1989 iroc-z

Hi guys finally took my new car to the track the other night and basically i'm curious at how i compare to others with close to the same setups.

my car is a factory 305 tpi with t5 5spd, im running a set of elebrock headers and custom 3in borla exhaust. I just swapped all fluids to full synthetics, the rearend is either a 3.23 or 3.08 ratio, i beleive 3.23 but, i only did the spin check so may be either, it is posi and hooks both tires very well. Also has an aftermarket alminum driveshaft airfoil and k&n filters, 350 injectors and afpr.

anyways i couldn't get it to launch all night so the times were terrible but, my trap speeds were consistent and fairly high i beleive for what it is, i trapped at 92 mph all night all my shifts were fast and precise but, my best 60 footer was 2.34 (i know terrible should a cut 2.0 easy).

basically my question is where would my traps speeds be if i could get my 60 footer down to a 1.9 or 2.0. I trapped a best of 15.0 flat. What would my tme be if i could get it down to a 2.0 or a little lower (very minimal track experience here) basically curious how mine stacks up compares to other because, it seems faster than most imo.
