Trial Formula – GM High Tech Performance January 2002

Seems like a lot of people build up Firebird Formulas, both because of their looks, and also the weight vs. a Trans Am. Here is one that runs in the bottom 10’s. With a 406 ci Motown block, AFR 210 heads, Comp Cams solid roller, Miniram, a T-Trim Vortech pushing out 14 psi, a 5500 rpm converter, and a 9″ with 3.70 gears it has run a best of 10.0 at 140 mph; making about 625 RWHP in the process.  Enjoy!

IROC N Roll – High Tech Performance May 1998

Some of you may have heard of Preston Smith and his 9 second IROC – here is an article on how he pushed his car into the 9’s over the years with all the combinations he tried. The 9 second combo consisted of a 305 with forged internals, TFS heads, roller cam, ported factory intake. Vortech V-1 pushing 25lbs of boost through a home made air to water intercooler: 9.95 at 135mph! Enjoy.

Whammer Jammer – High Tech Performance March 1997

Here is a writeup of a guy out in the midwest who transformed his 16 second L98 GTA into a 10.6s 128mph monster while still utilizing a stock style TPI intake setup. Goodies include a built 350 ZZ3, vortech s trim with 17psi boost, 100hp nitrous, Dana 44, and a built 700R4. Nice!

Power Boost – Car Craft November 1991
