With CAI & tune, cams, LT's, 1 piece aluminum DS, UDP's and few other things I missed (plus suspension to hook up), you may be able to get about 350 RWHP while maintaining reliability and as a DD. A little additional weight loss and your power/weight will improve beyond the + that it already is. If you want serious power above that, then you'll need to SC.

+1000 (really +1 but 5 character minimum)

Just supercharge it and call it a day.

433 seems very high my Coyote is doing about 395 at the wheels. Only thing upgraded on it was exhaust. Have not done a CAI or the Boss Intake yet but even after that ill maybe be around 440 to 460 at most. That is without any supercharging so an 06 GT doing 500 with bolt on mods no way it's going to need some super charging for sure.

It's very easy to mod the hell out of a Grand Prix GTP, they are plenty of 10 second and faster ones. The respond very well to mods, the 3800 supercharged motor is pretty good, 433whp is very easy.

Back on topic I guess good luck getting 500rwhp or crank out of a 4.6, while it may be a great engine boosting is the only way to get there. I do love the sound of a 4.6 though.

You can get 500RWHP without a supercharger. Hellion makes great turbo kits. Seriously you can but it would require, a completely new engine consisting of a block like the FRPP stroker block M-6009-A46X, ported heads similar to M-6049-463VP3 and custom grind cams so aggressive you would lose VCT funcionality. Not worth money and loss of streetability.

Do you really want to put yourself in financial hardship so that you can win a few races? Why? Who is that going to impress? A bunch of dudes with grand prix's. Literally nobody is going to care other than said dudes with grand prix's.

Clearly the best solution here is to just not race them and enjoy your car and your money that is sitting in the bank. Chicks dig money and S197's bro. I've never seen a girl go crazy for an old grand prix that's torque steering all over the damned road.

Well said!

You can run 12s in the quarter with common bolt ons without touching the engine. That's enough to handle most grand prix. Especially from a dig.

If you want 500rwhp without boost, you're gonna need this:
