Seriously asking?
No, of course not.
We're just rushing out patches because we can't tickle you physically, so that's our next best resort.

tell me in case of 3.8.5do i need to patch it or not?
Yes you do and it will break other things in 3.8.5.
Mind you: Each BAT version is usually woven tightly around a specific Engine Mod version.
If you mix up BAT version "X" with Engine Mod version "Y", you will break things.
It's not a matter whether you might be lucky enough not to break things or not, it's just a matter of how long it takes for you to figure that you messed up things.

Hi, I wanted to report an inaccuracy in the FM.

This beauty at high altitudes reaches 810 and more km/h in game (100 more than the real one), with all the consequences also in terms of maximum altitude reachable.

Maybe too hight CompressorSpeedManifold value?

Can't reproduce.
Theoretically, if you disable complex engine management and overheating, and close the radiators all way, and keep the plane running on level stabs for several hours...
But that's not relevant.
We've been testing the plane a lot, and within reasonable time, complex engine management turned on and radiators opened to keep engine speeds within limits, the plane hits 700~720 kph quite well.

Maybe I expressed myself badly. I mean the maximum speed it reaches IN GAME is too high.

I noticed this by playing one of the single missions in BAT. I could keep a cruising speed of 750 km/h with full open radiators and 95% power.

With full power it outpass 810.

Max speed in RL is about 700

My modified FM for who want use it

https://www.mediafire.com/file/aqew4od80nde03j/B36/file

Top speed (with or without jet engines) close to real life.

Simply drop into B-36 folder or into Classes-FMs folder if you have BAT

The emergency and water injection power is a take-off power setting. It was available in real life in that role too, not as a continuous operating power setting. 

Il-2 runways are too short to get substantial load off the ground otherwise. It's a bit of a tradeoff for gameplay.
The jet engines are set to have overdrive intentionally (I saw you took that out) to enable the player to push all engines into overdrive on take off with one control lever. With your FM, you can't go beyond 100% unless you control jets and props separately.

The current FM was judged with 100% power basically.
There I get top speeds of ~ 585 kph for B model and 725 kph for a H-III at 10K

Of course, if you burn continuously at 110%, you will go beyond, (and get ringing ears from the screaming wind noise) but that is not how you fly usually and not how you determine the "top speed".

If you look how the USAF rated their planes at the time it gets even more complex. The numbers are more complex than just a single top speed figure.  The system took into account the weight of the aircraft (which is scaled down in Il-2 for the sake of being able to take off with any load at all), as the performance over target was deemed the essential. And these tables can't be reproduced 1:1 with what we have here. To interpret them is a science on its own, and definitely more complex than letting it run at 110% power for ten or more minutes. Measured by that rate you'd end up with a probably too weak aircraft in "normal" or "usual" operating settings.
As a pilot states, The peacemaker always had plenty of power if you needed any, it had an overpowered feel.
My 2 cents on why we left it that way.

But this is just fine, no argument against your FM, just some things we thought over when making it the first time.

I reach also 815 khp with standard FM, seems a bit too much ;)

Reading books the top speed seems 620/630 khp only with piston engines, 70 khp more with Jets, between 11.000 and 12.000 meters circa.

The limit is aerodynamics, which beyond a certain point requires exponentially more and more power.

So, I think that max 710 khp in overheat is ok.
