How much horsepower does a Continental IO 550 have?
The Continental IO- 550 AvGas engine offers 280 to 350 horsepower, delivering high performance and reliability on every mission you take. Consider a Continental IO-550 engine rated at 300 hp. If the fuel system is set up properly per Continental Service Bulletin SID97-3F, fuel flow at maximum takeoff power is about 26.
What is the IO-550 engine upgrade?
The Wipline IO-550 upgrade is rated at 300 Horsepower, like the standard 520, but is rated at a higher torque, giving you 8-10% better performance, an additional 150 to 175 points of thrust for seaplanes, and quieter ride. 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.
