Description
 
15% Overdrive no longer available in 8 rib kit.

*Now includes ATI SFI approved balancer as part of the package*

The ultimate solution for making power with your supercharged 5.0L. We have engineered the only available 8-rib conversion and OD balancer solution for the VMP, Roush, and Whipple 2.3L supercharger kits that use the rear shiv or 1st belt shiv on the engine (closest to the block). Due to casting variances, machining-down of your Roush nose drive (black portion of blower) may be needed to accomodate 8-rib pulleys.

Our kit includes:
  • ATI balancer 918047N
  • VMP 8-rib 5% overdrive pulley ring with 3 bolts and washers
  • Low profile water pump pulley with rear lip removed for clearance (same diameter)
  • 8-rib AC pulley, nickel plated, with shim kit
  • 8-rib ribbed ""spider"" idler for tensioner with HD bearing
  • Lipped Idler pulley (lower position on FEAD, behind water pump)
  • Smooth Idler pulley for upper FEAD bracket (75mm, 90mm, or 100mm, your choice)
  • 8-rib belt K080816 for 5%
*SC pulley purchased seperately, 8-rib blower pulleys available in 82mm, 75mm, 69mm, and 63mm (VMP blower only)

Installation is as simple as swapping all the included pulleys. Grinding of the front cover must be very good, and in the case of the upper boss and ribs, flush. The AC clutch should be shimmed .015-.020"" of clearance, basically where you have to rock the cover back and forth for it to touch the face. There needs to be enough room for the face to get a running start when the magnet powers up and pulls it towards the AC pulley to engage the compressor. The ribbed spider idler is installed with the snap-ring facing out or visible.
