I found a slightly used renegade crank pulley for sale and picked it up. I am not going to change the pulley on the supercharger because I do not want to void the warranty in any way. What kind of boost/power might I expect from the 8" crank pulley and the stock blower pulley? BTW, I am probably not going to put it on for a bit. I think I can get some better numbers at the track the way it is and I want to keep it stock for a bit longer. The pulley was only 100 bucks and looks new in the pics, so I thought I might pick it up while I can :)
