It's neither of these pulleys. It is the large 90 mm flat (rides on top of the belt, not in the grooves) metal idler pulley below (not to the left of) the supercharger pulley. It is similar to the tensioner pulley over on the right side, but just an idler pulley to change the belt direction. It mounts with just one hex bolt through the center torqued to 15 ft. lbs.
