The Magnuson M.O.A.B. (Mother of all blowers) blends the iconic style of traditional Roots blower case first popularized by hot-rodders in the 1940s with advanced TVS3100 rotor technology. Unlike older blowers—plagued by poor idle quality, aggressive underdrive ratios, and low boost to mask their inefficiencies—the M.O.A.B. features high-efficiency 3.1 Liter rotors with a full 140-degree twist, delivering significantly greater horsepower, torque, and instant throttle response.

Paired with Magnuson’s vacuum-operated bypass valve, the M.O.A.B. generates substantially more power with dramatically improved efficiency, reduced parasitic drag, and lower operating temperatures. Direct bolt-on compatibility with standard Roots manifolds and accessories ensures easy upgrades for your street rod, LS restomod, or classic muscle project. This supercharger will work in both fuel injected or carbureted applications.

Note: Does not include a manifold but will bolt on to any 6-71 or 8-71 blower manifold! We sell Whipple BBC blower manifolds leave a note if interested! If you'd like the blower in a polished finish it is available for $300.

*Notice, leave a note about what size snout you would like (3.90", 5.15", 5.90", 6.90", 7.90") *7.90" can be made into a 8.40" when using a 1/2" spacer
