My vacuum at idle for 8:5:1 compression

I was wondering if 12psi sounded normal for an engine with 8:5:1 compression that would be 12psi at idle.?? Any inputs would be appreciated.

if your hitting 12psi @ idle you must have a very fast spooling turbo

shouldn't really matter what kind of compression you're running. vacuum should stay damn near the same compared to a stock motor. So yeah, around 20" should be right. You may have a slight leak somewhere.
