That would probably be better with a roots positive displacement supercharger. But a clutch would definately be needed.
But again we're getting back to the twin-charger discussion.
What about a mini gearbox inside the supercharger side of it? If you can get 2 or even 3 speed transmissions for 1/10th scale remote control cars, then its possible they can be that compact.
Do centrifugal superchargers have an efficiency rpm or an efficiency boost pressure? If you could build one that could keep spinning but not produce any extra boost (what does a supercharger do outside its efficiency range?)....
I'd imagine the power curve to be similar to Norbie's twin turbo curve, unless you got the supercharger/turbocharger matched up just right.
