It's a 383 now but..........

 

don't know my hp but i run a 14.3 with slp 1 3/4 headers flowmaster cat back random technology cats and just little stuff like air foil and k&n's the 14.3 was @ 93 mph i replaced my cap and rotor since then and i am going to replace my plugs before the track opens so hopefully i'll run a 13.9

 

Over the summer, I ran a best of 14.4 seconds at 95 mph. At the time, I had the following on my '86 IROC:

- 350 TPI engine
- 3" Hooker cat-back exhaust sytem
- Hi-flow Catco catalytic converter
- K&N air filters
- Homemade ram-air
- Removed spare tire/jack
- Hypertech coil, cap, and rotor
- MSD 8.5mm wires
- Crappy ADS SuperChip (REALLY bad)
- Slipping TH-700 that died a week later

Since then, I've replaced the tranny with a brand new street/strip Pro-Built TH-700. I'm also in the process of porting my plenum, and I'm going to be making a custom chip this summer. I hope to be in the high 13's.

 

-hypertech thermo-master chip
-160 thermostat
-300+ accel race wires
-fee mods
-150hp shot NO2
-TPIS afpr
-TPIS airfoil

I ran a 14.4 with out the nitous.
12.9 with the no2, just got to keep remembering to take that chip out first otherwise KABOOM!

 

My '92 GTA did a best of 14.3 @ 98mph.

It had a TPIS air foil, Accel coil, home made cold air, and that's it.

It was dynoed on a Clayton dyno at 245hp.
