71-Series Blowers:

When pioneers like Gene Mooneyham first began adapting GMC 71-series blowers to racing applications it was a relatively easy task to decide what size to use: nearly everyone chose a 6-71 blower. This was mainly due to the fact that the old iron-block engines used throughout the early days of racing couldn't handle too much combustion
pressure without losing cylinder walls.
     With the advent of the aftermarket aluminum block racing engines (equipped with replaceable cylinder sleeves), engine builders quickly discovered that they could use more boost, and the 8-71 became popular. The trend to larger displacement superchargers continued with 10-71, 12-71, 14-71, and even 16-71 size blowers being used.
     Of course, size alone is not the sole criteria for determining which blower is best suited for any particular application. There are other factors to consider, such as rotor speed, clearances, and other internal modifications. Is a "tight" smaller blower better than a "loose" larger one? Or is it the other way around?
     Because of these and other variables (such as engine displacement and compression, type of fuel burned, fuel system, application, etc.) it is recommended that you contact Mooneyham directly to determine which model blower and type of setup is best suited for your particular combination. Whatever you need, Mooneyham has it!

Reconditioned Blowers

In addition to brand new competition models, Mooneyham also makes a wide variety of blowers for nostalgia and marine use, including reconditioned blowers of all sizes. Please call for details on availability and prices.

Aluminum or Magnesium... The Choice is Yours

There are advantages and disadvantages to both aluminum or magnesium blowers. The most obvious difference is the fact that a mag case is approximately 35% lighter than a comparable aluminum case. And for the racer whose objective is to field the absolute lightest possible vehicle, mag is the answer. However, experience has shown that the metallurgical properties of aluminum cases are such that they are less affected by heat and accordingly provide
better long term consistency and reliability.

Manifold Stud Kit

Mooneyham Manifolds

Following many years of extensive research and development, Mooneyham has created the "ultimate" blower manifold for the big block Chevrolet.
