    Weiand superchargers can be found in all aspects of racing, from tractor pulls to the quarter mile. When you pull into your local cruise-in or dragstrip with one of these 8-71 superchargers sticking through the hood you are sure to be noticed. Producing 200-300 more horsepower, the 8-71 supercharger is for the hard core enthusiast!

    All 8-71 kits come with the extra tough 8mm belt configuration for maximum strength and durability.

    Installation Notes:
  • 8-71 Superchargers are perfectly suited for modified engines with 7.5:1 to 8:1 compression ratios. May require race gas unless pulley ratios are altered to reduce effective compression ratio below 12:1 (See 8-71 Supercharger Pulleys)
  • Kits are designed for stamped steel V-belt accessories. The use of billet pulleys may require custom machine work and/or spacers.
  • Must use short water pumps with maximum 2 "V" pulley.
  • Weiand highly recommendeds the use of a double keyed crankshaft and double keyed, steel, SFI approved balancer.

    Note: Will not clear GM HEI distributor. Engine not included.
