What about the Ta152? I thought I read somewhere that the yanks saw 490+ mph in level flight in post-war flight testing of one.
Trouble is, there were so many fighters around the 430-440 mph mark (Spit MkIX onwards, P-51D/H, Me109G, Fw190D, F4U-1, P-47D, Yak-9(?), Typhoon/Tempest, Bearcat, Skyraider etc etc), who knows what did what on the optimum day/altitude/tuning etc.
