Hi Tex,
>According to this site
http://www.p40warhawk.com/Variants/P-40E.htm the speed of the P-40E is 335mph at 5000 feet.
With a couple of friends, weresearched of P-40E performance rather thoroughly.
We arrived at the conclusion that the P-40E should achieve 560 km/h @ 3750 m (348 mph @ 12300 ft) at 44" Hg, 3000 rpm.
At 5000 ft, it would do 319 mph at that power setting, so the number you quote seems a bit high (or meant for a very high power setting).
>The batch Id like to see modeled in is the P-40-N-1-CU.
There's quite a bit of confusing data on the P-40N, but after a lot of research I'm confident that the speed of a properly performing P-40N-1 is pretty accurately 580 km/h @ 3048 m (361 mph @
10000 ft) at 57" Hg, 3000 rpm.

Henning (HoHun)
