Let me throw a monkey wrench in this discussion.
WWII we used 145 octane in the Merlin and could pull 61 In. Hg. P-51's flying today only pull 55 In Hg due to only lower octane fuel available. We got more HP/torque (what ever) with the 145 vs the lower octane used today. (I know the answer do you?) Now a War story. Some of our 145 octane fuel went bad for aircraft use and they mixed some oil in it and sold it in the PX for auto use. I drove from Kyushu to Tokyo on that fuel and going up and around Mt Fuji I had full throttle and the old straight 6 cyl Chevrolet engine was smooth as silk at 3 mph in high gear. Octane will really do wonders for you ![]() Big John On Fri, 09 Apr 2004 01:17:22 GMT, UltraJohn wrote: One of the gas stations I frequent in my work vehicle carrys 110 leaded auto gas I thought this was interesting and maybe of use for some with high compression performance planes (racers).
