Current break in wheel HP Dyno sheet @ 11psi for the early Jarvis motor. Too bad about your piston and with mine bending a rod. I hope both yours and mine will be good for a long time. I suspect with mine a tuning mishap, maybe a previous tuning may have been your cause also. Hope you post your results. Is TurboKraft doing more head porting etc, from original Jarvis build ?
