So Dave Datsun what makes you a car expert?

I build and race motorcycles. My current bike is a Suzuki GSXR 750 with Carillo rods, Cosworth pistons and a bunch of other modifications. It turns 14,700 rpms, reliably, and makes 165 HP out of a 750cc.

I know what ping sounds like. If it doesn't ping at high load, low RPM, then it won't ping at high RPM, low load. That being said, if I hear/heard ping, then I would either change the gas to a higher octane, or retard the timing to an appropriate amount.

You are probably one of the fools that uses high octane gas in an engine that will see no benefit, because you think it will help your performance.
