    i am running an ET 137 +4, on 98 octane fuel to 8650.

    I have a rude 3 i want to try, and then up rpm to 8800. i was told to run 98 fuel still, but add some octane booster.... hopefully it is a safe option

    Do the guys running the bigger ET chargers really use race fuel?

    Like IronHead says just crank up your rpms bro. Pick up a 9.5 or 10k ECU and spin 9k plus.
