RPM at the finish line is about 6800RPM. I probably have about 50-60 something 1/4mile runs on the engine so far. Like many have already posted, I guess its just a matter of time untill it implodes... /Tom

Vibration=chatter and broken tooling. S/F....Ken M the same type of guys wonder why you can't machine a 50lb. chunk of steel on your "atlas bench top" lathe, are in wonder when the chunk flies out of the chuck when the tooling grabs.....

Properly put together, maintained, kept fresh, and hopefully, live a long productive life. I'm definitely not in the "build, run it till it blows, rinse, repeat" crowd. I'm weird like that. If the results don't match the theory, change the theory.
