Description

The TorqStorm Big Block MOPAR RB 440-Single Supercharger PLUS KIT is a high-performance upgrade designed to mount on the passenger side of 383/400 Big Block Mopar RB engines. This comprehensive kit includes the TorqStorm® Supercharger, couplers, clamps, a blow-off valve (BOV) and tube, an air filter, and a carburetor hat. It also comes with all the necessary brackets, pulleys, and hardware required for a complete installation of the supercharger system onto your engine. The "PLUS Kit" variant further enhances the package by incorporating a Sanden SD-7 AC compressor, a Type 2 power steering pump, and a Powermaster 165 amp alternator, providing a more integrated accessory solution. Additional components are necessary for a fully functional installation, including a blow-through carburetor or a proper throttle body injection system, an electronic fuel pump capable of maintaining the correct fuel pressure, and a 1:1 boost-referenced fuel pressure regulator. For optimal performance and engine protection under boost, an ignition system that can pull timing, such as the MSD BTM 6462, is highly recommended, and the use of premium fuel is mandatory. Intercooling is suggested for all non-carbureted applications, and a bung is provided for water-meth injection.
