with a turbo "ping" correlates to $$$ more so than a NA engine. the ping you usuaully hear is detonation, when you start playing with turbo's you start dealing with the more deadly pre-ignition

9.8? i think i would stick with the 8.5

goto one of these sites that has an effective compression ratio calculator. play around with the static CR, boost and even intake valve closing time. i am not sure on this, but you might try to stay around 12:1. its pretty fun to mess with even if you ar not building anything.
