Default How much compression is to much for a turbo

Just wondering how much compression is to much for a turbo? I have around 13.8 to 1.

GMAN005, Not worth installing the turbo on the engine with that compression ratio.

Unless you want to run methanol and less than 10 psi of boost pressure.

But you would have the "cool" factor. You are a racer, not a Dairy Queen cruiser.

I’ve heard that many of the really fast guys run high compression (13-1) and e85/m1 but I wouldn’t try it. They have tons of time and money to get it right.
