Over-revving the FW 190 D9 1945

Mind you that stops my old favourite power dive at 110% MW50 engaged diving episodes that netted me several La-7s dead back in the early days of IL-2 Forgotten Battles. The La-7 used to be uber but it could never dive with a FW190D-9 running full out

That's the problem though, and that's how I burned the engine, running from a La-7. Sometimes you have to dive full out. Switching to manual pitch and setting to near 0 helps.

Hmmm, and since AI uses the engine very carefully, this explains why it is so easy to shoot down even a diving D9 in a La-7.

La-7 should not be able to get anywhere near a FW D-9

Especially in a dive............

For 11 years the La's have been "hotly debated" creatures.

This was online. He couldn't follow me and I did manage to get away, but my engine died a few seconds later. So yes, the La-7 can't dive as fast as the D-9, but unless the D-9 pilot is super careful about his engine management then he will cook his engine while doing so.

This seems like a bug to me, it's almost like the pitch control system doesn't know to reduce pitch at very high speeds. I'll submit in the team DT thread.

AI or human?

No I don't think it should either. If given time to accelerate it should be fine... even under the current conditions. Even before the max VNE, the La-7 begins to shed controls. The FW190D-9 can keep going... it's just the engine you need to worry about right now.

Human La-7 vs AI 190D-9. AI maybe a little bit too careful with the engine. A human would still outdive the LA-7. It just needs a little abuse of the engine, just enough not to damage it. AI cant do that.

Of course, in reality it was easier to do it, La-7 wasnt that good even at medium altitudes.

How lucky we are to have actual WWII vets here to tell us how it was back in the day!

Anyway I just dove the 45' D9 from 5000 meters at full throttle with MW50 on and hit 870km/hr. I leveled out above the ground and held a speed above 800km/hr for quite a distance. Once it slowed down to 800km/hr I pulled back on the stick as hard as I could to see what would happened and that did not present any problems either except for a bit of a blackout. The plane made a few noises but no parts actually came off.

Now of course I fly only the official version of IL2, so I can not comment on how any of the various hacks/mods various people and their wet dreams have dumped onto the community......

I've done it a couple of times and then not again for ages... How many times did you try? I also only fly stock.

BTW: You've attributed that quote to me which is incorrect.

I only fly the stock version too. Did you spawn at 5000m in quick mission or did you climb first to get your engine to normal temperature?

I can consistently fry my D9 1945 engine with this procedure:
- pick a summer map in QMB
- start at sea level, set radiator to automatic, turn on MW50
- climb to 5000m keeping the engine just under overheat temperature
- push throttle to 110% and dive steeply to reach 850km/h as soon as possible
- lessen dive angle a bit at 850km/h to avoid disintegrating, but try to keep it between 850 and 880 until you're on deck
- level out and run as fast as you can as low as you can as long as you can

I will get the overheat message right around the time I hit sea level, sometimes a bit later sometimes a bit sooner. Just seconds after that I will hear the engine make worrisome noises, and seconds after that it will die.

I find I can delay the fried engine if I set the radiator to "open" rather than "automatic." However, no matter the radiator setting I can't replicate this problem in the D9 1944, which does not have the MW50 but another boost system, or the 109 K-4 C3, which has the MW50 but another engine, or the Ta-152 H-1, which has the MW50 and I believe the same engine as the D9 1945.
