Dragging this thread back from the dead...WARNING!

I recently purchased a used FocusSport Vortech/VF supercharger kit and I am planning on installing it within the next couple of months. My question is regarding this pulley...

My kit produces somewhere in the neighborhood of 9-10 PSI on a stock pulley. What kind of increase of boost would I be looking at with your larger pulley?
