During a 4 days test (february 1943) in Guidonia (Italy), Regia Areonautica and Luftwaffe tested the Bf109G-4 and the Fw190A-5 against the "Series 5" italian fighters: the Macchi C.205V (and N type), the Fiat G55 and the Reggiane 2005.
Documents (Rechlin 1943) come from the test department of the Luftwaffe (courtesy of -IREG-). All I can say here is that:
1) The production C.205V (not the 2x7,7mm one) had roughly the same climb performance of the 109G-5 up to 6,000mt (about 20K).
2) The C.205V, combat tested against the 190A-5, reached 440Kph (275Mph) IAS at 6,000mt, the *same* speed I register with the AH C.205V. No WEP use is specified for any fighter.
The LW personnel were impressed by construction quality, armament and performance of the italian fighters.
The 190A-5 was the king of the day: faster, better roller, diver and .... very interesting is that up to 6,000mt the 190A-5 never suffered too much during climbs tests against the DB605A1 engined fighters. This could be another proof that the WB 190A-4 performance is someway tweaked down.
