Bf110 E-2 Emergency power time limits

[FeuerFliegen]

I have noticed that the time limits until engine damage on the Bf110 E-2, that the Emergency power doesn't last anywhere near the 5 minutes it says it's supposed to, even when not at MAX Emergency power...I tested it at 2km altitude... where 93% throttle would be max Emergency; at 93% it lasts about 90 seconds; at 90% it last about 120 seconds, and even at 85%, (1.3 ATA, 2400 rpm), it only lasted 4 minutes.... to go past the 5 minute mark I had to only do 82% throttle where it lasted 6.5 minutes (approx. 1.29 ATA, 2400 rpm).

 

I was under the impression that the time given was for the MAX... max combat, max emergency, max boosted, etc.

 

I haven't done extensive testing with every plane, and I understand that there could be other factors that I'm missing, but it only seems like the Bf110 E-2 is the one that has a much shorter limit than the one given in the statistics.... like I just tested the Fw190 A-3, which gives a 3 minute time limit for emergency power, and it lasted just over 3 minutes at 100% throttle.  I made sure that the altitudes were correct and not in a supercharger's dead zone.

 

Is there something I'm missing here?

Yes, the manuals state that emergency power on the DB601 is limited to 1 minute of operation. So that's what we get in game.

The 110E2 has a mode above emergency mode, called boosted mode. If you enter this, then you'll get less than 5 mins until you exceed the limits. There still might be some funny interplay between modes (ie time at combat eats away at emergency) that I'm not aware of which could explain that you got less than 5 min at the stated emergency setting (1.3ATA 2400R/M)

The in-game manual states:

 

Nominal (unlimited time): 2200 RPM, 1.15 ata

Combat power (up to 30 minutes): 2300 RPM, 1.23 ata

Emergency power (up to 5 minutes): 2400 RPM, 1.3 ata

Boosted power (up to 1 minute): 2400 RPM, 1.4 ata

The testing I have done, you get close to the time limit by using the setting stated in the specs not the max on tech chat (1.3 @ 2400)  I would test that in a map at sea level in autumn and go from there.  Not at gaming comp at the moment or I would test it.  Cockpit clock seems spot on so you can speed up to say 4 min and then go back to real time.  Do several tests at each alt.

 

After each test, finish the mission as restarting seems to cause some quirks.

@FeuerFliegen, I did a short test with oil- and water radiator flaps opened two steps at max power (1.4ATA@2400rpm) and reached 2:30min. and with the radiator flaps one step opened 1:45min, until the left engine crashed. With max emergency power (1.3ATA@2400rpm) and radiator flaps opened two steps it lasted 7:30min. until the left engine crashed.

Are you sure, you opened both radiator flaps, oil and water, to keep the temperatures in the window, they should be?

I was definitely watching both oil and radiator temperatures to ensure that no engine damage would be caused from overheating.

But were your radiator flaps open. I am asking again, because i had this in the FW190 A5, that the engine temperature was quite comfortable with closed radiator flaps, but the engine crashed because of a simulated cylinder head overheating.I don't know, if this still works that way in the A5, but it might be the reason for your engines dying so soon.

Yes they were open... in fact I usually keep them more open than necessary.
