Gentlemen,
My experiance has told me to run either CAM2 race fuel or VP Racing fuel. Both have worked very well in my dirt bikes and several racecars that I have built. The racecars had 11.5:1 comp and no nice new electronics to help out just old electronic ignitions and carbs. I hope that you can find this stuff. Recently I've only been able to find it at the race tracks. What about aviation fuel, that has very high octane. But I don't know if you can use it in a on road car, legally or safely.
