Big Block Mopar 440 Carbureted Paxton Centrifugal Supercharger

Paxton's line up of carbureted superchargers will allow you to add boost to your big block Mopar V8s. With a NOVI-1500 supercharger will produce 5 to 6 PSI of boost at 6,000 RPM. Depending on your HEMI engine, you should see gains of 30-75%. Includes the carburetor enclosure for fuel delivery. The supplied crank pulley is designed to work with the OEM Dodge twin V-groove accessory crank pulley. For correct belt alignment, the proper accessory drive crank pulley must be used. This universal system requires the installer to source a high volume fuel pump and a properly jetted 4150 style carburetor unit (with mechanical secondaries). Vehicle throttle cable/arm modifications may be required. A replacement hood or hood modifications may be required depending upon the type of intake manifold and carburetor enclosure / bonnet installed on the engine.
