La-7 c/n 38102663 (Plant 381, Moscow) Yakubovich's factory-data table lists it as: • SL: 579 / 613 km/h • 2,850 m: 645 km/h • 6,000 m: 661 km/h • Time to 5,000 m: 5.25 min / 4.6 min

yeah i have it as 26-27 at military power in the OP now

Happy?

Here you go 613-616km/h at SL 661km/h at 6250m --- This is the crazy high quality La-7 doing like 640 at SL

597kph you have there is at military power So actually that La-7 is doing 636 at SL with WEP and 680+ at 6250m, but this is the peak ultra high quality

I did but of reverse calculation of this La-7 in 1945 with 3 x B-20 cannon: ASh-82FN: 3,223 kg. 613 / S.L. 661 / 6,000 m. The engine power curve looks like this for ASh-82FN Then i applied this power curve to La-5FN doing 583km/h at SL as per one of the test flights

Did you however take into account that XP-55 has no wing slats and J7W1 does? The reason I didn’t give single direct number but 26-27 at 100% and 24-25 with WEP is it’s both values, 1.10 and 1.15 CL
