87_shee Posted October 23, 2008 Report Share Posted October 23, 2008 Well I recently changed to 20cc domes and Im going home this weekend to try it out. I'm expecting around 160psi, my Squish is .050 and I'm pretty much at sea level . I have talked to a few people with similar setups and some run race gas an some don't. So I picked up some C12 just incase. My question is can I mix it 50/50 with 91pump or do I run it straight? I'm sure someone here can point me in the right direction. Thanks Quote Link to comment Share on other sites More sharing options...
J-Madd Posted October 23, 2008 Report Share Posted October 23, 2008 CHeck compression to be sure. If it is 160, you may be able to run +4 timing and pump gas. I had a stocker with 155 psi and +5 timing and it ran great on 93 octane. Quote Link to comment Share on other sites More sharing options...

Yah Im going to check compression before i do anything, but even if i can get away with pump gas, I still have 5 gallons of C12 that I can burn, So will it hurt to run straight C12 or should I mix it 50/50?

THE GRIM RIPPER Posted October 23, 2008 Report Share Posted October 23, 2008 Definable mix that shit man. Get your moneys worth. You'll be fine, I run 20's at sea level myself and mix 50/50 with VP RED which is 106 octane I believe... Unless Im feeling frisky, then I'll treat it to a full tank of the VP :biggrin: Quote Link to comment Share on other sites More sharing options...
