Not to mention the fact that 47N has 8 Brownings, and 20 seconds of boost. Heavies may keep up, but most LF will loose breath. Plus, 900kph dive speed is nothing to sneeze at. I'd agree with zen here, you're doing it wrong.
Also, wrong examples. Fw 190 A-5 doesn't exceed 700kph; 109G has lower dive speed AND lower max boost speed; Me410 doesn't exceed 700kph neither, dive speeds are lower than that of the 47N; 109Z is faster, but again has lower dive speed; so does F7F - faster in level flight, lower dive speed. Only P-51D outmatches both level and dive speed of the Jug. Don't panic, check your numbers twice. Important factor: while your max level flight speed varies depending if you sport ordnance or not, dive speed remains the same regardless of it, and for the Jug it's one of the highest values around.
