    B&M 144 SBF

    How many ribs does the serpentine belt for this supercharger have? Looking at buying additional pullies. Also, I have the 6 lb. pulley that came with the supercharger, what size is it so I don't order what I already have?

    Thanks,

    You can count the number of valleys between the ribs on the pulley. I haven't seen one of these setups up close but I'm going out on a limb and assuming the blower is driven by the accessory belt in which case it's a 6 rib belt/pulley setup. So you would want a 6 rib pulley. Measure the diameter of the pulley to find out what size it is.
