I adding the Stillen Supercharger and I have an Unorthodox main drive lower crank pulley. If anyone is interested in trading their oem lower crank pulley. I'll trade even for it. Supercharger requires the oem pulley.

You can run the stillen with the UR but your boost will be lower. Try to find someone local.

 

where are you located

 

Moved to the forced induction section. If you're looking for a trade or are wanting to sell your current pulley, post in the classifieds section.
