At the end of the war, a turbocharger was developed for them, increasing power to 500 hp. One of them were even captured and tested by the USN.
source?
Also, I do you think we can get better shells for Japanese tanks? Apparently some are missing the improved tungsten rounds

Something that’s curious to me is that the Type 98 Ro-Ke has what looks to me an identical suspension layout of the proposed Type 2 Ke-To suspension layout. However, the Ro-Ke was adopted in 1938, years before the Ke-To would be produced

It is mentioned in both Japanese and English-language materials. Here is an example excerpt from the report of the American naval technical mission:

There are other sources, but I don’t see the point in looking for them additionally
Technically impossible, until the Gaijin abandons its self-invented formulas for armor penetration (distorted formula from AaG), or until it makes an exception for Japanese AP shells, as for example it made an exception for Russian APFSDS which are configured manually by developers for the official reason “their characteristics cannot be displayed by a formula”.
It might seem strange to you that even late Japanese tank shells do not carry armor-piercing caps, while the technology was known to them (in the Navy, they probably created the most advanced, and the most complex in design/production armor-piercing caps in history). The fact is that Japanese armor-piercing shells have complex gradient front surface cementation and hardening, therefore they have a kind of “built-in armor-piercing cap”, what in reality is a technology that fully replaces a separate armor-piercing cap according to the results of ballistic tests, at least until we do not take battleship AP shells, where both technologies should already be applied due “square–cube law”.

Note - the hardness numbers are from an early projectile, but they demonstrate the hardness distribution well.
During the war, Japan was one of the world’s largest producers of tungsten thanks to deposits in Korea and Manchuria; in addition, through a network of front companies, China actively sold tungsten from its southern deposits to Japan. Having fairly decent access to tungsten at that time, in response to the increase in armor protection of enemy tanks, it was decided rather quickly to begin introducing tungsten into the composition of projectiles. This was also facilitated by limiting the growth of the power of guns. Due to the characteristics of the theater of operations, namely huge logistics lines, often extremely rugged terrain with undeveloped infrastructure, etc., the possibilities for increasing the mass of guns were limited. For example, the project of a 57 mm (anti-)tank gun, which was supposed to replace 47 mm (anti-)tank guns, was buried because, according to test results, operators found it difficult to operate it manually in difficult conditions due to the increased mass.

By the way, for the reasons described above, they were quite attracted to APCR shells, but the APCR shells made using German technology turned out to be not much more penetrating than the later Japanese tungsten-chromium AP shells, even when shooting at vertical armor plates, and APCR did not go into mass production. As an alternative, German conical guns were studied (in addition, Japanese independent research on conical guns was going on in parallel), but ultimately they were also not considered promising, compared to the recoilless rifles.
When Japanese tank shells in production switched to from “regular” projectile steel to tungsten-chromium steel, the impact strength and hardness of the projectile increases by a quarter compared to conventional projectiles, which cannot be reflected by the current formula.
Spoiler
Note - Japanese shells contained 1% tungsten, as in the graphic materials provided. For projectiles, the hardness numbers (on the surface) would be even much higher due to carburization, the presence of additional alloying impurities in the composition and “hard” face hardening, but this will give a general understanding of the effect of introducing tungsten into the composition of chromium steel.
Pay attention to the improvement in the structure: how much the metal crystals have decreased, the structure has homogenized, and solid-phase precipitation has decreased when tungsten is introduced into the composition of the alloy:
In other words, neither the gradient hardness nor the unique chemical composition of Japanese projectile steel can in principle be reflected by such a primitive armor penetration formula without introducing any external coefficients into it. As far as I know, at least some developers are aware of the problem thanks to some assistant proactive guys, but if we translate developers words from “official”, they not really interested in messing around, this is not considered something important for the game. The funny thing is that the original AaG formula, taken as the basis for the gaijin formula, was closer to the reliable armor penetration of Japanese shells, everything was radically distorted by the gaijin’s personal “improvement of the formula.”

is that the Universal hull with 1000hp engine? i heard it got beef engines compared to the type 89’s
Common Tracked Hull is powered by the same Mitsubishi 4VA engine (570HP) as the Type 16

is this the type 16 engine?
This is the engine used in the common tracked vehicle.
Type 16 engine.
As being said, probably same enigne.

yeah it is the Type 16 engine then
Testing out the Type 4 new 500HP engine on the devserver.
Whether it’s an improvement or stays the same, I’ll let you be the judge.
Had to make video look crap because of the 4mb limit.

Can accelerate a bit faster it seems though you probably need to make a comparison of both clips on 1 screen to see it more clear. Good slight improvement.

looks like it can’t realize all of its power because of gear ratios
So the transmission data is needed…

I’ve updated the thread to reflect the recent developments, incorporating the discussion on the Thai ground forces in light of the Royal Thai Air Force F-5E FCU’s inclusion in the Japanese aviation tech tree as a squadron vehicle. With this addition, it’s reasonable to anticipate the emergence of Thailand as a sub-tree in the future.

Uhm, there is already a thread for Thailand :o

It seems like everything is mixed up and prioritized solely on Thailand, but this thread from now on primarily focuses on the ground forces of both nations. This way, everyone can discuss IJA, JGSDF and RTA vehicles on the same page without the need to switch back and forth.
Although this thread will still mainly focus on the Japan as it always has.
Ultimately, it’s up to the people to decide which thread they want to discuss. I’m simply not restricting anyone from bringing in Thai ground forces into this thread. That’s all. :)
