I personally would not use a pcv on a supercharged engine. It creates a vacuum leak to the manifold and that vacuum is pulling oil vapour laden air into the engine. This lowers the octane and increases the chance of destination. Just a bad idea in my mind.

Scooder, I spoke with someone here on the Barn that runs them on their blown motors with no problems noted. I'm still listening to what you have to say. I found out that I'll be running the PCV to a port that's on the carb. It's a Holley 1850 600cfm. Will this still cause a vacuum leak problem?
I'd love to hear from the blower people if they use a PCV system or not!!
Thank you
