Felt like this thread is reasonable to post this. Ive been tossing around the idea of using an electric pump for crank case evacuation (sr20). I still want to keep the OEM pcv side intact. My idea was using a secondary air injection pump (they max out at 3-4" hg) that's triggered on a 1 psi pressure switch. So basically is idle/cruise the regular PCV will handle evacuation, and then in boost the PCV will close and the pump will take over. The point of the switch is so the pump isn't in constant operation.
