Looking for the discontinued 6 rib pulley attachment that bolts onto the Supermiata damper for use with a wider supercharger belt. Anyone have one they want to sell?

I may be wrong, but I don't recall anyone making a 6-rib pulley attachment for a SuperMiata damper.

Way back when, 949Racing (when it was 949) sold the KW Rotrex kits for a brief time - that was still 4-rib. At a similar time, FM sold a 6-rib pulley for their ATI Dampers and BRP-based MP62 kits, but those died out really fast. FFS still sells 130/150mm sizes for ATI dampers, but you need to email Tom directly.

BHJ Used to make the sm damper and the sm sc damper. You’ll have to contact them directly if they still do.

Well, I stand corrected! Heck, you might even try calling Emilio and see if he has any laying around. I can't imagine many of those being sold. SM Damper + 6 Rib SC seems like a pretty rare combo.

We only ever made like four of the 6 rib pulleys a long time ago and they're all long since gone. You'll have to contact BHJ, we don't have drawings.

Also to clarify this you cannot simply bolt on the overlay to an aluminum hub spm damper. There is a steel hubbed damper for sc use. I hold one of these pulley setups myself and aided jtt getting his. Contact bhj directly. expect to wait a very long time to get this made if they even do make it again.

Trust me, I put the 6 rib over an existing sm damper and it’s a no go.

The underlying damper the overlay bolts up to is different.
