I have a 91z 305 5-speed w/3.42 posi rear. I have a Performance Resource chip, B&M ripper, centerforce D/F clutch, SLP full exhaust(cat-back and 1 5/8 headers), msd 6al and timing control, k&n airfilters and a NX dual-stage nos kit. I think im gonna use 100 shot for the first stage and 50 for the second in third and fourth gear. What times do u think i can expect w/this setup?? Do u think there is alot of time to be shaved off by doin the free mods? I got 14.7 w/just the chip, cat-back, clutch, and shifter. Thanks in advance Derrick

 

12.9x's at 106mph to 13.0x's at 103mph is my guess depending on weight and launch technique.

Thats using both stages.

Remember 305's have itty-bitty combustion chambers that are prone to detonation.

You better fuel that N2o system right or you will be scattering your motor all over the track.

Good luck

Anyone else...please-oh yeah and ttt. Derrick

 

use the 100 shot in first gear and then switch to the 150 in second-4th. I would put a clutch switch to shut off the juice when the clutch is depressed. my guess on time depending on launch is 13.2 @ 106
