Can anybody help out here!!!!!!!!! I wanted to install the blower this weekend, but the only pulley I can get is a 4-inch right now...I can't find the 3.33 inch 8 rib pulley anywhere. I want to run 6-8 Lbs of boost...the pulley thats on it now was making 12-13 LBs on a 347, so thats no good for what I want out of it
