What Are the Specifications of an M90 Supercharger?

The Eaton M90 supercharger is a positive-displacement, roots-type blower that displaces 90 cubic-feet per minute of air per stroke. It has an rpm limit of 12,000, where it produces about 550 CFM of air at 10 psi of boost pressure while increasing the temperature of the air by 200 degrees Fahrenheit. At those speeds, the supercharger requires about 50 hp from the engine.
