Passed on the catch can idea altogether. The Procharger fills the spot where the catch can would be mounted as show in No Doubt's photo.
Have opted to just vent the breather tube to the outside. The whole reason I got started on the idea of a catch can was that the Procharger was sucking oil/vapor out of the motor and into the throttle body. The blower began to drip oil as well because it was ingesting the oil/vapor too.
