Race gas vs pump gas on lower compression street/strip motor

Opinion:

The higher the octane the slower it burns.
Race gas in 10 to 1 or lower compression Will cost some HP, burns too slow.
But ... Motors like the lead :)... Cats don't :rolleyes:
I'm 'happy' mixing Leaded AV Gas 100 and 87 UL pump at doses of 50/50 at 10.5 to 1
Some alcohol could actually be helpful in passing water while you're 'passing gas'. At <5% in the above mix not much concern over the Crusty Carb Syndrome while sitting.
