P-39 Expert,
The test for the P-39N-1 was conducted at 7,272 lbs with ammunition in it. A stock P-39N-1 came in at 7,468 lbs. with ammunition in it. The only things that could be removed were amror, and it puts the P-39N right about the test weight. The climb test was at 50.5" MAP or full throttle, whichever is available. The U.S didn't fly them without armor or at that boost level in service, at least for a good chunk of the P-39's operational career. They flew them by the POH and squadron standard operating procedures, which weren't especially lenient about boost.
Get real. Nobody ever gets the absolute best performance ever recorded for an airplane in normal use, especially after a few months outside in the environment. There is nothing wrong with the Wright field tests. Just your determinination to use the lightweight WER Wright Field test results as normal for the P-39N, which they weren't.
But, I expect you'll stick to your guns even in the face of testimony from people who flew the P-39 that it was a dog in general. I bet in you world, stock muscle cars always run quarter miles in the quickest time ever recorded for a stock vehicle by a professional driver, too.
Not in the real world.
I had a good friend in high school who became a professional golfer. He told me once that par was the score an average professional should achieve on an average day, and that golf was the only endeavor where the average amateur participant somehow expected to be able to shoot as well as the average professional. Apparently, it isn't the ONLY endeavor where that happens.
Cheers.
