I was doing some research into the Ki-44-III and ran across these specs for the Ha[45]41 NK9A of the Shoki 3 fighter. There seems to be only about a half dozen Ki-44-III made but with this engine's power output it must have been hot. This engine is also referred to as the Homare 10. I am wondering with these numbers why is the Homare 11 of the N1K1-J and Ki-84 is so much less in performance and why the Homare 10 was not used. Of course I suspect these numbers are not accurate. Does anyone have any information on this engine or can shed some light on this.
My info on the Homare 21 has it a 1940 cu. in. 18 cylinder radial with 1970 take-off HP. tapering off to 1000 HP at 22,000 feet. Sorry, no gen on the Homare 10.

Interesting thread, krieghund.
Where did you know Homare 10 for Ha-145?
As long as I know, the army Ha-145 was equivalent to the navy Homare 40s with 2-stage 3-speed supercharger.
Ha-45-41 was an integrated designation for Homare 41.
A while back I got a spreadsheet from the Biglobe website of a guy who had all kinds of aerodynamic materials on it and one was engines of the Japanese navy army. His name was ながもり
His site has been down now for a few years. This is an excerpt of the Ha145 engine.
