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 )

I think it was an Exxon station but if anyones interested I could double
check.
