    If you had the rotating assembly balanced out better than the factory does(factory balances the rotors with the counterweights in the flywheel like a wheel on a car, but the front and rear rotors and their respected counterweights aren't balanced for each other across the length of the eccentric shaft, and little things like the mass of the seals and such aren't taken into consideration, it's still good enough for the Rx-8 to hit 9k, but not 11k and up), and ran hardened stationary gears, as long as you could feed it oil and gasoline and cool it down it would keep revving yes. Ceramic seals that wear/weigh less and produce less friction would help too.

    ^^ Yeah, I drew a frame of a man running on each fan blade. That is him running at idle

    so pretty much as long as you could get the engine balanced out good enough and get the proper cooling then it could pretty much rev to the moon?(exaggeration, yes, but i think you get what i'm saying.)

    well you'd eventually reach a point where the flywheel and clutch wouldn't be able to take the stress of rotating and they'd shatter, but yes. There is a 3 rotor FC on youtube with a redline of 16K RPM. It's called the MPS Rx-7.
