The supercharger is typically driven directly from the engine's crankshaft via a belt or gear drive. Each rotor is radially symmetrical, but laterally asymmetric. The Eaton supercharger increases torque across the entire operating range without compromising drivability or emissions. Roots Because of their ability to produce an abundance of boost (HP and torque) at virtually any engine rpm, the Twin Screw and Roots type are the two most logical choices for supercharging. A roots style is the same to a point, but has a major flaw in that at the top of the rpm band it looses a great deal of its boost due to its design. All the superchargers mean to produce more power in an internal combustion engine. the Pro charger is centrifugal, it builds boost depending on what RPM you are on. The twin screw supercharger at first glance appears to look similar to a roots supercharger both inside and out. Superchargers typically will offer better throttle response, and can offer better low-end torque, however they ultimately are less efficient than turbochargers. Superchargers generally fall into one of four categories: roots and twin screw\ lobe types, or the centrifugal-type spun by either engine power or an electric motor. The salesman forgot to tell you that your 6 psi kit only makes the “advertised” 6 psi at 6000 rpm. The Roots supercharger is the oldest design.
