Yeah Mark!

I never had a piston fail from detonation but when that needle goes past 8,000 RPMs- real bad things happen to piston skirts. LOL
LOL, you have to have run more piston to wall clearence if your spinning it that high, to tight and and they will melt with the boost and juice. i shift mine @8600 and no problems. PM me see you soon.
