Compression
Yes, I would like to keep the compression low for a couple of reasons, it’s a Pro-Touring build that will be street driven and road raced. It’s hot in Texas and it will heat soak after running hard at a road course(even with as good a cooling system as possible). I’ll also open road race and averaging 130-135( depending on what class I enter) really taxes an engine going 53 miles(and 53 back) The second reason is the next step; a turbo system. With lower compression it will be less of a hurdle than exceeding 10:1. This ethanol blend 93-octane is not very good. On my 462 with 6X-8 heads I have to “spike” the fuel with Boostane to ensure it doesn’t ping in the summer.
