I wanted to say thanks for the references and clarifying things but then I saw the "tongue in cheek" rubber band reference.

The other choice for SuperCharger is to use a modern day implementation of the system Studebaker used back in the mid-fifties, a variable ratio V-drive "CVT". Drive the SuperCharger from the engine but via an e/CVT differential. An AC synchonous motor driving the opposite end of the differential with the differential output driving the SC.

That way the positive displacement SC boost could be varied independent of ICE RPMs and therefore used in place of a throttle plate to provide whatever level of intake airflow was required of the moment. Slight/low intake flow for idle and then all the way up to FULL boost at WOT, NEVER OVERBOOST.
