Alright I know that in order to activate GM1 I must reach 10000m, my first question concerns whether or not I should throttle down when I'm going to deactivate MW50 and activate GM1. I'm under the impression that doing this stuff is suppose to ruin your engine at high RPM. Now here are ma'main questions. Is it worth it to activate GM1? Should I keep the GM1 activated once I get it to activate or should I only be using it at +10000m and switching back to MW50 below 10000m? Finally, a slightly of topic question, is it just me or does the 44'Dora seem to hold its E better than the Ta at low to medium altitudes?

Regards,
Fish

throttle back quick & hit your GM-1 on ( i dont bother to let engine RPM die down to idle , just off & then back on with the throttle when GM-1 is on)

the Ta has big wings , i dont know the induced drag of them , but it probably was more than the Dora seeing as they are a very similer fuselarge , so as you decend to thicker air , the plane with less drag should keep speed better

I was under the impression that GM-1 is to be activated at 9000m, or am I wrong?

The '44 D-9 should hold it's E better than the Ta at low to medium altitudes. It has C3 fuel which allows for a higher engine performance.
The D-9 '44 is equal in climb to the Ta up to 6000m(and superior to the '45 D-9). The D-9 '44 performance superiority is only noticable in climbs, its acceleration and topspeed at SL is strangley enough inferior to the '45 D-9, it should be much better. http://forums.ubi.com/images/smilies/53.gif

Alright thats cool, but once I activate the GM1 boost should I leave it on even as I descend to lower altitudes or should I just switch back to MW50?
This is all probably common knowledge to all u ppl but we Fish dont tend to catch on to these things(woe is me), take THAT into consideration BEFORE you judge me.

When you pass through 9000m you should throttle back and activate MW50. But I'm not sure on how this works, since MW50 was only effective up to about 5500m in RL. Maybe you dond't even need MW50 between 6000 and 9000m?

Well, IRL the max. pressure alt (Jumo 213E/F) was 10.500m - so GM-1 was activated above this alt.
So, MW50's supposed to work from SL up to 10.500m .

well the problem is, at least on the E7/Z GM1 boost does not boost anything...you get 0 performance increase but additional engine heat.

don't know about the TA http://forums.ubi.com/groupee_common/emoticons/icon_frown.gif

It's exactly the same and therefore I keep MW-50 on.

gm1 should pump oxygen somewhere into the system, if i remmber correctly. iirec someone said turn off boost above 6k to 9k, then hit boost again for gm1

last time i flew 109 wid the gm1, i got a boost from it, think below critical alt, it does nothing, then blows engine

N2O = GM1 its a known anestectic gas.

The Idea is to add additional Oxygen components to the engine reaction . So additonal engine power could be gained from it if the correct mixture of fuel and o2 was adjusted to perfect balance (all o2 react with fuel). That would be intresting to know how the gm1 injection worked in detail in the engine. Somehow the mixture must be adjusted autmatic but how ?

Ceiling is limited to 10000 m in il2 and most planes fly wrong at this alt .)
