Keeping it in the whatif department. Whatif they had installed decent
Turbos and Supers on the Allisons. What would that have done for even the
P-40. Afterall, later productions on the P-38 and the P-47 would have had
equal or more range and speed of the P-51C and the P-40 would have had near
identical performance and speed.

Actually -- no. The Merlin-engined P-40s still had far inferior
performance to the P-51.

The P-40N listed a top speed of 350 mph at 16,400, cruise 290; the P-51B
was 440 at 30,000, cruise 362.

The P-40Ns were equipped with an Allison V-1710. The "F" and "L" models
were the Merlin equipped aircraft.
