The air to air ratio of P-51 vs LW victory credits using the same formula and evaluation techniques was 50% higher
A simple question - maybe someone knows how much power the R-2800 'B' in the P-47D was delivering when operating on 70 in Hg (ie. while using 150 grade fuel + water injection)? On 56 in (130 grade + WI) it was ~2300 HP, at 64 in (130 grade + increased amount of WI) it was ~2535 HP. On 52 in (130 grade, no WI) - 2000 HP.
added: seems like that at 66 in Hg, 2600 HP was available (here)
Can you elaborate on that. I have always thought, that the success of of the P-51 was mainly because of its greater range, giving more shooting and strafing opportunities, especially when Germans were perhaps not expecting fight so far east.
Tomo, check Power in Level Flight P-47D 42-26167 for power of a P-47D equipped with a R-2800-63 operating at 70" Hg using 100/150 grade fuel with water injection.

You said:
"victory credits using the same formula and evaluation techniques was 50% higher"
To reset the quote above. The victory credits of the P-51 vs LW compared to losses against the LW in air to air combat was 50% higher (10.3:1) than the P-47 (7.3:1) really says nothing regarding range comparisons. I would say range advantage gave the Mustang more Opportunities over the P-47 to Engage in air combat but does not give the P-51 a performance advantage once engaged with the LW.
I said :
"success of of the P-51 was mainly because of its greater range"
I would agree that the Quantity advantage of the Mustang air to air victory credits was due to two factors. Range is one for the reason stated above - namely more opportunities to engage. Performance advantage of P-51 over the P-47, IMO, is the reason for the higher victory credit to loss ratio.
Your tables don't give any evidence one way or the other. i understand that taking account of the range (of the credits) is very difficult, if not impossible.

1. The quality of German pilots plummeted at the same time when all of the 8AF FG's (save one) were being equipped with the P-51.
This is where I disagree. 4 points to consider:
1. The quality of German pilots plummeted at the same time when all of the 8AF FG's (save one) were being equipped with the P-51.
2. At the same time the numerical superiority of the Allied AF's increased from manageable to impossible.
3. It is said that most of the pilots did not see the attacker who shot them down. So the performance difference obviously does not matter in these cases.
4. Relating the above, the P-51 pilots had more opportunities to such attacks (due to that very range), when German pilots were taking off, climbing, landing, not expecting to be attacked.
Sidenote:
You have a habit to put your answers inside other peoples posts. This makes direct quoting impossible. Just FYI.
Your point 1 is simply not true. Throughout 1942 Luftwaffe training programmes were curtailed, redesigned and cut back or in some cases completely suspended. They never recovered to anything like the programmes they had previously been. I covered this with relevant data, particularly about fuel shortages in the training programme and lack of instructors elsewhere. I have data about the drastically shortened courses somewhere. It was not possible to turn out pilots of the quality of those trained in the pre war and first two years of the war in such circumstances.
Of course there were some experienced and formidable pilots still present, there were still a few left at the end of the war, but the overall quality of the Luftwaffe's pilots had declined sharply.
It is interesting that by 1944 both British and US combat reports start to mention Luftwaffe pilots bailing out as soon as they were shot at, or even before combat was joined. That didn't happen earlier. It was by no means common place, but it is a clear reflection of the low morale and lack of fighting ability of some young pilots. I for one will not judge them for that, some of them could barely fly the aircraft they were supposed to fight.
Between September and December 1943 the Luftwaffe lost 2,967 fighter pilots, 141% of its average strength of 2105 for that year. Between January and May 1944 the Luftwaffe lost 2,262 fighter pilots. That's 99% of its average strength of 2,283. Such figures would be inconceivable to the RAF or USAAF. Is it any surprise that Luftwaffe morale was fragile?
By 1944 the average Luftwaffe fighter pilot had a total of about 120 hours flying hours, 20 on front line types if he was lucky. His US counterpart had nearly 400 hours total, about 150 on front line types. That is no contest.

There is an additional factor working Against the Mustang, which is range related - namely internal fuel remaining when drop tanks are punched to engage. The internal fuel for the P-47D, prior to June 1944 were all 305 gallons whereas the Mustang was 269 gallons.
The Mustang burned perhaps 5 gallons for warm up and take off from the left main, then switched to burn 0-25 gallons from the fuselage tank depending on the range. The P-47 would burn 50% more for same warm up/take off before switching to Drop tanks so best case for maximum internal fuel in ~ 295 gallons and the Mustang for best case maximum internal fuel is not to burn any fuselage tank fuel and have 264 (269 less 5 gallons) gallons.
The fuel remaining after dropping tanks is
P-51 - 264x6#/gal = 1584 pounds. The Gross weight less external tanks then is about 9260 pounds for P-51B will full ammo and 264 gallons of fuel. The Fuel wt. to mission wt. = 1584/9260 = 17%
P-47D - 295x6# = 1770. The Gross weight less external tanks then is about 13340 pounds for full ammo and 295 gallons of fuel. The Fuel wt to Mission wt. = 1770/13340 = 13%
Under the assumptions that engagement begins before all external fuel has been consumed and nearly full internal fuel remains for both ships, the P-51B is paying a heavier price relative to proportionate maneuverability based on fuel remaining.
Back to the question - Does range potential help or hinder the Mustang more than the P-47 in air to air combat during Penetration to the target where most air to air combat occurred? I would say yes and that the explanation for the higher air to air ratio's to losses for the Mustang is due to inherent greater maneuverability - not range.
Clearly my example is Not a proof.
