How much horsepower does the IO-520 engine have?
The IO-520 series engines normally produce 285 to 310 horsepower (210 to 230 kW) and are used in numerous aircraft such as certain models of the Bellanca Viking 300 and Super Viking, the Beech Bonanza and Baron, and Cessna 185- 206-, 210-, 310-, and 400-series aircraft. The IO-520 remained in production in 2019.

This engine produces between 230 and 350 hp; it is air-cooled and it has six cylinders.Producing between 230 and 350 horsepower (170 and 260 kW) these engines are installed in a large variety of aircraft. The main competitors are the Continental IO-520 and IO-550 series.The Continental IO-520-A is a 285-horsepower, fuel-injected, air-cooled aircraft engine built for rugged performance in utility and personal aircraft.
What is the difference between IO-520 and 550?
The basic difference between the IO-520 engine and the IO-550 engine is the stroke of the piston within the cylinder, the 550 being longer, thus creating more cubic inches, and 300 sustainable horsepower through increased torque. In properly built form, a Boss 520 can produce well over 800 horsepower and more than 700 lb-ft of torque without forced induction. Advanced aluminum cylinder heads, high-flow intake systems, and forged rotating assemblies allow it to operate reliably at high RPM.
