If you are at 160 to 170psi you will get detonation with 93 pump gas. You NEED to run 110 or at least a mix of 50% 93 pump gas and 50% 110 race gas. 155psi is the compression limit for normal pump gas. Anything higher than that and you need to be running higher octane fuels. Quote
Ducman Posted August 30, 2006 Report Posted August 30, 2006 Its the opposite of what your friend said. Too much octane is fine, just a waste of money unless you like the beautiful fragrance of race fuel, not enough octane and it will destroy your pistons. With your compression you should be running a bit more than 93 octane. A 50/50 mix of 110 race fuel and 93 pump fuel will get you 101.5 octane which should be plenty for 170 psi. Quote
