If they were cleared for 1.98 then tuning to 1.80 B4 would be little more then flipping a switch on the DB605D. JFYI the current tuning of the DB605D would be indicated by either DB605DB if tuned for B4, or DB605DC if tuned for C3.

In order to use 1.98ata further modifications/adjustments were required even 'if' they were using C3 prior to the Mar 19 doc.


Oliver Lefebvre - "But yes the C3 was definitely scarce."
So wouldn't it make more sense they were using common B4 as the Doc says, and the rarer C3 was going to the 190's who needed it? Its not as if they had C3 to throw around.
In fact by Feb/March fuel was being decreased to non-combatant units and transferred to front line units.


The 1.98ata mod wasn't proposed/ordered until Mar 20, theres a doc further back showing this.

Hoping to find some April stuff, but looking bleak :( .

I don't actually think theres any disagrement
At least we seem to be getting something of a timeline.

If there was C3 at an airfield I doubt very much they would ship it out. They would tune their engines and use it. You yourself have stated that you've seen evidence of a G-10 unit using C-3 as early as January '45. Why is it then so inconceivable to you that some was available in February? Your document does not tell you what fuel was where in late February. You're just making assumptions.

That one G-10 unit was using C3 1.98ata for Operational Testing and is listed as using C3 on the doc. It was also the only unit Jan 45 authorised to use 1.98ata.

Thats not in question.

Neither is that C3 was avialable, it just makes sense that the only ones getting it (due to scarcity) were the units who needed it ie the 190's and the single G-10 unit that needed it, as shown on the doc.

I've said the fact that C3 was available is not in question. But from the doc it would suggest that only the units needing it got it.
That would apply to Jan, Feb also.

Actually I like your thinking -
That also means just because it was proposed/ordered that the 4 K4 units were to upgrade to 1.98, doesn't mean it happened.

Judging by the scarcity of April documentation it may just end up we agree to dis-agree :)

Of course all undocumented arguments are only assumptions. In fact proving anything from the last desperate months of war ravaged Germany is very difficult due to lack of documentation.

Yeah, but hoping I can dig up at least something, you never know, but it's looking real bleak for April 45.

Was hoping somebody here would share some links to docs.

Yes April '45 was very bleak indeed for the Germans. Not many would be occupied with performing tests and filing reports. Most were too preoccupied with burning every document they had.

Nonsense, you repeat over and over that C3 'is in doubt'...

In fact just a few posts up you stated this...

Quote
neither you of Kurfurst can't/won't provide any evidence of C3 usage


You keep changing your line of argument. As I said the fact that 1.98 ata /C-3 was used is not in question... Its just a matter of how many...

You want proof go over to Butch's (Olivier Lefebvre) forum ( All About Warfare II - Aviation Board) and register and then ask your questions. Or you can do as I suggested and search this forum for his previous replies on the subject...

It now appears you have changed your tone once again to accepting that 1.98/C-3 was tested and used by at least some 109s...

The next post you will be denying it again...

Also Italian 109 units were received C-3 from the Germans from Nov '44 at least until December '44. Kurfurst has shown that Italian ANR units had C-3 in 'storage' in April and May '45. Search this forum and you will find the image he posted. He also notes his source...

Geez just go twisting things again.

If you read and reread the posts all the way through all I have been skeptical of is Kurfusts claims that all 79 (not even all K4s) aircraft were all converted to 1.98ata.

--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
Doesnt equate to no C3 was used, equates to I am after C3 usage figures.

In the same post I have allied estimates of ALL (B4,C3 and A3) fuel usage. Hardly supports your I said C3 was in doubt statement.

A few posts up from that I say I believe the available C3 was going to the 190 units - Hardly supports your I said C3 was in doubt statement.

Check back again I have referenced the G10s using C3 1.98ata Jan 45 for operational Testing on numerous occasions.

Since when has Italian stocks got anything to do with Germany (yes I read the same thread). No-one apart from Kurfy seemed to think it had anything do it.

So yet again you go off half cocked.

Yes I did search the threads, I'm guessing because of his book Butch2k can put too much about what he knows on the forums.
But nothing there, despite reading through God knows how many threads I'm still left with the same question.
Wheres the proof that 1.98ata was used with K4's?
Lots of conjecture and assumptions and theories, no proof.

Maybe when his book comes out it will settle things.

Im pretty full of myself too:

Kev, can you tell us where you pulled this "only 45 1.98ata 109Ks"? Out of your arnold?

Just because there were over 300 Bf 109Ks around at that time, it`s a documented fact, and it`s also a documented fact that 4 Wings, which contained _142_, and not 45 aircraft, were ordered to convert to 1.98ata.

The 45 plane figure is pure bull**** coming out of only you.

The only one with the shovel is you Kurfy.

How about giving us C3 fuel deliveries, and consumption, for those 4 Gruppen that only had 79 operational K-4s with only 3-4 weeks left until the German unconditional surrender.

Do you have OFFICIAL documention that those 4 Gruppen had converted, TOTALLY, to 1.98? Or is this more dreaming speculation on your part?

Not it`s not, even if you parrot it like a madman.


Kurfurst - Well there you go again, one complete wing makes it sound like a hell of lot of planes until, you realize how many aircraft were in that wing.

One Mk XIV Wing on +21 is just one Mk XIV wing.
FOUR K-4s Wings are four Wings, four times as many, simple as that.

OK, by your own figures that puts 'maybe' 45 K-4's operating 1.98ata the 1st week of April.The war ended in May for Gods sake.

No, the "45 K-4's operating 1.98ata" is pulled out off your bellybutton and has no base.

Orders show 142 K-4/G-10 has coverted. Fact.


As I said that would make a 109K-4 on ata1.98 the RAREST bird in AH2 (45 only, and only in the last month or so of the war),nowhere near being a REPRESENTATIVE 109k-4, and will therefore not make it in.

Yes, YOU said it... and it`s hardly more than wet dreams of spitBoi.



Getting the order to convert, getting the parts and getting the time to convert are completely different animals. As I said, from your post - 79 aircraft - but I doubted that all that were converted, you stated 4.5 wings converted, thats around 45 aircraft (assuming the wings were fully equipped), so I guess I wasn't wrong or lieing after all.

Well considering a LW fighter wing was authorized with 68 aircraft, so I wonder how it is, that there were 4 Wings converting...

4 x 68 is not = 45.

Actually Kurfurst what is funny is the way you and a very few other want the rarest uberboosted LW planes and yet scream like hell when a Spit is suggested that operated in higher numbers.

Actually it`s funny how WetSpitBoi crying like a baby when it is mentioned that a slightly higher boost with about 150 more HP was cleared in Feburary 1945, and used by four fighter wings with 142 aircraft from March 1945.


45 109K-4 vs 100 spit XII (all operational), and theres no way we would get a Spit XII.

Actually it`s 1700 K-4s vs 100 Spit XII, the rest is SpitBoi`s Wet Dream. But yeah of course, get the XII, no problem with it.

Only YOU have problem of getting variants that can give ya trouble.

Or 2 squadrons of IX (40-60 ac total including spares etc) converted AND used 150 grade as early as May 44 (got scan of sqn records).Yet there is no way we would get a 150 grade IX. Why use 40-60?

A RAF sqn is 20 plans on paper, 8 of them being spares, and often they fell down well below established strenght as it happens in war. Two RAF sqns are 40 planes, and much less in practice, the rest is SpitBoi`s Wet Dreams.

But of course, get the +25 lbs MkIXs, I am all for it. True it was rare in 1944 (2-3 Sqns operating), but there were plenty from 1945. You see, I have no prob with having 'best' variants on the other side... only YOU have.



Well your LW strengths include non-op aircraft.

But that`s just the BS lies of SpitBoi Kev.

Its not even a case of best vs worst (in fact it seems to work the other way round) -

What you want is the best rarest LW rides up against the average RAF ride.


Where you got that BS again?




If a 109k-4 ata 1.98 made it in FREE, there no reason why the XVI shouldn,t be in at 25lbs boost (more common than a k4-1.98 in April '45) FREE, or even a IX at 25lbs boost FREE (definately more common April '45).

I am all for free MkIX/XVI at +25 lbs boost.
1.98ata K-4 would make a nice low-perk plane, considering the 109K was widespread, and there were about half of them running at 1.98ata.

So what rarer? 60 Spits minimum Jan 45 at 21lbs boost, or 45 maximum K-4 ata1.98 April 1945?

But that`s just WetSpitBoi`s own fantasy without a base, fictive numbers pulled out of the ass, so why take it seriously?


As usual you muddy the waters by mentioning total production numbers, we are not talking total production numbers, but a small part of those numbers. Even that you got wrong, 800-900 Spit 14? In fact 957 were produced.


Yes, 957 includeing Fighter recon variants and post war production...



I too urge people to visit his site - use your common sense and you'll realize a 109-k4 1.98ata is as rare as rocking horse sh**.

Well I urge them too. It is useful to see what a pathethic liar SpitBoi Kev is, who is distorting and maniplulating the sources stated there....

Dated July 28 2005.

C3 fuel stocks- needed for 1.98ata

23 april 45- 116,000l
28 april 45 - 80,000l

This he says demonstrates heavy reiliance on C3 fuel - DOES IT

116,000-80,000=36000/5 days = 7200l per day

Divide that by 400l (fuel capacity of K4/G10 without drops) = 18 sorties per day.
Even allowing returning home with 1/4 tank that only = 24 per day
These are total sorties for ALL C3 1.98ata aircraft not just K4

Ok benefit of doubt:
They all returned home safely with a 1/4 tank
NONE were shot down
NONE were lost on the ground
NO aircraft flew more than 1 sortie per day (ie 24 sorties, 24 aircraft).
Even allowing for a 50% swing on odd days i.e 1 day 12 sorties, next day 36, that still isn't even 1/2 of the K4 available, and that still assuming ALL C3 went to the K4 only.

So we have an average of 24 sorties per day for 5 days for ALL C3 aircraft (K4, G10 etc), and this supports 79 K4's all running 1.98ata?
What is more likely as I have speculated is that very few of the remaining 79 K4 could use 1.98ata.

The more you dig into Kurfys 'assumptions' the more unbelievable they become.

So Kurfy get all the benfits of the doubt and it still doesn't add up: Is it just me or can anyone see the flaw in Kurfys logic, if its just me, please say so.



The problem is that Kev is getting lower and lower into the sewer of lies, manipulating every info in desperation..

I posted this info on ubi.com, and also at butch`s board. It shows the C-3 stock of a single Italian 109 unit, that had 39 109G-10, 3 K-4s and 30 G-6s/G-14 : 72 fighters in total.

Kev grew happy and came up with an absurd story about it, that it`s kinda the entire C-3 fuel stock of the Germans in 1945, which the Germans would need to share along all units etc. etc.

It`s simply not. NOT for all the LW, all 109 units, or all 109K units as Kev likes to twist it.

This is not consumption either, it`s simply the stock state at day. Consumption figures cannot be exactly deducted, as supplies were recevied and this made up for some of the consumption : ie. on April 29th there was 10 000 liter C-3, a day late 13 000 liter. Perhaps the 109 could make fuel, too? :lol

Just the fuel stocks of a unit with 70-odd 109s, and they use C-3 fuel for their mounts, even when it`s not required.

In fact, it relates to the use of C-3 fuel by the Axis-Italian air force (ANR) in the last days of the war. I guess they were not preferred over genuie Luftwaffe units in being supplied with high octane fuel...

Noteworthy that this unit is not even listed as having to convert to 1.98ata which would require.. in other words, this unit used C-3 fuel even when it absolutely didn`t need to...

Aircrafts of this unit :

Bf 109s
7 G-6s
27 G-14s
39 G-10
3 K-4s
2 G-12 trainers

Futher 12 S.79 transports, I take these operated on B-4.

As seen, the most important engine was the DB 605D in the 109K and G-10, developing 1850 PS w. B-4 fuel and 2000 HP w. C-3 fuel.

The DB 605 A and AM engines of the G-6/G-14 could run on either fuel, but the output would remain the same.

The fuel stocks were as the following, and suggest that the primary fuel used by the Italian 109s was C-3.



Noteworthy that the Germans choosed to supply only C-3 fuel to Italy, but not B-4.

Source : "Air War over Italy".

Moreover, the claimed specific shortage of C-3 against B-4 seems odd, in view that 2/3s of the production was C-3 grade... :

The relative volumes of production of the two grades cannot be accurately given, but in the last war years the major volume, perhaps two-thirds (2/3) of this total has the C-3 grade. Every effort was being made toward the end of the war to increase isoparaffin production so that C-3 volume could be increased for fighter plane use. The isoparaffin usage in that grade had already been cut to a minimum.

In short, Kev has no idea of the whole thing.

You are playing with the statistics again. Facts :
4 Wings were ordered to convert to 1.98ata
these had 142 aircraft
out of these 79 were operational at the moment of filling out the report

Well the Italians were supplied with fuel from Germany and nowhere else. Therefore their situation is the same as the Germans`s, their fuel came from the same stocks, and were probalbly were not preferred by the German units...

Interestingly, they received plenty of C-3 fuel. In fact, it was decided in Germany in a meeting on 8th Nov 1944  that they should receive no B-4 at all, just C-3.

Funny isn`t it, if C-3 was so rare, why it was supplied to the the 'lowly' allies of the germans instead of their own units, and why was the cheaper fuel not supplied at all..?
