Read this article and you will know high-speed propeller was a leading edge issue in WWII when people didn't know much about the transonic aerodynamiacs(0.8-1.0 Mach). They even could NOT precisely test the propeller efficiency at high speed in fullscale wind tunnel.

Il2 is a very closed simulation when speed is below 0.8 Mach, but when speed of anything(wing, propeller tip,etc) is beyond 0.8 Mach, not very accurate.
