What is the Eaton M122 Supercharger?

The Eaton M122 supercharger is a type of positive displacement supercharger, meaning it forces more air into the engine than it could draw naturally. This increased air intake leads to more efficient combustion and a significant boost in horsepower and torque. Specifically, the M122 is known for its roots-type design, which provides almost instantaneous boost across the RPM range. This makes it incredibly responsive and ideal for applications where quick acceleration is desired.

Originally designed and manufactured by Eaton Corporation, the M122 has been used in various high-performance vehicles, most notably in models from Ford and, of course, Cadillac. Its robust design and reliability have made it a favorite among enthusiasts and tuners alike. The M122 is particularly well-suited for Cadillac engines due to its size and performance characteristics. It can be integrated into a variety of Cadillac models with the right modifications and tuning.

The supercharger's design includes two rotors that spin to compress air. As the rotors turn, air is drawn into the supercharger and squeezed, increasing its pressure. This high-pressure air is then forced into the engine's intake manifold, providing a denser charge than the engine could achieve on its own. The result is a more powerful explosion in each cylinder, leading to increased horsepower and torque. The M122's efficiency in delivering this boost is one of the reasons why it’s so popular for performance upgrades.

One of the standout features of the Eaton M122 supercharger is its ability to deliver consistent performance across a wide range of engine speeds.
