nice unit, andy!
I was thinking of converting the existing air pump in front of the driver front wheel to run at all times (switched 12vdc) and plumb the crankcase to that pump. Then fix the accompanying codes, of course.

The PCV system applies a slight vacuum to suck put any blow-by that got past the rings, leaving the pressure inside close to atomspheric (I'm guessing). The engine's gaskets are designed to keep the engine's juices inside, not hold pressure. Will they hold up, or do different gaskets have to be used? And how much HP does this pump use up, anyway?
I've tested this product for nearly a year and the gaskets and seals are fine. If you have an application that will be pulling plus 30", then you need double lipped front and rear seals. We sell those as well.
The pump consumes 1-2 Hp to operate but will pay that back.

Not a bad idea but once off idle there isn't sufficient SCFM from that air pump.
And, to give you an idea of the electrical power required to maintain 14" of vacuum @ WOT, you need about a 1 HP DC motor and that will pull over 60 amps!

Oh, is it a vane type pump? Looks like one to me.

Have you folks tested this on a car that see's lots of road course track time? I'm wondering how well it will last at WOT for extended periods.
I just upgraded to a 383 and have had issues with crankcase pressure, looking for a good solution, and this is the best I've seen so far.

WHere would it be mounted on a S/C application like mine?
