Just want to say whats up to every one!!!!
I own a 2007 base 3.8L grand prix and im looking to get a few more poneys out of it.. i figured i could just slap on a supercharger from a L67 but turns out i have a series 111 3.8L not a series 11 3.8L so that kinda slamed the door on that project and now need some advice on what i can do. im lost how the gt model makes 50 more horse then a base model.. i figure the ecu (20-30)hp and the duel exshaust only (10)hp if that cuz it just ''y'' at the back to two tips.. so what can i do to make my ride a bit more non old mans car???? im so pissed that the intake is diffrent and cant put on the supercharger.... i know its a strong 3.8L and has alot of history for making power but dont know where to start... any thing will help thanx....
