We just got off the dyno with a 2004 Grand Prix GTP CompG. Mods included INTENSE Stage 3 CNC heads and blower cam. Blower was a stock fifth gen M90 with 3.0" supercharger pulley. INTENSE Stage 3 PCM was dialed in with +3 degrees of timing, tuned for 60 pound fuel injectors and 85 mm. LS1 MAF sensor.

Best pull was 322 WHP on pump gas, through the full exhaust, with 93 octane Shell gasoline in the tank! I would estimate that a good intercooler would permit the 2.6" pulley to be run on pump gas and produce ~ 340 WHP. With race fuel and more timing, 350 WHP should be achievable through the full exhaust system.

These are STD corrected numbers (actual was 333 WHP I think).

Congratulations to John Kuehner from Texas!

Damn very nice numbers indeed. How much boost was pushed through? Got a pic of the dyno, I definitely like to see how that curve looks like.

Nice run John (Chris, Scott and others involved)! You've finally proved to me that that car actually runs :D. I suppose we'll have to wait until spring to get some track times huh? '04's rock baby!

Is there no racing in Texas during the winter?
I believe there is...

I'd like to see the dyno charts from the stg.3 cam.....
We plan to have an intercooled Stage 3 heads/cam/PCM 2004 CompG on the dyno within the next couple of weeks.

Was the TB worked a bit with the LS! maf added?
No, the throttle body is still stock.
