Why do all japanese props suffer from comically bad overheating?

it doesn’t matter if it’s a j2m with a mitsubishi engine, or a ki83 with a nakajima engine, or anything else. Japanese props simply overheat, and boy do they overheat, even earlier than the f8f and the i225. For aircraft that make the most of their engines to literally survive this is a massive detriment.

So find a source that said that they don’t overheat like they do ig and submit it, otherwise stay coping and learn to use mec.

Wonderful, mantis has returned.
I can not wait for more cope spam!

there are sources for the corsair flatspinning at slow speed and gaijin took 10 years to implement it. Meanwhile japan’s “historical” overheating has been since thermodynamics update.

Cool now find sources for your overheating problem then we’ll talk.

J2M is super easy to manage.
Try preventing Bf 109 from overheating. It’s essentialy RPM micromanagement. Say goodbye to AFK climbing.

Ki-83 is a bit more tricky indeed, but still manageable.

Edit: The worst overheating offender for me is Ta-152H. Only the oil overheats, it requires you to run the engine 100-150HP below maximum, you have to constantly adjust the RPM and the right RPM to not overheat varies greatly depending on alt.
Meanwhile water stays relatively cool.
So basically you have to keep the radiator open above 50% lose a ton of performance, and all thx to oil overheating.
It’s a lot, and I mean a lot easier to manage planes where:

  • oil radiator can be controlled (because oil temp is greatly affected by that, while planes like Ta, that have 1.set of radiator flaps, changing radiator settings barely make any difference)
  • prop pitch controls engine RPM directly.

Time for you to use MEC :)

yeah j2m and radial engine props of japan overall are easy to manage, but the heating is still there

ki83 won’t overheat om 90 pitch and 30 rads until you start dogfighting where even 100 radiators and 87 pitch your engines still die.

Edit: The worst overheating offender for me is Ta-152H. Only the oil overheats, it requires you to run the engine 100-150HP below maximum, you have to constantly adjust the RPM and the right RPM to not overheat varies greatly depending on alt.

I never use MEC with Junkers engines, they scare me because they still over-rev past 65 pitch but they don’t airbrake like germans, and throttling down doesn’t prevent over revving.

I always use mec on japanese, they’re slow already and having the radiators open and prop pitch below 95 makes them even slower. In fact i always use mec except on 190s beyond opening the radiators.

You see, it’s not that bad. J2M with slightly lower prop.pitch barely loses engine power, and you can go even lower with radiators. It’s not fast at 5.0, but 5m0 Fw 190 will mot get guns on target if you dodge right. So it’s pain both ways.

Anyway, Ki-83 is kind of struggle bus post 30mm nerf.

I dont have access to my PC for the docs, but the US survey of the late war japanese props did show

10 years? That’s been happening since at least 2019…
Overheating doesn’t happen on MEC.

Got any proof or source that says they shouldn´t overheat?

…make sense to limit your criticism to JP planes only.

Imho you might consider to read this thread:

It boils down that gaijin uses wrong settings for AEC and has implemented a kind of engine degradation which limits the timespan you can use 100% and 110% (WEP).

The degradation part reduces critical oil/water temperatures over time. Classic example is the 190 F-8: Longer games leads to flashing red 83°celsius oil temperatures, whilst 83° celsius is “white” at the beginning of a match. To be fair: WEP usage was limited (A-models ~3 min), same as flying with 100% engine power.

I do agree on the fact that Germany suffers a lot with their 109s (except G-10s for the first 5 minutes), the main issue is that the usage of prop pitch adjustments for 109s requires a lot of experience to avoid over-rev the engine.

Imho gaijin is unable to simulate the EVG device correctly:

Germany air needs a premium 109 - #86 by Uncle_J_Wick

Especially if you fly the same engines outside a 109 - you can ez use pp & rads to create an “infinite” WEP setting (= WEPping the whole match) without overheating or killing your engine due to too high revs…

Are you opening your radiators?

Ah yes, Mantis’s famous whataboutism!

It’s the same with all the 190s now. No adjustable oil cooler, even at 100% throttle (especially in the Doras) it’ll overheat and you have to go down to 90% for its temp to go down.

Even at WEP and 100% PP, with 30% rads the J2M will stay cool.

I like how you mention the J2M as supposedly running hot (which it doesn’t) but don’t mention the Ki-44-II or Ki-61-Is which REQUIRE prop pitch to be lowered for any meaningful use of WEP, as even 100% rads won’t keep them cool.

It is, but with Ta, back in the day, you often had to kill entire enemy team. And that required some longevity. Fw 190s on moderate maps do quite well, and you have more and better reasons to throttle down later in the match, as they have way better climb and speed than Ta-152H for their respective BR.

Anyway, I wish the Fw 190 oil radiators got buffed a bit, because it’s simply ridiculous how much performance has to be sacrificed for the engine to not run orange 2 minutes into the game.
