Ideal compression ratio with a turbo

Hi guys, figure this is the place to ask. I have done some reading on this and there is a lot of theory on it, but I am looking for some real world experience on this subject.

I am sure there is flaw in my logic here, but I would like to keep as high a compression ratio as possible to keep the engine peppy when not boosting but of course trying to stay clear of detonation under boost.

What is the batter way to go here? Lets say there is detonation problems at the following thresholds: 7.5 to one @ 20 PSI, or 9.5 to one @ 15 psi? ( I'm just throwing these numbers out as an example.) which of these would make more power without hurting anything?

Again any real world experience would be awesome. I don't mind playing around with things as far as tuning to learn something, but if I build an unworkable C/R into my 200, it will be very difficult to change it.

Sorry if this has been asked before, but a search turned up very little. Looking forward to any responses.
 
I think one way to keep a peppy higher CR and boost would be water injection. I know it can be a pain to have another reservoir to have to fill, but it keeps the detonation down.
 
Yikes, just pasted this to the "Turbo" section with the intent of deleting this thread to try to get an answer on this subject. Now I can't figure it out perhaps it has to be done by a mod? Sorry guys, I know the double posting thing isn't cool. Wasn't aware I couldn't delete a post I made.
