The reason they have to is because a SC is tied to the revolutions of the motor so it is basically making boost all the time. When you are at 7000rpm and let off the throttle, and the supercharger is still spinning at 50,000rpms....where do you think that air would go?

Even at idle the supercharger is still spinning and the air it is pushing has to go somewhere. The engine is set to ingest what fuel it is seeing for a good AFR so it cant keep swallowing air.


Every and all centrifugal superchargers are like this.
Chuck33079 and zmanelite like this.
