According to Australians and Americans, the engine used in Ha-Go and few other Japanese tanks could do 200-250 bhp at 2000rpm. The usual rating used by Japanese was 120hp at 1400rpm. Would that extra capacity make sense in game?
Similarly Chi-Ha’s engine was reported to be capable of 365hp at 2000rpm. I’m still not certain what the usual engine rpm was. It’s often said to be 2000rpm, though one American document mentions 1500rpm and a single Japanese document gives 1700rpm.
I thought this number seemed too high, but the Chi-Ha’s engine is very big displacement, almost 22L. That’s around the same size as the Tiger 1’s engine which makes 650hp (though it uses gasoline and not diesel, and is likely much more advanced).
So it’s plausible that it made that much power, though I have my doubts it went as high as 365hp. 200-250hp feels more realistic.
I have already submitted the error report.

I’ve got no clue, all I know is that it’s 13.7 without it and that’s just sad.
you think that gaijin will fix the problems that they create? 😂
It had no HMS at all in reality.
What it really needs is AMRAAM removed, countermeasures fixed to 120 (instead of 45) and the BR lowered to 13.0
If you want an error report to be approved faster, there’s an unreliable method getting a large number of players to click I have the same issue. I posted on Facebook asking for support, and everyone was very enthusiastic except for one time. I reported that the rear of the antelope was missing a warning label, but the submitted error report was not accepted so sad.
While looking for other stuff, I also tried to find mentions about what sights those Japanese 37mm tank guns used. After all they had the muzzle velocity for some range and Japanese were happy mounting 1.5x, 2.5x and even 4x sights on 7.7mm machine guns. Unfortunately this mention about Ha-Go’s gun sight is the only one I have found so far. 8x sights with such gun would definitely be interesting. I’d imagine the sights could be adjusted for less or some other option. Another quite high magnification sight were 7x sights mounted on 47mm Type 1 Anti-Tank gun.
After researching the Ho-Ro’s sights, I would like to share the following details.
The Type 4 Ho-Ro was equipped with two sights:
The tank commander’s sight was used for engaging distant targets.
Specifications:
Type 97 5.7 cm Tank Gun Sight
Type 38 15 cm Howitzer Sight

Thank you from your dedication!
You dug really deep for it. I think you could could copy that straight into a bugreport.
So the commander’s sight was mounted on the right side of the gun? Difficult to say how they would model that.
Depression of -20 degrees? O_O
It is nice work.
But could I ask you, wasn’t there the possibility for commander to fire separately? Tbh I can’t say is it possible to unite this 2 optics as 2-4x but if commander could aim and fire gun by itself, the double cannon control mechanic can be given for this gun
Judging by the title, he did, in fact, find the Chi-Ri to be a joy to play again.
Common Spookston W.
It’s a very nice buff for sure, just wish they’d let us carry zero ammo for the nigh-useless 37mm.
Or, as Spookston mentioned in the video, HE shells would be useful.
Since the aiming drive mechanism handwheel is only on the left side of the gun, I don’t think the tank commander alone can aim and fire the gun.
I’ve posted the current known details about the tank sights in the bug report.
The Ho-I had the same 4x magnification Type 1 telescopic sight Ko as the Chi-Ha Kai, Chi-He, and Chi-Nu.

The Ka-Mi had a 4x magnification Type 100 telescopic sight. I will write a bug report about the Ke-Ni later as well.

Also true, however I find the 37mm ammo rack to be more of a risk regardless.
If the earlier tank guns came with 2x magnification sights, then that’s practically all IJA tank gun sights reported. Only ones left are those 120mm naval guns on Chi-Has, which might be too difficult to find.
I just hope they will be fixed faster than the sights on long 75mm guns. Chi-Nu’s sights were fixed in couple of months, but these have already taken a year…

I forgot about the gun sight on the American tanks used by JGSDF. Their M4A3E8s might have had 4-8x gun sights. These became a standard in American use after the war, when they were selling away all the none M4A3 tanks. I don’t know if the US M4A3 76mm is supposed to be a war time modification or post-war, but the Japanese one is definitely post-war. Even JGSDF M24 might have had these.
Where could we possibly find JGSDF Chaffee and Sherman manuals?
I’m pretty sure it’s post war because of the lack of smoke grenade launchers and iirc slower turret traverse than other 76 Shermans
