  Weiand 8-71 Supercharger on Hemi  

Want maximum power from Weiand out of your Big Block or Small Block Chevrolet? The 8-71 series is for the enthusiast with a passion for power and you won't find a more aggressive look. They utilize reconditioned GM three lobe rotors for peak performance under demanding high RPM conditions. Engineered to produce 10-12 lbs of boost on small blocks and 5-7 lbs on big blocks (depending on application and engine efficiency) -these are for the hard core enthusiast!

All 8-71 kits come with the extra tough 8mm (two piece billet snout) belt configurations for maximum strength. Satin or polished finishes are available to match the “hard-core” or “show and go” look you’re after.

All superchargers are built in Weiand’s state-ofthe- art manufacturing cell and each is 100% boost tested to help you squeeze the maximum power and efficiency out of your supercharger.
