Just wondering what the max HP is on 99 Cobra with stock internals?
03 mach1 here with 466 rwhp. had s.c. on since late april. I've been in the boost alot. And had no problems yet. Met a guy at the woodward dream cruise running 520 rwhp on a stock motor for over a year. I think it depends how its driven and what kind of power adder you use. turbos seem a little softer and twin screws seem a little harsher on the motor.
What tune did you use?
