HOW TWIN SCREW SUPERCHARGERS WORK Twin Screw Superchargers have been known to increase performance and efficiency of engines for decades. But how do they work and what do they do when applied to your motor vehicle? According to, the first Twin Screw Supercharger was patented by Heinrich Krigar in Germany in 1878. Its main purpose was to be used as a compressor for heavy machines. Over some time it was eventually redesigned and was then able to work on gas powered motors. The superchargers’ main mission is to produce more horsepower and torque for its applications. But how do they accomplish this mission? There are three key parts to how twin screw superchargers work. The components of the supercharger, how the supercharger operates on your engine and what the supercharger will produce. There are four main components when dealing with a twin screw supercharger. The first main component that is vital to any twin screw is the rotors. They look like two big screws laying parallel to each other. The rotors rotate counter of each other causing air to be compressed in small air pockets. The two rotors will never come in contact with each other because that would cause excessive wear and would not allow for air to be compressed inside. The next component that plays an important part of the twin screw process is the aluminum outer casing. The main purpose of the case is to protect and enclose the rotors in an air tight container which allows for proper lubrication and air compression. The billet drive assembly is another component of the twin screw. This component is also referred to as the neck because of its shape. The drive assembly is a cylinder like piece that comes out of the front of the supercharger aluminum case. It acts as a connector from the pulley to the rotors. This piece is what allows the rotors to spin. The last
