Messing around with matching up different planes, I find that I am terrible at keeping my K4 engine humming for any extended period of time:

Cruise around 70-85% power it works fine, but while engaging bandits, I find that the engine is very short-lived for me. Should I not push the throttle too quickly (e.g. 80%-95%, or 50%-85%)? And, if I ever use the WEP boost, the engine starts to whine and most power is lost (I'm fairly conservative with the boost too, engaging it below 100% and easing it up to 104% or so).

Thanks for any help!

engage boost at idle
and use auto prop pitch, or ull most likely cook the engine like i do..

I'm not a regular 109 pilot, especially the late-war models. However, according to
http://mywebpages.comcast.net/Tailspin/fbengines.pdf

"MW50 Injection System turned on/off at engine idle or <50% throttle to prevent damage. Switch off when run out of water-methanol mix else risk damaging engine."

As I understand it, the MW50 mixture allows the engine to be run at a higher manifold pressure. Running the engine at above full throttle (100%) without the MW50 is likely to quickly cause engine damage. Apparently the MW50 also requires some considerable slack in the transition. Try throttling back, engaging the MW50 and then advancing into the combat power range. I don't know how to tell when the MW50 supply is exhausted or how long it should last. Probably 5-10 minutes?

Don't know if this might help:

there is about 45 min of MW50 and can be used in FB for 2 minutes and then 10 minutes cooling thenit can be turned on again. Though as to whenis exahausted most likely your fuel will be gone before anything else ;D

Thanks a lot. I see now that I was completely wrong http://ubbxforums.ubi.com/infopop/emoticons/icon_redface.gifops: when I engaged the MW... . I'll try idling or <50 throttle setting and experiment a little.

Is it too hard on the engine to push the throttle too quickly? (Even from 10%-70%)
