This certainly was interesting.
comparison of FW190 A
with corsair and hellcat

---------------------------------------------------------------------------------
If you read the end of the report, it is stated that the Corsair:
1. Was run accidently on "auto lean" instead of "auto rich" during WEP testing.
2. The Corsair had the wrong prop installed.
3. Greater values in speed and climb would have resulted for the Corsair during testing.
