Got a HEMI? Weiand has nostalgic supercharger kits for early Chrysler Hemi's (331, 354 or 392). Hemi kits have the traditional 1/2" pitch drive and early one piece snout.

Supercharger Features:

  • Roots-type two-lobe helical rotor eliminates flex
  • Rotor setup closes tolerances for maximum boost efficiency
  • Equal distribution of fuel/air mixture optimizes HP gains
  • Mounts with standard distributor setup
  • Heavy-duty bearing plates eliminate cracking
  • Rear plates use premium sealed ball bearings
  • Front bearings lubricated by oil bath
  • Front rotor shaft seals are double-lipped with PTFE
  • Kits are designed to produce 10-12 lbs of boost on small blocks and 5-7 lbs of boost on big blocks but are a simple pulley change away from pump gas or hard core racing.

    6-71 Street Supercharger Kits Include:
  • Polished or Satin 6-71 Supercharger with gears and bearing plates
  • Supercharger Intake Manifold
  • 2-4V Carburetor Adapter
  • Supercharger to Manifold Gasket
  • Carburetor Adapter to Supercharger Gasket
