I Have. They do not make that Crank pulley anymore and said for them to make something compatable will be about $1200. I think thats a little Outrageous.

So is it different from a normal v belt crank pulley with the 3 grooves?

TBS shows a 10 or 16 rib pulley. Could you use that or would it make sense to go with cog belt and get new pulley set?

The original crank pulley is a 10 Rib for the supercharger. The diameter of it is 8.75 inches. The problem is trying to get something that exact size. If the diameter is less the supercharger will produce less boost. Then I will have to go back and swap out the supercharger pulley to one that is a smaller diameter to bring the boost back to factory specs. I have thought about switching over to ACOG bye it’s actually sticks out farther and I will not have the clearance for my hatch for backseat location
