blow off valve... The diverter valve would normally recirculate boost pressure back into the air box (where it is unheard on stock set ups). the valve opens when off throttle to release boost pressure from the system, it closes to create boost when the supercharger is engaged. had a similar set up on my car. except I had a complete custom supercharger inlet that I had made and ran 3" intake pipe from the cone filter to the supercharger. sounded dirty!
