit optomistic.

At Woodburn last friday, I pulled a 15.5 in full street trim, over 1/2 a tank of gas, and with track temps over 100 with no ice for the SC. I think a 14.9 in ideal conditions is achievable.

The only physical difference that might make a slight difference between our cars is that you don't have the full-roller valvetrain on your 92, and that'* not much of a difference.
