I think this would very well work on the VR4

Any Cog for the VR4 is a good choice and was even recommended back in the 80's by Paxton. I seen this Pulley drive clutch at SEMA and it is a nice product and was tested at 3 times the recommended rating of any Supercharger made to date.

I wonder if properly modified to accept a 10 rib belt if it would reduce belt wear.......Hmmm

Will this fit our vr-4? Anyone know a price?

nevermind, looks to be almost $500 from summit.
