What is the difference between IO-520 and IO-470?
The IO520 and IO470 Rear Alternator engines are referred to as Sandcast Engines. They share the same engine cases, crankshaft, lifters and almost all internal components. IO520 versions simply have a larger cylinder bore than the IO470. 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 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.The Continental IO- 550 AvGas engine offers 280 to 350 horsepower, delivering high performance and reliability on every mission you take.The IO-550-D engine generates 300 horsepower at 2,700 rpm, and has no limitations. 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.The IO-580-B1A is a 315 HP fuel injected, direct drive, six cylinder, horizontally opposed air cooled engine with an automotive type starter.
How much horsepower does the IO-520 have?
The Continental IO-520-A is a 285-horsepower, fuel-injected, air-cooled aircraft engine built for rugged performance in utility and personal aircraft. Continental has a similar system, but with some of the prefix letters different (although I and O mean fuel injected and opposed in their system too). Thus their IO-370 is fuel injected, opposed and 370 cubic inches.
