Yo! I've recently run some top speed trials with the P-38F (using the training arena and FH 1.67, of course). Now, most sources I've seen state that the P-38F could reach a speed of 395 mph @ 25,000 feet (635 km/h @ 7585 meters). Unfortunately, our P-38F falls a bit short of those specs. Here are my results (speeds measured using the .showdata command): MIL: 603.2 km/h (374.9 mph) WEP: 611.49 km/h (380 mph) The MIL speed reading was taken when I had between 55 and 60% fuel left. WEP speed was taken at around 50% fuel left. I did take off with 100%, but airstart was disabled so I had to use up a lot of fuel just getting to the test altitude. The speeds I stated really are the fastest the plane would go. I made sure I'd wait until the speed readout didn't change anymore for a full minute.
