6-71 Street Polished Supercharger Kit (7581P) by Weiand®. Weiand’s 6-71 kits are the ultimate statement of power and looks. Pull into the local cruise-in or drag strip 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.
