lt1 1/8th mile with bolt ons

**96lt1z28** · 06-14-2006, 05:24 PM

I have a 96 z28 that ran a 9.21 at the 1/8th mile track. It had exhaust with a cai. I just now had the computer tuned,underdrive pulleys, tb bypass, maf ported and descreened, headers, y pipe, no cats, egr,air pump, 3" cutout with one chamber and borla tips, 160 thermostat, and new ngk tr55s with 8.0 plug wires. What should it run now?

Only way to know for sure is to go run it.

How many miles do you have on your lt1...i ran a 9.3 1/8 and toped out at a 14.410 on 1/4 at 97mph. mines a 1997 firebird formula A4 with the stock 2.73's....it has 125k on it. I have slp loudmouth exhaust, moroso cai and a hypertech power programmer....so something is wrong with my car if it couldnt beat your 1.8 time..i might need a tune up? What do yall think

I have a 96 T/A hard top and as far as I know it is stock. it ran 8:30's before I changed the muffler from stock to a Flow master. take in that I run Mickey Drag Radials. But on Street Tires it is runs 8:70's with no mods. What may be the differents in my car and the ones running in the 9's. Non ram air, Auto, egr and air pump factory exhaust except muffler.
