At 240-260 you should be making decent power, at 280 you should be screaming, at 300+ you should be crying and screaming.
Amen to that... tuning for performance is not for everyone. at what price are you willing to pay for performance is what you should be asking. common sense tells me that metals in general when you heat it up will soften and expand. at 280+any metal will soften up combine that with 43000 rpm+ you can do the math. my friend do what your common sense tells you. everyone here feels that their way is the way, rightfully so in some instances. just be careful..
