    Difference in teeth count from old supercharger idler to newer...

    Anyone know the difference off hand from the original idler to the newer style?

    I tried to use the search function but I cant find anything that answers the question....

    My idler has 50teeth and my clutch has 60teeth from an 09sho.
    Anyone knows if my clutch is the newer version or the older? (I didn't buy the ski new so I don't know if it was ever replaced)

    After pulling mine apart yesterday and counting I also found that the small gear on the idler is different as well. One has 19 teeth, the newer version has 18 and both of the big gears are 50.

    mine is still going strong at 250hrs. But thanks for confirming my model so that I would know what to change if it fails.
