# Superior Air Parts Vantage

The Superior Air Parts Vantage is a type certified piston aircraft engine developed by Superior Air Parts of Coppell, Texas, United States and based upon the non-certified Superior Air Parts XP-360. The design is officially designated the Superior Air Parts O-360 and IO-360. Vantage is a marketing name.
The company is owned by the Chinese company Superior Aviation Beijing, which is 60% owned by Chairman Cheng Shenzong and 40% owned by Beijing E-Town, an economic development agency of the municipal government of Beijing.

## Development

The Vantage engine is a development of the XP-360 experimental engine that was put through the US Federal Aviation Administration engine type certification process starting in 1996. Certification was based on FAR 33 through amendment 20, effective 13 December 2000, application 17 July 2001 and certification was achieved on 31 March 2004. The initial time between overhauls was set at 1,000 hours, with an aim of expanding that to 2,000 hours.

## Design

The engine is a four-cylinder, horizontally opposed, four-stroke, 361 cu in (5,916 cc) displacement, air-cooled, direct-drive, gasoline engine design. It produces 165 to 180 hp (123 to 134 kW), depending on the model. It is available in carburetor-equipped and fuel injected versions.
