As with any high compression engine, supercharged engines require the highest octane fuel available to minimize any tendency towards destructive detonation. Camden Superchargers recommend that boost be limited to 6 PSI on an engine having a compression ratio of 8.5:1 when running on premium unleaded fuel of 92 octane. If your engine has a lower ...

Since higher octane fuels have higher activation energies, it is less likely that a given compression will cause knocking. (Note that it is the absolute compression pressure in the combustion chamber which is important and not the compression ratio. The compression ratio only governs the maximum compression that can be achieved).

If fuel octane is too low for a given compression ratio, the fuel prematurely and spontaneously ignites too early and the fuel charge EXPLODES rather than BURNS resulting in incomplete combustion. The net effect is a loss in power, possible engine damage, and …

Compression Ratio and Octane Ratings: What You Need to Know ...
The efficiency assumes that no other changes are made when the compression ratio is altered, such as quench, valve shrouding, piston dome masking, etc. and that fuel of sufficient octane is used to permit the best ignition advance. To use this table: locate the original compression ratio (“C-Ratio”) in the 1st, 3rd or 5th row across.
