Thread: Safe Boost Vs. Octane

    With a 10:1 engine SBC, Alum. Heads, Fuel injected, what is a safe boost with 92-93 octane (intercooled Procharger System), how about 104 octane. How much would the timing need to be retarded?

    With that much compression I would run it on alki myself. To much for gas. In a few posts down HeavyHitter talks about retarding the timming. You should read it. I, myself like his thinking.

    Geoo,
    I would not exceed 3-4lbs. on 91 octane, no more than 28 total timing. That's very high compression and it's hard to shove anymore air in there. With 104, you can probably get away with 6-7lbs. Just my thoughts.
    Thanks,
    Dustin
