View Full Version : Question about the 109's

02-07-2007, 10:29 AM
What is the correct way to use the boost in a 109? At least half the time I use it, it shreds my engine.

You gotta engage the boost at low RPMs otherwise it'll seed your engine.

The best technique is to engage it right after startup on the ground. It'll only switch in when you exceed 100% power.

Only engage the boost at low RPM's. Throttle back then engage the boost.

and i forgott, enable and use the GM1 of the Bf109E-7/Z only ABOVE 6000m MSL !

MW50 fluid for 26minuts use.
disable the MW50 when fluid is empty !

you can fly the whole 26minutes with cooler open, MW50 enabled, at 103% without getting any engineoverheat.

Thanks guys! 26 minutes? Dang, I never last that long online! Hopefully, you have contributed to the deaths of many http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif.

I engage/disengage MW50 below 2000RP/M - works for me http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif.

02-07-2007, 07:23 PM
After 26 minutes, the MW50 fluid will be empty? Does this sim has limited MW50 fluid? How can I check the fluid level? If I don't disable it after it runs out, what will happen? So is FW190?

02-07-2007, 07:25 PM
You will notice that your engine RPM is dropping down. You must disengage it then. Otherwise you know the drill "squeek..." and that's it. http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif
There is no way of checking MW50 level.
But consider this: you have fuel roughly one hour of flight, fight included. Bf-109G10 has even less than that. How can a pilot spend half of that time running on full military power?

That is not a normal thing to do anyway. http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif

I've run the water tank in my Jug dry many times, takes about 45 mins. http://forums.ubi.com/images/smilies/59.gif This is usually when I'm engaged @ 7k+ for long periods, and I sure notice when it's gone.

Then how long will 190's MW50 last?

Fw190D-9'45, Ta152H&C have MW50 for 35minutes in game.

the Zero Model 52C and 62 have MW for 18 minutes - used also below 101% powersetting.

well, the MW for the J2Ms,N1K2-J, Ki-100,Ki-84s, i have not seen so far that it run out.............
and its also used at 1-110% power

02-08-2007, 03:55 AM
Then what about Antons?

the other Fw190 has no MW50. they have an additional fuel injection system as boost.
so, as long you have fuel in your tanks, you have fuel for the boost http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

Nice, but what does D9' 44 use?

additional Fuel injection system. like the BMW801 Fw190s.

you needed higher octan fuel to make this possible - therefor the Fw190A/F and the D-9'44 used C3 fuel.
the idea behind the D-9'45 is that it can use B4 fuel (the same as the most 109s used) but can raach still almost the same max power because of MW50 use.

Just dont run erhote nostlestung (sic) with a fuel leak, the WEP makes it suck fuel like a pig.

It sprays extra fuel into the engine to give it the boost.

FW190+WEP+Fuel leak= 3 to 4 minutes at the most.

I always switch MW-50 on immediately after starting the engine. Works for me. I've shredded the engine only once, in a BF-109G-6/AS, when I appled 105% throttle, MW-50 switched on, and rads closed because I had to catch up with a Yak-3 I was pursuing. Even then engine damage was not serious (there was smoke and I couldn't go faster than 350 km/h).

02-08-2007, 09:33 AM
Here is what I do, I'm no guru or expert but it works for me ....
like above keep power under 99 to not blow a rod
I use Boost on take of and to climb to 3000m @ 250 kl or more speed. Then climb from then on at 75% power.
Then Ill start hunting for targets when I see a con(Dot) Ill work into a position to correctly ID it.
If its a bandit Ill dive in or merge depending on My SA at the moment.
If I know im going to merge and zoom up Ill kick in the boost and slam full power on before the merge.Building lots of "E"(Energy)
If I'm going to merge with a break turn I wont use it until I want to bait the bandit in.
I.E. as he starts to chase me
(thinking I'm at full speed) Ill kick on the boost and climb away until they wash out.

Then roll in on them with boost on and chopped throttle.
This way you have the boost(power) when and were you need it.
This "in the bank" extra power comes in handy if you convert it to altitude because that altitude is then converted to "E" or speed and Speed is life in a 109 or any Ac for that matter.

Also in a 109 you will rarely over heat in the "heat" of a dog fight
Hope this helps a bit

02-08-2007, 10:01 AM
I never knew the boost lasted so long. I fly dogfight maps with about 50% fuel. I have always been so conservative with it. There is absolutlely no way I could run out of boost before getting shot down or running out of ammo. Funny though, not knowing this has had to make me a better pilot.

MW-50 was only consumed if the boost was enabled first ('W' in game on), AND the throttle was pushed over 100%. In other words MW-50 was only used/consumed at maximum power, and then by a fixed rate of 150 (DB 605 AM, ASM) or 180 liters (DB 605DB/DC) per hour. The MW-50 tank held 70 to 85 liters of MW-50. Basically, it's good for about 26 minutes running at WEP. Never gonna happen in real life or in the sim for that matter - half an hour at WEP would run your fuel tank almost empty anyway. 10 minutes of continous use was allowed at a time, with 5 minute interval at a lower engine output to let the engine cool down. I believe the P-47 carried much less MW booster, I recall some report noting climb to altitude could not be done at WEP because water injection running out.

If there was a misfunction or in the unlikely case of the MW-50 tank ran out, there was a pressure gauge for the tank, ie. sudden pressure drop would indicate the pilot some SNAFU turning up and to switch off the system, but there was no 'how much MW-50 I have still' gauge - it would be rather useless anyway.

As for use of the MW-50 system, I never had a failure with it. Simply enable it when starting up the engine, leave it ON. It only works if you push the throttle above 100%. You can hardly ever run out of it.

How long will P47's booster last then? Is it modeled correctly in game?
