[Mustang]

a) the system you present is a modern one - differences between modern W/M injection systems and technology from 1942 should, must be studied before claiming "the effect is the same - it cools the engine"

Water cools the engine in present and in 1942 .
Read my link
You can buy and put Water/ Methanol kit in any engine virtually, with the same results .

b) are the fluids used chemically the same?
"

Yes common wather and common methanol
No secrets here.

d) okay, so... lets take it easy. lets say, the engine is cooled. The Db-60x series are a big piece of machinery, so , more specific questions must be figured out.
-what exact part(s) of the engine will lose temperature?
-how much?
-what does that change to engine operation, and how is power output effected?

The P51 have many problems like this

C.C. Jordan=

I have data that indicates that the
P-51D, measures 48 lbs in a 3g pull. Up to 86 Lbs at
5g's.
The P-47D, OTOH, requires just 16 lbs at 3g and 27 lbs at 5g's.
The testers state that the Mustang was a true "two hander".

Just do something.
If special ignore other things

Thanks to these omissions
My P51 can be turn with the BF 109


Ok forget Mustang Sorry

Because:
uuhhh, ahhhh, modern systems cool the engine, so, in a 109 that means i get -35° temperature loss, and that again means i can have longer MW50 operation...

The luftwaffe tell you. The mw 50 not work over 6000 mts, for system freezes.

Every time you start a flight, you get a perfectly new plane - right? systems are 100% healthy. There is no option to "use the plane from the last flight" - the game does not remember if you respected the manual last time you flew it. if you used MW50 for too long (7 seconds? 2 seconds?) or if you respected the 5 minutes pause (4:55?)

Like the others planes have the same.

For MW50.
"it can only do good things. Since the water and methanol will help dissolve carbon buildup, it can keep your spark plugs, valves, and combustion chambers very clean, too!."

basically:
You push your plane to the very extreme corner of its possibilities: you die.
Do not do that, or you will die.

so even IF this system could possibly improve performance of the Db-60X powered planes...
you die.

And NOT DYING... is common sense.

I'll just say one thing

Are debunking current evidence
Of and operates water methanol.

Is a Fact
