It's so easy to gain power with a centrifugal supercharger that it's almost wrong. The Gen II system includes a 3.33-inch blower pulley, which can be changed in a matter of minutes, if not seconds. For our testing purposes we also ordered 3.12- and 2.95-inch blower pulleys (PN 2A031-312 and 2A031-295) and an optional 7.8-inch crank pulley (PN 4MA018-061). View Related Article
