Compression on D before turbo

Just a quick poll of turbo D guys...

What compression numbers were you putting down before turbo, and how much boost are you successfully running?

ALso if you had any problems with this, specify

Thanks!

Re:Compression on D before turbo

that does not help me. I am asking for actual numbers from people who went turbo. Looking to figure out what is safe.
