On all my sports cars, big 8 or 10an PCV fitting into a catch can then getting drawn on either by the Turbo inlet pipe or on my GTO the intake pulls on it through the can. With my Talon I added a 12v electric Star Machine vacuum pump that pulls 10" at WOT and I might add this on my GN. That'll add 2% power and stops all leaks from CC pressure.
The GTO doesn't get any real vacuum at WOT so it's sort of a dead system that only the dual breathers help at WOT. Even those lame smog pumps pulling 2-3" would help here.
