I was thinking about getting the UD pullies as right now they would be easy to put on. Then I heard that they have to be removed for a supercharger which would make them a waste. Would that be the case with a Kenne Bell?
Don't some superchargers use a separate drive to drive the supercharger? If that is the case, the UDPs wouldn't affect the supercharger. I'm not sure on this, though.
I think that Kenne Bell will build custom pullies. I am planning on getting a Kenne Bell in the future and was going to ask them if they could machine an oversized pully so I could keep my March Pullies. It might be something you could check into.
