Pontiac G8 2008-2010 - Procharged G8 New Dyno Numbers: Blower Cam + Fuel System + E85

I'm really happy with the results. The tuner ended up de-tuning just a bit because of pushing too much boost on a stock bottom end (about 13.5psi of boost). Changed the pulley today to drop 11psi of boost to be on the safe side. The car is ridiculous, no traction whatsoever... I think only three dyno pulls were made, on the second pull if recall correctly the car made 747rwhp, just before the tuner tried to reel it back in with no timing... LOL! Finals numbers are 709rwhp with almost single digits timing advance.

That's a spine chilling power number!! Wow and wow.:)

So 747 rwhp was @ 13 lb of boost? Wow.

Yup, that and some timing...

Very nice numbers. I cant wait to get a Procharger. How is your trans holding up at that power level?

Me neither. :) That was only one dyno pull though, we ended dropping the boost to be on the safe side. No heads work has been done.

Unless you decide on new springs, valves, pistons, and rods/rod bolts. ;)

You sir are a braver man than I. My car sits a 551whp, I'm just a fuel system away from 650, but the question is, do I really wanna go there? Congrats on the beastly numbers. Start putting money in the kiddy for a tranny rebuild, diff, and axles.

I'm going to kept my eyes on your posts. I'm itching for the extra hp just affraid the extra $2000 for the power is going to cost me an additional $5000 to contain it.

Dang. This makes me want to buy a G8!
