Unfortunately, we have no flight performance data. Maybe it might be easier to estimate for a bomber. They literally did it for the J6K
Did he said you said this is everyone’s opinion?
I forgot Ki-91 was listed in these. They also confirm the quad turret.
engine data from: Test engines, specifications and performance. Report No. 16i(7)
Ha-214Ru
2500hp take-off with 2600rpm and +600mmHg
2300hp 1st stage at 2000m with 2400rpm and +400mmHg
2310hp 2nd stage at 7600m with 2400rpm and +400mmHg
It has bit different rpm and boost compared to other engines of it’s family.

The reason why the Smithsonian says “Ha-42-41” is the engine of Ki-91 is that they mixed up which engine theirs is. They titled the engine in their inventory “Ha 42 Model 41 Ru (Ha 214 Ru)”, which doesn’t exist.
There is Ha-42-41 and Ha-42-21 (Ha-214 Ru). The Ha-42-41 was just a prototype version of the 31 testing a two-speed reduction gear.
Ki-91 was to use Ha-214 Ru, and later Ha-50 (3000hp) if it was developed.

Thanks for the information, so I can throw the Ha42-41 engine into oblivion. Thank you very much (Mr. Biden) for your help :D
As an italian and japanese main this situation reminds me of the Piaggio P.133. It was like 90% complete before it got bombed into oblivion. The “fun” fact tho is that there seems to be much more documentation on the Ki-91 than on the P.133 which we don’t accurately know what it could’ve looked like (contrary to the Ki-91). Anyway it’s a cool bomber (even tho my fav remains the G8N1) +1

As a Japanese, I would sacrifice my soul for this

we know how it was made (many projects and render are avaible)
Btw +1, it could be an interesting bomber for japan

yes, a payload of 8,000 kg is the maximum payload that the Ki-91 can take with it

japan does need a heavier bomber as it can’t really complete against late war allied bomber. this aircraft would fit well this and the g10 bomber

This along with the G10 bomber would be awesome for Japan, the G8 is nice but compared to planes like the B-29, Tu-4, Shackleton, and He 177 it just doesn’t feel good enough as a end of the line prop bomber

Honestly this gets my +1 near immediately
I am usually against paper planes, but Japan really needs some additions to it’s tech tree and we have a mock-up built + engines + guns already existing, so a performance estimation of the plane’s flight performance should not be a big issue.
see im all for paper planes, but i feel this is required same with the g10n bomber to give japan a comparable high rank bomber
