The Menasco Pirate series are four-cylinder, air-cooled, in-line, inverted aero-engines, built by the Menasco Motors Company of Burbank, California, for use in light general and sport aircraft during the 1930s and 1940s. [1] The Menasco engines came in both normally aspirated and supercharged forms, with the supercharged models exhibiting superior performance at higher altitudes, with a relatively small increase in dimensions and weight. The supercharged models had the S suffix added to their designation to show supercharging. [2]
