History
The Wright R-3350 twin row radial engine started its development cycle in 1937, and the engine first flew on an airplane in 1941. It was an eighteen cylinder radial engine originally rated at 2200 hp, but later models with fuel injection produced over 3600 hp. Used in the Boeing B-29 during the war, the turbo-compound version developed after the war was used in various types of airliners, including the Lockheed Constellation and the Douglas DC-7. More recently, these engines have powered Reno-type air racers, notably Hawker Sea Furys and Grumman F8F Bearcats.
