I know the 5% jackshaft pulley's are made out of aluminum which makes it lighter than the O.E. jackshaft pully but what is the advantage (if any) of a 5% jackshaft pulley over a 5% supercharger pulley as far as overdriving the blower is concerned? :)

The biggest advantage is no belt slip. :) The weight reduction is a bonus. You can run a 5% jack pulley and 5% blower pulley with a stock belt and NOT have ANY belt slip at all. That is the nice part. :)

It is so much lighter that you wont believe it.

I couldn't believe the different in weight and i only got the stock ratio. You can easily tell the difference. I got SCI pulley, which was just about too nice to put on my car (i hear bill's is just as nice). :) It was well worth the money and a good upgrade.
