PCV Plumbing with Torqstorm supercharger
I don't know anything about that setup but you CAN NOT plumb ANYTHING that needs vacuum TO THE INTAKE manifold, with a blower/ supercharger/ turbo. It must be a vacuum source, and if there is none on that setup you will have to use an external pump. This includes vacuum heater controls, etc
On a blower such as a 4- or 6-71, you could plumb vacuum accessories to the base of the carb, as those are "suck through."
I've no idea what to tell you about PCV Are you old enough to know about "road draft" crank case venting systems on older cars? (pre about 63 or so and earlier)
