BTW most if not all of the Spit VIII were sended to Extreme east, so that excluded them at all in ETO.
The VIII was if anything, slightly lesser in performance to the equivalent IX . Both had F,LF,HF types, but VIII was little bit heavier.
Those tests between the spit and A3 - the A3 had a sick engine.
I've heard that
many times before, but would someone care to
reference it please?

Besides that fact, the Spitfire
F.IX was run at only +15lbs boost, when it could go up to +18lbs emergency, or even +25lbs with 150 Octane fuel...
So lets see the numbers from the
USN Fw190A-5 test then, since the ADFU Fw190A-3 was "porked".
Max Climb: 4000fpm at 4000ft.
Top Speeds: 341mph S/L, 415mph 22,000ft.
Spitfires, from
here.F.IX
Max Climb: 3860fpm at 12,600ft.
Top Speeds: 326mph S/L, 409mph 28,000ft.
LF.IX
Max Climb: 4850fpm at 6000ft.
Top Speeds: 336mph S/L, 407mph 22,000ft.
HF.IX
Max Climb: 4700fpm at 12,000ft.
Top Speeds: 329mph S/L, 415mph 27,800ft.
VIII(LF I believe, Merlin 66)
Max Climb: 4610fpm at 6,400ft.
+25lbs: 5580fpm at S/L.
Top Speeds: 338mph S/L, 405mph 20,200ft.
+25lbs: 362mph S/L, 409mph 14,000ft.
