Description:

• Lingenfelter Performance Engineering 2.60" diameter, 11 rib two  piece 10 bolt LS9 supercharger pulley in stainless steel

  • Two piece design allows easy changes to other  pulley diameters. LPE also offers a 2.35"  diameter pulley so you can easily further increase boost for at the  track with a  simple pulley change (belts and idlers may also need to be changed  depending on the application - click here for pulley and belt length chart for the LS9 engines)

  • Requires LPE 10 bolt hub kit (no included) - see  our other listings for this item (or  click here)

  • Here  is a link to the hub kit installation instructions. Be sure to make sure you feel  comfortable doing the work required to install this pulley BEFORE  placing your order. Installation requires pressing off the old pulley  and pressing on the hub. You must remove the front cover of the  supercharger to perform this installation.

  • Per LPE:

    • Testing at Lingenfelter has shown 680 BHP and 660 lbs ft of torque  with this pulley. The pulley will overdrive the supercharger 19% to  raise boost on a stock engine by 3-4 psi. The stock serpentine belt  is retained but the installation will require ECM programming to  adjust ECM overboost limits [NOTE - IDLER PULLEY DIAMETER CHANGE  REQUIRED - NOT INCLUDED]. 

• Same  diameter pulley as is included in this kit (except the pulley for sale  here is in stainless steel and is a two piece design)

• 19% over-drive compared to the stock pulley

• If all the other pulleys and pulley locations on the engine are stock this  pulley requires you to change the stock 90mm idler to a 100mm idler (not  included)

• Stainless steel pulley for the ultimate in durability and appearance

  • Limited quantities available of the  stainless pulleys
