Weiand 8-71 Street Superchargers

More than 40 Years in the Supercharger Business

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 (two piece billet snout) 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.
