wouldnt higher octane fuel burn faster? the more the octane the more BANG the camber will have therefor piston will be pushed down harder?
and also another bit i don't understand is a engine running lean will run hotter, but when i adjusted the mixtures to run perfect the temp went up? WTF :dance:
i think fuel burn time has something to do with it, so run 10 - 12 degrees with 95 octane?
For everyone who doesnt really understand a cars ignition keep reading
with the workshop manual it says 6 degrees advanced with a minium of 90 octane fuel. Lets Say : piston is 6degrees BTDC, air/fuel is ready to be ignted, so when the air/fuel is ignited the piston will be 2 degree before heading down, there for will be induced a knock.
(was getting BAD knocking with 91)
same scenario but timing slighty advaced - lets say the piston is 3 degrees BTDC, air/fuel is compressed and ready to get ignited, now when theres ignition piston is 1 degree before heading down. now that theres higher octane fuel in the engine it will be burn quicker therefore pushing the piston down just as fuel ignites,
hence more power and no knocking
