Default Crank Pulley help...

As you all know I ordered my SC-Trim Supercharger. And I have a feeling that 6PSI isnt going to be enough to satisfy my needs.

So my question is this, I heard somewhere, where I can up the boost by changing the Crank pulley and not void the waranty on the Charger.

Ive been searching for the past hour for a 6 rib crank pulley to do this but I cant find it anywhere.

Can someone help me find it? Or have a part number?

First link is to for a 8 rib blower pulley and 6 rib accessory drive. Is your blower 6 or 8 rib?

Second link lists it will make 12psi with a 2.87" blower pulley. What size is the stock blower pulley? I thought your kit had a stock 6.87" crank pulley. If that's the case, you'll only gain maybe 1psi.
