A supercharger will weigh more than a turbo charger for one thing. And just to pass along my experience...I've blown the Teflon seals out of two B&M superchargers, and we blew the gears out of a new Camden and it seized up this year. I dont think I wouldnt want one on my plane. Now one of those paxton type might be ok, but it looks like to me a turbocharger is just built for rotor motors.
