Hey dose anyone know how much rwhp a 99 GT can take on the stock internals? Right now i have about 413 rwhp and im dieing to make it faster but cant spend the money for an engine re-build. I herd about 420 horse is the max i can go, is this true?
Also someone told me to shift at 5k rpm's cuz theres to much hp for the motor as it is, is it ok that i red line it? or is shifting at 5k a good idea?

Thanks for the help
Joe

Joe from what i hear, every motor is different, some guys go up to 450 but its only a matter of time, also the tune has a lot to do with it as well. Good luck with the motor.
