Thank you. I have never disassembled this unit. Is there a clutch of some kind between the input shaft and the impeller? The whole mechanism turns freely but I can stop the impeller and still turn the input shaft. Thanks

There is no clutch.
There is a planetary unit to increase the speed of the impeller relative to the input.
When the planetary is worn it is possible to turn the input but not turn the impeller.
In new or rebuilt condition that is impossible as there is considerable friction in the planetary unit to drive the impeller at speed.

Yes, the planetary drive is worn out and needs to be replaced. There are parts available from time to time. I rebuilt the one on my car, and it does make a difference in high-RPM power. You should not attempt to hook up the supercharger in the current condition because it could cause damage to the impeller and the plate beneath it. Of course these engines run just fine even without a functional supercharger.
