SuperMiata Harmonic Damper?

No one really knows for sure what exact level of power and abuse breaks oil pumps and for many years it wasn't even seen as a weak point.

A lot if track cars in Aus are built this way. I'm sure a harmonic balancer still helps though.

I don't... in fact I run a cut down stock damper to 8500+. The key is to bypass the factory oil pressure regulator and run an external peterson relief valve. It's not the crank deflection that kills oil pumps but the chattering and limit of flow within the stock regulator.

It may have started due to classing rules which are pretty stringent on engine mods. Talking to the guys running them it was definitely a known solution proved with testing and track time.

Interesting about the external relief valve, I like that.
