The roots-style blowers (any supercharger that is attached directly to the head) has a recirculation feature built into it...it's automatic.
Superchargers like a Vortech, etc, that are basically a turbo with a pully instead of an exhaust housing can either use a recirc-valve, or you can install an external blow-off valve. That's why you can hear blow-off valves when some supercharged cars are shifting...they are probbaly using a Vortech-type of blower.
