Ok I think I'm better now, I was planning on going with either 10.0:1 or 9.0:1 compression, will either of these give me a significant power loss and if so what kind of loss? If I go with a higher comression (11.5:1) what amount of boost can be safely added and will this ratio provide me with any type of losses? Also on the lesser of the ratios what type of boost can be added?
