Default How fast? with new mods

I want to know how fast will I go before i go to the track this weekend and not be dissapointed. My car is a 98 Z28 which i ran last month and it ran 8.7 81mph at the 1/8 mile, since then I added pacesetter race headers, and a ls6 intake and a better ported throttle body and a good tune, and was wondering what should i run now, I'm realling hoping 8.3 or better.

depends on a lot of things: weight of the car, gears, track prep(go to redline or kennedale), tires, etc. looking at your mph is your car an auto? i would think a realistic low 8.50 will be a good estimate. my full weight car A4 car with gears, bolt ons, working suspension, MT et radials, and LS1 edit tune went 8.31 @ 87 mph on a decent track. good luck.
