Alpha, that is the one major engagement that was quite successful for the 325th, to be sure, but their overall record with the P40 vs. the 109 was indeed better than their Commwealth counterparts. They simply had more seat time in the aircraft. The 325th. were also the first unit to use 1000lb. bombs on the P 40.

JtD, as you probably know from the often circulated Allison document, there were many units, both in the Pacific and North Africa running up to 72 inches of manifold in their modified P40s. They didn't all blow up doing this either. Of course those were desperate times early in the war when the Allies were searching for any advantage to survive.

The Allison V 1710 is a more robust engine than the Merlin, this is a fact. To this day you will find Merlins in unlimited class air racing using Allison connecting rods because they are stronger than the Rolls Royce units.

Looking forward to the N model.

Same is true vice versa, because usually the experienced guy knowing what he's doing beats the average guy. At least, the P-40 is good enough to allow for that.

No, of course, the increased boost did help them to significantly improve their chance of survival overall. I just meant to say it wasn't risk-free.

It would be interesting to add some P-40 variant with higher manifold pressure, if there is enough data to support it. After all there's already the 25Lbs spits, the 1.65 ATA 190s and the Bf-109K4-C3 in the sim.

I wish we could find performance figures for the AVG's Hawk 81s.

Those of us who are true believers know that their engines were assembled off the regular production schedule, and made more power than
standard V1710s of their day.

The AVG suffered higher than normal prop reduction gear box failures because of this. It also acounts for thier ability to dominate the air space they flew in. (Beyond their superior tactical doctrine). The trouble is there are no documents with numbers on them.

Hence no way to translate that into a sim, or convince those who doubt this.

Over boosted later models used by Commonwealth forces are easy to do as the documentation exists.
