Don't they have no MW-50 at least in some fighter slots in Wolf Pack US, as a game balancing move? (I forget offhand if the Dora does it but lately the Kurfurst seems to make the MW-50 boost sound even if there is none, which is confusing. I'll check later and see if the Dora is doing the same. If so that might be making it non-obvious that there's no MW-50 in it.)

I see their Briefing text says
 

Quote

"A few of the  bf109s do not have MW50. Look at the aircraft name in the role selection to determine which planes have MW50 and which planes do not have MW50. There are a few cold start aircraft as well."

None of the Dora slots mention MW50 so maybe this isn't the issue. I'll try to go for a mission in there later and see if anything odd happens. I do know I've had 109s engines die on me for reasons I wasn't quite sure of before, but I suspect it was either warm up time or something that's missing in the hot-start state of the planes.

Okay, watched the track. Your oil temp went out of range high. You're not managing your ATA. MW50 comes on at much higher throttle setting than the maximum ATA you can sustain. Make sure the oil temperature stays within the narrow bracket near the top of the scale.

I've been flying the same mission over and over for the past month. At least before the main April update. IA - Thunderbolt furball. Always the same way:

1. 0-1000 m

2. 350-450 km/h mostly

3. yankinkg the throttle (Xbox controller)

4. not touching the radiator flaps knob

5. MW50 used CONTINUOUSLY, sometimes over 5 minutes at full throttle without a single retarding of the throttle.

Before update:

No engine failures without battle damage.

After the April update:

I started getting unexpected engine failures. I think they are preceded with a pop sound. I'm going to try to grab a short track file.

Thanks I will try and take another look. 

The track will be helpful.

It took me less than 5 10-minute runs in the Thunderbolt Furball IA mission. So I'd say the bug is rather easily reproducible. The attached track file should also be less than 5 3 minute long.

EDIT:

I have too little experience with Dora to tell whether it's "MW-related" or related to some other aspects of engine operation so I'll leave the track in this thread and won't be posting in the other thread

EDIT 2:

Video uploaded. A very distinct moment when the temps go up and the engine sound changes.

@NineLine & @BIGNEWY SP Track not all to long 5 min immediately breaks the engine after MW50 activation.

thx.

After the Patch the Cooling changed overall, Oil Temperature is ok the engine will not immediatly self destruct every time i will use MW50. That is my eyes one part of the Story, but still the use of MW50 all of the sudden engine degraded and falls appart.
Had it yesterday in a dogfight in mp, short after i used MW50 the engine failed but my MP replays not working at all.
Attached a replay, but from 5 times loading it showed 2x something completly different because my replays are super unstable again, hope it will work.

Dogfight instant normady after 5 Minutes the engine fails, didnt get shot inbetween.

My 5 cents to the new behaviour of the cowls flaps. 
Cowl flaps in climb now open mutch wider, wich ok german testing did also 20° in climb and climb figures with around 23m up 1000m and afterwards to 21 are still ok.

But itself it feels artificial & my opinion, the Engine itself is stil running super hot at moment you use MW50 when you go dogfight the Dora is now unable to accelerate from slow speeds, because it is sitting there with wide open cowl flaps. when you fly only high yoyos between 300-400 kmh per hour the cowls flaps will never close.
when you dive down at same point the will close, but it feels artifical and forced because all of the sudden Water raises againg over 100° degrees and the oil temperature risies to the limit again.

can not reproduce this but in the early days the dora was pretty sure going 610 612 kmh sl at sea level, currently we are at 600 kmh sl per hour, when i open the cowl flaps manual to certain level to hold 100 degrees it is more closley to the top speed of the k4.

at least from the perspective of testing MW50 in the 109 there was not much difference in heat dissipation between MW50 or none.

In my tests is Dora 8-10kts slower in all alt. after last patch

There is a fix coming for the Dora engine, in my testing it seems fine now, if there is an issue with top speed based on MW-50 and source material its best to make a new post.

Great news!

Could you actually share what caused the engine of the dora to go bonkers?
