A true blast form the past. These highly sought after superchargers have been unavailable for years. Weiand is proud to reintroduce them. The case of the 6-71 and 8-71 superchargers have been redesigned for a nostalgic look that will look at home on a cacklefest dragster as well as a new high end build.

HORSEPOWER! - Weiand's 6-71 kits are the ultimate statement of power and looks. Pull into the local cruise-in or dragstrip with one of these sticking through the hood and you will get noticed. They're not for the meek however - these supercharger kits are designed to generate 50%+ more horsepower and torque across the rpm range!

Weiand's 6-71 blower kits are equipped with exclusive two lobe rotors for maximum boost at lower RPMs. All feature a new case, end-plates, manifold and snout. Billet belt tensioner components and V-belt pulleys round out the package to give you everything necessary for installation. Kits are engineered 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.

The 7587 kits fearture he extra tough 8mm (two piece billet snout) belt systems for durability while on the street or water.

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