In the first part of this article, the principles and benefits of supercharging an air-cooled V-twin were explored along with a description of the major aspects of the ProCharger system, but we kept our hands clean with a classroom approach. This article gets its metaphorical hands dirty by delving into a grease-up-to-its-elbows installation of the ProCharger system and reveals the nitty-gritty real-world power produced by bolting it onto a practically stock bike. While the installation of the system is straightforward and relatively simple, there are many steps involved and important details that if missed, might be cause for disaster if not handled properly. A good tech could have one installed in a day (without photographer interference), but a garage builder should pencil in a weekend and not rush it.
There are many shops that have the skills to bolt one of these superchargers to a bike, but there are few that can prove they’ve done it correctly. Proving that a performance modification yielded a power gain requires a dynamometer, and the shops that are serious about performance have invested in one. It’s usually obvious which ones are serious because their shops have race bikes stored in the service area, photographs of race vehicles on the walls, and a curious bike-sized box with huge conduit tubes sticking out of it. Huntington Beach Hogs and Choppers (HBHC), of Huntington Beach, California, is one of a small number of shops in our area that have the ability, a modern dyno room, and a history of racing, which made them the perfect candidates to provide an example of a professional installation and prove the exciting results with a certified graph of the gains. Plus, HBHC had a test mule desperately in need of some pick-me-up in the form of an ’11 Twin Cam 96ci Dyna with a 2-into-1 exhaust pipe and a 100 percent stock motor. They had ProCharger’s kit installed in about five hours (with photographer interference) with an additional hour on the dyno.
