Thread: Clutch slip?

  1. #1

    Clutch slip?

    Anybody ever heard of a supercharger not putting out full boost when slip set high on a 137+4? Set to almost no slip to test. 148 inch pounds.

    IMO that slip is a little to low..I would set your preload your slip around 190 inch lbs.(for 8100 RPMs).Also make sure your fan isnt spinning on the shaft...

    Sno is right. That is a little low. What other supporting mods do you have to go with the SC?
    I run a 137x4 in my conversion and we have the slip set to about 15 ft/lbs, which is about 180 in/lbs.

    Do you have access to some L collars? Sometimes you need to find one a little longer. There was a guy on here awhile back that was making them in different sizes, so you could get your slip just right without using shims. I wish he still was making them, I would buy a set.

    Ok I will try the different configurations of spring washers.

    I only have the two L collars, old and new. Will measure them as well.

    Thanks

    If you find you're at 18ftlb try sanding down the L collar to get your desired setting.
