The Weiand 7582P is a polished 6-71 street supercharger kit, offering a nostalgic styling with modern manufacturing. Engineered for 1955-1986 Small Block Chevrolet engines, this kit is CNC machined for precision and undergoes 100% boost testing to ensure optimal performance. It features matched gear sets for precise rotor alignment, ensuring smooth operation and consistent power delivery. This supercharger kit includes a 34-tooth lower pulley and a 38-tooth upper pulley, providing an 11% underdrive for enhanced streetability. Weiand's 6-71 blower kits are designed to deliver significant increases in horsepower and torque across the RPM range, with some sources suggesting gains of 45-55% more streetable power, or 100-175+ horsepower and torque for heavy-duty applications. The kit comes complete with essential components for installation, including a one-piece aluminum nose drive assembly, upper and lower drive pulleys, an idler pulley with bracket, and a dual V-belt accessory drive. It is designed to produce approximately 10-12 lbs of boost. Weiand's exclusive two-lobe rotors are incorporated for maximum boost at lower RPMs.
