What Race fuels have you guys ran with good success?? Im running a stock motor with lots of air flow and front Rads and no thermastat. I have a racer friend is trying to get me to run VP C12 or/and Mrxo1. I would think they are both have to high Octane levels.. plus they are both leaded. I was thinking VP U4, U4.2 or U4e.. But looking at Vp's site the C10 looks to be the best choices..:confused:
Yes I know what octane means, and yes I understand running lower octane sometimes produces better hp #'s then higher..
Other info: running Road Atlanta July 3/4 which will be at least 95+ degrees..:eek:
