In know IRL there was a limit to how much nitrous or methanol\water injection a plane had (usually 15 minutes)..Its seems that i have unlimited amounts of the stuff in all ac that utilize the stuff. Is that right?...If so will it be changed in a "patch"

If i remember correctly if the mw50 is empty you will see the ata-gauge going down... and than be quieck or say goodbye 605....

it does runout in game http://forums.ubi.com/images/smilies/16x16_smiley-wink.gif, atleast water injection does on p47 and corsair and hellcat

MW50 in Bf109 = 26min
MW50 in Fw190/Ta152 = 35min
fluid for total use , sure only above 100% powersetting http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

A6M5C and one of the A6M7 , you can look at a gauge , positioned there where other Reisens have their left MG. you have fluid for 20min. keep in mind that the fluid is been used at all powersettings when activatet!

in a Ki84 you cant run out of it http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif.
nevertheless its in use at all powersettings when activated http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Thanks for the quick response. The time usage tables seem high..I just remember from the Old Warbird Days that you were given about 10-15 min worth of water injection or nitrous..
..The P47 drinks about 270-300 gal hour at full emergency power IRL. Just seems odd to get so much water injection. I havent seen any real life tables. cheers.......

I tried to do some research oon GM1 and MW50 as far as it was used..Quantity and time limits.. But have not scored yet. If anyone knows a good page, i wouldbe interested...

here is a snippet from a post i saw about the subject;


"Desperation towards the later stages of the war (deepened after the first jet aircraft proved frighteningly unreliable and, in the case of the ME163, doing more harm than good) led to investigations into methods of boosting piston engine outputs beyond the usual emergency output for short periods in the absence of high octane petrol which would allow excessive boost to be used - sprinting to catch a bomber formation, or trying to evade enemy fighters, for example. Military aircraft always have short-term power ratings for emergencies, 'war emergency rating' which will kill the engine in five minutes without throttling back, or else 'max mil' or maximum military power which is a higher output that maximum ordinary power, mainly because the Queen pays for the parts. Luftwaffe, BMW and Daimler-Benz engineers came up with two main solutions, MW50 and GM1.

MW50 involved spraying methanol and water in equal parts (hence the name) into the eye of the supercharger. This had two main effects in that it cooled the fuel/air mixture, thus increasing the charge weight, and the methanol acted as an additional fuel to complement the petrol.

GM1 was gaseous nitrous oxide and extra fuel injected into the inlet tract downstream of the blower. Again, this cooled the charge, increasing its density. The nitrous oxide also decomposed in the combustion chambers to give extra oxygen, permitting the fuel injected at the same time to be burnt. GM1 became known as 'ha-ha' for obvious reasons and, when used with MW50, would produce very significant power gains for no more than one or two minutes at a time. The Luftwaffe's greatest problem was that the fuel available to them was of dreadful quality - to help Tempests and P-47s catch V1 flying bombs in 1944, 750hp gains could be had by increasing the war emergency boost to ludicrous amounts (60psi), and using 150 octane aviation fuel called 'purple passion."


I was unaware of "purple passion" interesting though. It just seem that running your engine 15min. on nitrous would fry it..anyone have any real life data tables?

The D-9 had MW50 for 40 minutes of use. I hardly run the throttle at 110%long enough for it to run out. http://forums.ubi.com/images/smilies/16x16_smiley-happy.gif

Back in the days, late 60's, we used 115/145 avgas in the USN which was also purple in color. It was 115 octane as I recall. We called that "purple passion" too! Some other Navy and Air Force bases used 100/130.

Robban.. is that 40 min for the Dora IRL or the Game. I read the Ta152 had both GM1 and MW50 and in the Game you start out with GM1 for about 3 minutes thn go to MW50..if you run it run it long you do cook the motor. the d has 2 types of boost.. here is a clip from a post i saw as the '44 is different than the '45 model as far as boost is concerned. I have not seen the term laderdrukerhohung before as refered to the D9. What i believe so far is that boost from turbochargers, turbo-superchargers, 2 speed 2 stage supercharging, Erhonte Notleistung, Nitrous and water injection systems are alot more complicated then modeled in the game.



"erhonte notleistung is to the A series what the laderdrukerhohung is to the D9. I.E the bleeding of the airline, the depression causing the throttle butterfly to open widely so that more fuel is vaporised into the cylinders creating a charge cooling effect.

for what i have mustered the d9 could maintain his start und notleistung for 30 minuted the A9 for only3.
(they both could use their boosters for 10 minutes)


I have not being able to find any proof of operational use of the Mw50 on A series. It was not serialized in anycase." end quote'


Just give me purple passion</span>

thanks for the links..good info..Just as i thought.. ther really should be three different boost buttons ..one for MW50/water injection another for GM1/nitrous and another for the emergency boost increase if available.I am a bit of a gear head and would like more detail in the "complex engine management".

I'm frazzled trying to understand what we have!-but I get where you're coming from.


I wondered why we didnt have a dora with c4 fuel and decent high pressure mw50, but seeing these threads I know now why we ain't got them. I think...

Can't help wishing for a dora with a 1900ps (unboosted) 213 power plant though (with mw50 on top ..) and gm1..lol
