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.
The chapter on fuels and oils in Tom Sheppard's VDE Guide is pretty extensive. Have you ever tried this book?
