If you are running race fuel, I was running Sunoco Supreme 112. I don't know about alchohol because I have never used it. My motor was 13.8 and on the dyno I used 114 and 112 and the 112 made 8 more hp.
What type of fuel are you people using or recomend on 14:1 632ci combo?
How many galons are you burning during a burnout and a pass?
We've used 112 and 114 both on bigger CI with 14.8:1 compression and see no difference so we went back to the 112. With gas you usually dont use much, maybe a gallon.
Thats including the drive back to the pits. Is that still to much??
I'd say so, I drive mine up to the lanes (I park usually last car beyond the 1/4 mile so its a drive) make the pass & drive it back and still dont use over 2 1/2 gallons.
