02KBGT

Im running my kenne bell at 9psi on my 02 GT and my car has stocks headers exhaust (no cats) cams and heads...im kinda scared of messing up something with the stock internals..my mechanic says the motor will hold up..hes done it before with no problems..but i need outside opinions..

i know he knows what hes talking about cuz hes built multiple 7. 8. 9. sec cars and has more years under his belt than i have been alive lol..but if anyone wants to chime in and gimme their opinions ide appreciate it..thanks

Your car will hold up fine with the setup you have now. You need to start worrying when you get to the 430-440 mark.
My friend blew his up right around 430.
