Looking to switch to cog setup for my NOVI 2000 Renegade. Lots of cog pullies out there for Vortech. I am have heard crank pullies are the same. Wondered about blower pullies? My blower uses a double keyway on the blower pulley. I know most if not all Vortech use single keyway.Will the blower pulley for a Vortech work.I know I could take it to a machine shop and have them machine the second keyway into the pulley. Please LMK if the Vortech cogs pullies will work. Thanks Chip
