Been a while since on the forum. Figured I'd post numbers of the cav after running low 12 s for six years finally broke down bought a set of Hoosiers 245/45/17 and had few decent runs. Setup is a 2001 cavalier with built 3400, 60 degree turbo cam, scant rods, wiseco pistons, 3500 ported heads t67gj turbo 15 psi,55lb injectors, obx helical with upgraded bolts and debarred, spec stage 3plus with double diaphragm spring, mega squirt, alky injection. Car ran 11.7 at 124.55. I'm sure others have hit similar times but this is my daily driven streetcar. going into friends dyno next week to get numbers. It's a dyno dynamics, last dyno was about six years ago and made 373 on 15 psi with t3/t4 60 trim, stock 3400 heads mad smaller intercooler andnometh. Postin from iPad so sorry for any autocomplete mistakes I missed

Sounds like an awesome setup! I might have to forward this on to my dad, he has a turbo 3400 in his '88 Fiero.
