    My friends and I run 5 gal of C12 race gas (108 octane) with approx 10 gal of premium. No obvious performance gain, but it helps with engine temps and detonation.

    Brendan,

    I am considering this as well but going with a 50/50 mix. What sort of numbers change did you see in your A/F with this setup?

    I'm not sure about the a/f change. However, I would caution that too much race gas will really speed up the burn in the motor causing a DECREASE in hp.

    Jay,

    I did not check the a/f with the (specific) addition of the C12. I have been running with it all year though.

    Cool, I am hoping that deto on #2 will go away when I do this without fooling around to much with the fuel portion of the mapping on my EMS..

    My understanding is that many ems kits have deto on #2. Are you running lower comp pistons? S/b a big help. I'm running them even w/out the ems.
