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. 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. ** Requires small cap distributor to clear supercharger housing. Requires short water pump and accessory brackets for installation. Works with one or two accessory belts. It is highly recommended to use a steel SFI approved blower balancer and a double keyed crank. With the pulleys supplied this kit will make 11-12 Psi boost on a 350 Engine. The Lowest boost you can make with the pulleys we offer is 9 Psi
The Weiand Company was founded by Phil Weiand as a performance parts warehouse in the 1930s and sold a variety of speed parts. The first Weiand product, the "High Weiand" manifold was manufactured and marketed in 1937. It was the first aluminum intake on the market. In 1949 Weiand introduced a series of "tri-power" and four 2-barrel manifolds and immediately after WWII Weiand debuted a line of aluminum cylinder heads for flathead fits Ford engines. The famous "Drag Star" line of "log" manifolds for Hemi engines was introduced in 1952 and in 1957 Weiand developed complete blower drives for the fits GMC 6-71 supercharger. Other feats first dual plane, "Colt" 180 degree intake 1965, and in 1968 came the "Hi-Ram Manifold" with its patented D-port technology. Next "X-terminator" single plane manifold series in 1972 and Weiands high performance aluminum water pumps the following year. "X-CELerator", a series of performance single plane intakes was developed in 1974. "Team G" series of 360 racing manifolds were introduced in 1978. A year later "Action" series of high performance replacement manifolds debuted. Weiand became the first OE supplier of superchargers to Mercury Performance Marine in 1990, and over the next three years the "Stealth" series of high performance dual plane manifolds was designed, the "Pro-Street" supercharger was certified "emissions legal" by CARB and Weiand received the industry's first "E.O." for an intake manifold. Then the 8-71 supercharger for SBC and BBC in 1996 and the first aluminum LS-1 intake manifold in 2002. In 2005 Weiand began designing manifolds on Computational Fluid Dynamics software to deliver perfectly designed runner lengths for maximum air/fuel delivery on its newest intakes the Warrior line. To make more power you have to get more air into your engine. Look to Weiand as your power source, or partner with products from other Holley companies, to give you even more power!
