This website has a chart which contains information about a Japanese Mitsubishi aircraft engine whose "Army" number was the Ha-4.


Mitsubishi Ha-4 weight: 715kg; displacement 41 liters or 2501 cu in; take off horse power 1100hp@2400rpm; max h.p. 1100hp @ 9842 ft @ 2300rpm.

This engine may have been a development of the Mitsubishi Ha-2 engine used in the Ki-1 bomber of the early 1930s. Does anyone have any other info?
