Ok, let`s deal with your points :
You say the Germans captured a P-47C without water injection. So?? Both sides in WWII captured large numbers of enemy aircraft. For example the British captures of German aircraft were substantial including :
30+ 109 E`s
20+ 109F`s
30+ 109G`s
30+ 190`s
Note, these are aircraft in either flyable condition, or possible to make flyable with minor repairs. They do not include wrecks or crashed aircraft.
It so happens that the first 190D captured was a model without MW-50. Does this mean I run screaming to the AH Bulletin board demanding that the 190D have its top speed reduced to 426mph? Of course not.
The fact is, the German`s captured a LOT more P-47D`s with Water injection.
These are the totals of P-47 models produced :
P-47B : 170 The 47B was never deployed to Europe. The 56th Fighter Group received some of these aircraft when it was based in New York, but left them behind when it was deployed to Britain.
P-47C : 602 The first 47C rolled off the production lines on September 14t h 1942, in December `42 it equipped the 4th , 78th, and 56th Fighter Groups in Britain. Last production of this model was in late December `42 or early `43. The Groups equipped with 47C`s were held out of combat until March 10th `43 when they flew their first sweep. They did not see combat until April 15th `43 when 3 P-47C`s were lost. (The 47`s claimed 3 German aircraft) Perhaps one of these was the aircraft you are mentioning. But even after that date missions for the U.S. Fighter Groups were restricted, because the aircraft were not equipped with auxiliary tanks and couldn`t escort the B-17`s any significant distance. Combat was very limited. By this time, the first 47D`s were being delivered to the Combat Groups. The existing 47C`s were also being modified. There was little difference between the late 47C and the early 47D. Their fuselages were essentially the same and they both had the same Pratt and Whitney 2800 Double Wasp engine, rated at a base 2,000 horsepower. It was a simple matter to modify the 47C`s to adopt the 47D`s engine changes. At the same time the 47C`s were modified so they could accept a drop tank.
P47D : 12,602 (note, this figure does not include the 47G, 47M, 47N etc.) The 47D`s began to equip the American Fighter groups in early `43. First models of the 47D did not have water injection, but were quickly superseded by those which did. The 47D`s came standard with a mounting to fit a center drop tank. By July `43 when they began longer range escort missions, all the 47`s equipping the Fighter Groups were either 47D`s or 47C`s modified to be indistinguishable from 47D`s.
From the above production figures, you can see that the 47C was a minor variant when you look at the number produced when compared to the numbers of 47D`s. There is no reason to incude it rather than the 47D Razorback.
Rather than trying to sabotage the creation of an accurate FM for an American aircraft, why don`t you instead put together a well thought out thread on the 109G`s with Methanol. You could go back and find my thread, (which had many positive responses) and bring it back to the top of the board with your own (I would hope) carefully researched facts.
