Question good folks:

When equipped with a Blow Off Valve (BOV) with a supercharger (A and A e.g.), when the supercharger is NOT making enough pressure to overcome the vacuum in the manifold, does the BOV suck air IN to the intake manifold?

Thanks!

On the nicer kits the BOV is bolted onto the intercooler. When your not into boost it is releasing the pressure, so its blowing out.

No, the spring keeps it shut.

It will never suck air in, there's no need for a filter (if that's where you're going). Filters do minimize the sound of the BOV though.
