North American Motoring - Drivetrain Supercharger Pulley Won't Come Off!!

I'm doing a SC Pulley replacement. Using the loaner tool from Webb Motorsports just for the stock pulley, and a crowsfoot puller. The pulley WILL NOT come off. I haven't broken the crowsfoot YET, but I obviously need a trick (and a prayer?!) before I do. I've tried a little heat (a little, on the pulley)...nothing. Tried a little penetrating oil...nothing.

I saw a thread where the pulley was cut off...with a steady hand on the air-powered cutoff wheel, using it at an angle, I suppose that could be done, but surely there is a better way. I searched the archives, and didn't come up with a definitive solution. HELP anyone?
