our volvo's run 10.8:1 and 11.0:1 compression. I didnt think that was high.. ..but it sure likes 97-100 octane. At least that is the octane at which MBT with the most power.

as for your 40% number..is that from your experience of driving a car that has been converted or something you read on the internet, where all posts are intelligent and well thought out?

as for alcohol for drinking and gasoline for racing.....I sure hope gasoline isnt for drinking
