was wondering, what it takes to make a rotary capable of 12000 rpm's? how about 14K?



what parts are needed, and anyone got links to buy them?

Carbon seals, Lightweight and balanced Rotors, Oil/Lubication upgrade,

Deep groove comp. bearings, lightweight flywheel, fully balanced and blueprinted motor, Free flowing Intake & exhaust systems with no defects in workmanship. Would be a good start.

extra clearance on the tip-rotor and i think corner seals too

why would you need 14k rpm?

the reason being i had awalys heard rotarys were some kinda monster revvers of hell. and it isnt really true.



i dont consider 9K high revving, i left the vw world doing that.



soz if im going to build me a rotary, i want it to be what i had awalys thought it was, some high revving 2 stroke like engine.



also, anyone make ball bearing eshafts for a 13b? i know they can be had (although rare) for a vw, and in crankshaft form.
