Well, if the book "America's Hundred Thousand" (Francis H. Dean) is to be believed...
TOP SPEED
P-47M = 470mph
P-47N = 460mph
P-51D = 440mph
Because of the P-47s turbo system, the Thunderbolts speed increased as altitude climbed. The P-51D speed fell off sharply above 25,000ft...
ACCELERATION
P-38L = 4.13 ft per second
P-47M = 4.02 ft per second
P-51D = 3.85 ft per second
(These data are originally sourced from the "Report of Joint Fighter Conference: NAS Patuxent Riuver, MD, Oct 1944, and reported in the many other sources. These are real data, not wishful thinking or imaginative history...)
Personally, I would have taken a P-47. I would have hated to ride the silk elevator because some jugend with a BB gun who got a lucky shot on a radiator hose...
As for range, the P-47N was the US WWII champ with the longest legs... 996 gallons would get you a clean 1000 mile range at 25,000ft with a 30 minute reserve and 20 minutes of combat time. The P51D with external tanks only got 700 miles with those conditions...
One last thing, if you are a Mustang fan, DO NOT read the comments by Naval LT Halaby on page 241 of the Fighter Conference Report... You'll only get mad and go into revisionist history denial...
