I thought the Spitfire could generally turn tighter than a Bf 109, at least for the average pilot. It was harder to make the Bf 109 make a tight turn, and inexperienced German pilots had trouble doing it, though with an expert a 109 could turn tighter than a Spitfire.
One consistant advantage of the Spit over the 109 was range. (by ~25-30% better for normal range spitfires depending on comparison, as high as 50% in some cases)
This what RAE concluded on the matter :
When the Me.109 was following the Hurricane or Spitfire, it was found that our aircraft turned inside the Me.109 without difficulty when flown by determined pilots who were not afraid to pull their aircraft round hard in a tight turn. In a surprisingly large number of cases, however, the Me. 109 succeeded in keeping on the tail of the Spitfire or Hurricane during these turning tests, merely because our Pilots would not tighten up the tztrn suficiently from fear of stalling and spznning.
...
The gentle stall and good control under g [of the Me 109] are of some importance, as they enable the pilotto get the most out of the aircraft in a circling dog-fight by flying very near the stall. As mentioned in section 5.1, the Me.109 pilot succeeded in keeping on the tail of the Spitfire in many cases, despite the latter aircraft's superior turning performance, because a number of the
Spitfire pilots failed to tighten up the turn sufficiently. If the stick is pulled back too far on the Spitfire in a tight turn, the aircraft may stall rather violently, flick over on to its back, and spin. Knowledge of this undoubtedly deters the pilot from tightening his turn when being chased, particularly if he is not very experienced.

А откуда у Ла-7 1830 л.с.? АШ-82ФН 1850 "лошадок" же... И взлетный вес 3265 кг. Насколько я знаю. И скорость у земли не 585, как у вас указано (Ла-5ФН выдавал чуть меньше), а 613 км/ч, а уж на заводских испытаниях одну машину вообще разогнали до 630 км/ч. И скороподъемность не 3850 фт/мин, а 4764 фт/мин (24,2 м/с).Lavochkin La-7 specs:

I think.
Spitfire XIV's data is not accurate. 18lbs boost Spitfire XIV's(Jan. 44) max climb rate is 5110ft/m,
21lbs boost (Auturm 44) is more.
Engine's endurance, spitfire is better.
High altitude performance, spitfire is better.
To be frank, I can hardly find BF109K's (Aug. 44)advantage ober 21lbs Spitfire XIV.
That is incorrect, this rate of climb was obtained by a prototype a/c. The Rate of climb of the Spitfire Mk.XIV is 4,800 ft/min at 18 lbs/sq.in. boost.
21 lbs.sq.in. boost wasn't used for anything but chasing V1's, IF it was used at all.
Wrong, the Bf-109 could run at full boost for 10min at a time, the Spitfire could run at full boost at only 5 min at a time.
And at low to medium alt the performance aof the Bf-109 K-4 is better.
To be frank you don't know much glen.
Top speed of the Bf-109 K-4 is as stated 609 km/h at SL and 719 km/h at alt:
BTW, MW50 is philter, harmful to BF109's engine
