If you’re interested in building your own supercharger packages for kit to resale to the general public, there is no better supercharger than a Whipple Twin Screw Compressor. OEM manufactures utilize positive displacement superchargers due to their incredible throttle response and drive-ability of a big cubic inch motor. When building a system for the consumers, you must provide a very broad power band with a high peak horsepower level, only the screw compressor can give you this. This is due to the high adiabatic (up to 80%) and volumetric efficiency levels (up to 99.9%). The Whipple screw compressor is the latest generation, durable and dependable performance-enhancing item ever designed for either low boost or high boost levels. Available in a complete unit or a “rotor assembly” for builders own housings.
