tIANci,


Probably not, but these engine last for an eye-blink; usually 3-10 hours, when a properly broken-in ABC airplane engine, will endure about 100 hours, before needing to go to the cleaners...

Coincidence?


I believe very high RPM car engines, should be temporarily propped (toothpick racing prop of the appropriate size, of course and a 'normal' cylinder head...) and broken-in like airplane ABC engines.

This does not apply if a certain engine has a ringed piston (which NEEDS a cold, rich break-in).
