SUPERCHARGING FOR BIG POWER

Building an engine that produces more horsepower than its stock configuration can be done in many ways. However, supercharging has proven to be one of the best ways to make the most horsepower over stock. Superchargers are air pumps that force a “super” charge of air into an engine, which in turn allows the engine to make more power. A Roots supercharger or blower is a sealed case with two rotors inside. It is driven through the crankshaft by belts and pulleys, causing the spinning rotors to force compressed air into an engine.

Choosing The Right Cam

Cam-speak is a language all its own. Well, maybe not from a linguistic point of view, but it is a specialized dialect of car-guy talk. Although spoken by a good portion of enthusiasts, Cam-speak is really fully understood by only a handful of those same enthusiasts, as it is a very specialized, nuanced dialect. Those who do not speak the lingo can instantly be singled out. Those who are fluent in cam-speak are listened to intently, even when those listening do not fully comprehend whatʼs being said and how to apply it to their particular applications. Few within our ranks are particularly fluent in this highly specialized jargon.
