We have more details and we know the differences in the motor setups.
The top speed on SL can not grow from 540 km/h up to 560 km/h just because you have radiator flaps. If you have ever seen the radiators flaps of the Fw-190 and you have a little bit knowlege of aerodynamics you will see that the jump from 540 up to 560 km/h is something different.
An ETC 501, the bomb rack of a Fw 190 for exampel reduces the top speed up to 10-13 km/h. Compared with the radiator flaps the bomb rack is directly in he wind. So why should the flaps have an effect that reduces the top speed nearly 10 km/h more?
In early 1942 the BMW 801-D2 was derated and the A-3 made 540 km/h on SL. With the raise of the loading pressure in Summer 1942 upt to 1.42 ata the A-3 made 560 km/h on SL. The top speed of 565-567 Km/h on SL is a result of the updated BMW 801D-2 in summer 1943.
