JBP, what kind of gains can we expect from the lighter pulley, I know it will help to make the engine and everything work less/easier, but what kind of physical numbers could we expect or is that unknown at this point?
I'm with you Dan...
We should get another JBP Group Buy going on this ;) .

i thought i read some where taht we could not use underdrive type of pullys becase it would throw of the charteristcs of the supercharger and how the system works??? but i dont know? just somting i read on here but it would be a nice thing to have on some cars i have seen you can get up to 18 to 30% increase in power

The pulley should be the same diameter, just a lighter weight! So no characteristics of boost should be affected

cant wait until the crank pulley!
Yes, lighter. The diameter is the same as stock.
are the SC pulley's the same 5 bolt pattern as the one in the intense kits?
If they match the GM stage 2, then yes.

Gm stage 2 is a 4 bolt pattern. I thought you couldnt go lower then 2.8 on the gm hub..
