IO-390 Type Piston aero-engine Manufacturer Lycoming Engines First run 2002 Major applications Amateur-built aircraft The Lycoming IO-390 engine is a horizontally opposed, four-cylinder aircraft engine, manufactured by Lycoming Engines.[1][2]
There is no carburetted version of the engine, which would have been designated O-390 and therefore the base model is the IO-390.[1][2]

Design and development
The engine was originally conceived in the 1970s as the IO-400-X, but the project was never pursued.[3]
The IO-390 family of engines, which Lycoming refers to as the IO-390-X, produce 200 hp (149 kW) to 210 hp (157 kW). The IO-390 was developed from the similar IO-360 engine, by using cylinders from the IO-580 to increase the O-360's cylinder bore. It features a tuned induction system, roller tappets and Slick Start ignition. The engine has a fuel injection system which meters fuel in proportion to the induction airflow with fuel vaporization taking place at the intake ports. The engine has a displacement of 390 cubic inches (6.39 litres). The cylinders have air-cooled heads.[1][2][3]
The IO-390 was first introduced at AirVenture 2002. It has a factory recommended TBO of 2000 hours and requires a dynafocal engine mount.[2][3]
The IO-390 was initially marketed through Lycoming's custom engine subsidiary, Thunderbolt Engines, prior to the engine's certification and was at that time only available for installation on non-certified aircraft. The IO-390 was certified on 30 March 2009 to FAR 33 effective February 1, 1965, as amended by 33-1 through 33-24.[1][2][3][4]
In January 2009 the base price of the IO-390-EXP version was USD$$32,650.00.[5]
In November 2009 Lycoming announced that they had obtained an FAA Supplemental Type Certificate to replace the originally fitted Lycoming O-360 engines in the Mooney M20E, M20F and M20J with a new or remanufactured IO-390-A3A6 engine.[6]
