i did that on my acura when i turbocharged it. It worked pretty well. Good for scratch built turbo. BUT.....i am really not sure if this would work for German vehicles. Theory is the same, but not sure......


Hope someone can give you the answer.

8 psi and you should be fine.

Anything over that and you should start looking into a 3mm head gasket.
