I have talked to Mini-madness and they have Pulley remover but you have to buy from there the pulley. After using the pulley remover you have to send it back ot the company
You can cut down one of the cheap aluminum mini puller types to close up the gap. Some pulleys are really on tight, yet others require very little force. I was able to remove a JCW with the cut down trick! The puller should still work with some longer bolts for the stock size. Just be careful that all force is applied between the front end of the shaft and the pulley itself. At no time should any force be applied between the pulley and the supercharger aluminum body or any side to side pressure anywhere!! It has to come straight off from the pressure to the tip of the shaft by the center screw of the puller. If you muck it up with a 3 jaw pulley puller you can drill and tap the pulley for some some 5/16 bolts and a suiteable puller.
