no, same belt as the timing belt. but id imagine the older gilmer style (flat teeth) would make some noise.
oh wait. superchager belts have a flat tensioner wheel running over the teath side, not the back of the belt. hence the noise.
next issue is the crank trigger... not using the cas for rpm as its to unstable. just need a 7" trigger disc. btw, how many teath should it have? (counting the missing tooth.) any multiple of 6?
