As for someone who built their motor to 9.8:1 (Started with 9.5:1, shaved bown block), I can honestly say I really want more N/A power. It is a pretty sizeable difference for day to day driving, having the higher compression. The only problem now is that I want more, and am thinking of going up to 10.5:1. The "more quickness" (For lack of better terms) the car has pre-boost makes it much more addicting.

If I had to do it all over again, I would be doing 10.5:1. I switch back and forth between E85 and 93, so map switching would be a huge plus if you are looking to do that. With 10.5:1 and a stock(ish) turbo your pump gas tune should be spot on whereas E85 is more forgiving.
