The name Mooneyham is synonymous with competition superchargers...and for good reason. Gene Moneyham was one of the first to recognize the merits of adapting the GMC 71-series blower to drag racing, back in the late 1950's and spent over twenty-five years building blowers for competitors. 

As a testimony to the effectiveness of Mooneyham's blowers, one need only look at the list of racers and engine builders who use them. Moreover, because Mooneyham strongly feels that satisfied customers are the best form of advertisement. You are advised to ask any racer whose engine is equipped with a Mooneyham blower how they like the units performance and reliability.... as well as the service they received.  You can't get a better qualified source of information than the man who buys and uses the product in question.
