My engine has the compression set to 7.5:1. I have not experienced any
knock, lots of power and too much heat in the oil. As for my turbo setup, I
have dual egt, 4 CHT, as well as manifold pressure. To satisfy the thirst
of the turbo at high boost, I have a boost pump, which is a Facet pump which
I only use for takeoff and climb. After that it's back to gravity feed.
My carb is a revflow and positioned for suck. It is up front and gets ram
air. The distance from the back of the carb to the impeller is less then
12in. I have been using 100LL. My waste gate is manual. I'm considering
installing a BOV to prevent overboost. I could use a new prop to optimize
the planes performance.
