I know in the 1960s go kart racers would modify their Victas and get anywhere up to about 16'000 rpm out of them.

Thats with a custom made head, porting, case stuffing, big carb and a megaphone exhaust. Standard rod and cast Aluminium flywheel. On the lawnmower they originally came off they did 4000rpm.

While a few flywheel explosions did happen it was much like the clone flywheels thing, one in a million.

I think we're pretty safe, just don't treat your flywheel like crap.
