Before I set my compression ratio I wanted to know what some of you a running. I'm going to run the turbo and from I can gather it's to be set at 7 to 1. I'll be running avgas as I've been using that in my Kitfox since they started adding ethanol in auto fuel.

Check the manual but if you are going to run only avgas then the compression would be 8 to 1. I run auto fuel (alcohol free) so mine was set at 7 to 1 both normally aspirated and now as a turbo. The turbo has nothing to do with the compression but rather the detonation potential of the type of fuel.
