Petrol & octane problems
anyone used a Land Rover V8 with the 9.35:1 compression ratio in a country that has low octane fuel (typically 83 RON)?
My v8 has the composite gaskets that are twice as thick as the standard ones, effectively lowering the compression ratio a little - I've been told that the CR should now be about 8.8:1.
I'm looking at retarding the ignition and maybe using an octane booster to keep pre-detonation in check. The octane booster only makes up 2 points on the RON scale, so an 83 octane fuel would become an 85 octane.
