Would like some help on this topic. When do I use the MW50 boost in these aircraft ? In particular the BF-109. Some versions of the BF-109 has this feature but I don't know what it is for or when it should be used ? Any help would be appreciated.

MW-50 can be used at any altitudes.

Engaging MW-50 at high power will cause engine to break down, so throttle down before enabling it, then back up, over 100%.

MW-50 increases power, and roughly doubles the safe 'engine overheat' duration to about 5 minutes (more or less depending on speed, altitude, and radiator position) in the B-109K4.

So throttle down to 0%, engage MW50 and then throttle back to 100%?

It will begin injecting at 101% and above.

in the 109s you have MW50 fluid for 26 minutes use (only over 100% in use, as already mentioned). deactivate the MW50 when fluid is emtpy ( manifold pressure gauge drops) - otherwise engine gets damage.

the MW50 of the Fw190D'45, Ta152s has fluid for 35 minutes.

I engage it when engine works under 2,000rpm.
Never had any troubles.

As long as you are not over 100% when you engage it, it will be fine.

Yes I checked that "new" (?) "feature" and you're right.......engaged several times on 90-100% and no harm was done to the engine lol

Wasn't it different in some old patches?
AFAIK you must have throttled back significantly prior to MW50 engage?
