Spoke to the guy at MazdaSpeed  that is in charge of Star Mazda 240 HP RX8 engines. He showed me the dry sump oil systems they use in these formula  cars. They corner at up to 2G's using a lot of down force. The engines normally last over a years worth of racing (10 races).

The main problem they have is overheating and mechanical over revving.
The rookie drivers stick the transmission in the wrong gear forcing the engine to 12,000 RPM with out enough apex seal oil as it is mixed with the fuel. The fuel could be cut off. The EFI has a rev limiter under normal circumstances. Not a problem we have as the prop limits the RPM.

I am sending him a copy of my book How to Cool Your Wankel. The duct work for the rads leaves a lot to be desired.
