Charles at Magnum Powers made me this a few years ago. We were shooting for a 20% jackshaft pulley, but I believe this ended up at 15%. He only made 3 of these. Due to the larger size of the pulley the actual jackshaft bracket had to be modified as well by welding up the original tensioner bolt hole on the jackshaft bracket and moving it down to accomodate the jackshaft pulley. I am including the modified jackshaft bracket as well as shown in pic. This larger pulley helps prevent belt slip and increased overdrive without having to move to a very small blower pulley which tends to slip.
