  • Description


    The internal parts have been redesigned to outperform the original period supercharger. The shafts are 4140 chrome-molly steel and run all the way through the rotors. The 8620 carburized gears have switched positions with the bearings, so the bearings now carry the moment load ahead of the gears. The gears have more teeth, an improved pressure angle and a pitch diameter that meshes precisely. This results in less gear friction, reduced noise and increased reliability.

    The kit includes the supercharger assembly, carburetor mounting flange, induction flange, drive pulley, two v-belts, air and main carburetor jets, modified throttle and choke linkages, gaskets, a custom 13mm/14mm “s” wrench, all hardware and an installation manual. If your vintage volkswagen 25/36 hp engine is from 1949-1954, this kit is 100% complete and ready to install today….No modifications are necessary. If your engine is from 1955-1960, then only one tiny modification is required….You may have to trim the generator pulley in order to clear the the supercharger.

    The speedwell supercharger is absolutely period correct! This masterpiece was designed, cast, machined, heat treated, assembled and tested all completely in san jose, california. You are getting a quality american product that was hand built to perfection.
