Powerplant

Powerplant

The benefits and increased performance offered by either the IO-520-D engine or the IO-550-D engine are impressive, with a few differences.IO-520-D

The IO-520-D engine generates 300 horsepower at an RPM of 2850, which is allowed for 5 minute intervals. On take off, at full throttle, 300 horsepower are available for five minutes, then a power change is made to bring the engine back to 285 horsepower (maximum continuous horsepower).

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.

Your engine will be equipped with a new starter, Bendix 1200 series magentos, harness and plugs, heavy duty non congealing oil cooler, high capacity oil pump, VAR crankshaft, Heavy crankcase (7th Stud) and integral oil filter.

Installation

Installation

Installation of both engines are exactly the same, the only difference being the engine that is installed. The 300 horse installation involves the addition of fuel injection to the Cessna 182, which requires a modification to the stock gravity fed fuel system. The system installed is similar to the one used in the Cessna 185, Cessna 206 and Cessna 210. Modifications in the fuel compartment are minimal, involving a change to the engine mount, clearance gained at the firewall, and the remainder of the fuel injection system installed. The only noticeable external change is the addition of the 3 blade propeller and polished spinner.

Our Air Plains 300 horsepower engine conversion design and installation have been developed from our experience in modifying and maintaining other Cessna aircraft at our facilities for more than a quarter of a century. Whether installed here at our facility (approximately 15 working days), or shipped to your local shop for installation (approximately 150 to 180 man hours of labor). Your Air Plains engine conversion has been developed to be delivered as a complete kit. Our standardized kit, installation instructions, blueprints, and continued airworthiness manual, safeguards the procedures and standards for installation and maintenance of your new conversion... no matter where you choose to have your conversion installed.
