Phil,
run a rally car / WRC car on normal Super-unleaded and see how long it lasts . IF pump fuel was as a higher octane, I would gladly be running higher compression, as it would be a win-win situation. Unfortunately it isn't. It is much safer / better more power to run low compression high boost then having to run the retard you are running to allow the boost you are running. Perhaps you should stick an EGT gauge on your car to frighten yourself .
