Over-revving the FW 190 D9 1945

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 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.
