Tunnel Ram vs STR
I think he meant that at some RPM point, being centrifugal clutch, it will engage. The comment was to have a switchable - electric solenoid to control pulley engagement. On - off switch like Mad Max. Not referencing a centrifugal supercharger.
If you follow Drag Week, at least one of the teams disconnects the belt entirely, has a secondary throttle body below the blower rotors on the back of the intake manifold and a tune for that combo... when driving from track to track. So, an electric engagement front drive, a secondary throttle body/tune daisy chained in, could really work....hmmmm
