The IO-520 series engines normally produce 285 to 310 horsepower (213 to 231 kW) and are used in numerous aircraft such as certain models of the
The turbocharged GTSIO-520's most common applications are the twin-engine
421
, where it is rated at 375 hp (280 kW). The 'G' prefix indicated the incorporation of propeller reduction gearing.
