Applications

A total of around 10 engines were built, but the engine suffered from over-heating at low speeds and required large amounts of maintenance. Around 7 were issued to the Kitai squadron in late 1945 and used on the new Ki-84-N, lacking the supercharger installed on the Ki-94-2 and Ki-87. most are believed to have been scrapped or destroyed after the war along with documentation.
