I think the factory backing would go to something that resembled the factory superchargers, I don't actually know if the GM, Ford and Mopar stuff all run the same brand or not.
I would think that there would have to be a Comp Eliminator class created for the current P/S cars to go into.
It's a millionaires sport right now, but with the changes that Allen Johnson proposed, you may see more guys like Charlie Westcott competing more often.
