Help with street strip suspension tuning z28 Mods are--stock bottom end, AI 799s, AI 226/234 600/600 cam, ls6 intake, sd tune, ftp 98 mm lid, pace setter headers, custom 3" Y to 3-1/2" merge to single bullet. 175 shot on a nozzle.
Suspension mods-- strange sa front coil overs with 300lb hypercoils, summit rear drag shocks set at 50/50, mwc sfc's, spohn adjustable t/a set at -2° with the earth with the car at ride height (per madman)
Car is a hard top z with little weight pulled out, removed rear seats, washer reservoir, ect. Nothing major at all. Has race stars front and rear with 27x11.5 quick time pros. Th350 with ptc 3500converter, 3.73 gear.
I'm having trouble with the 60ft, on motor it ran 1.66 60ft, 7.43 @93.5 mph, no spinning.
on nitrous i can't get it out of the 1.6s. Best pass is 1.62 60ft, 6.94 @ 101.8. That was with 12psi cold in the Hoosiers. It was turning the tires over in first. I feel this car should hit 1.4s on nitrous? Any suggestions?
Thanks -Josh
