Well, the P-47 isn't going to be doing 450mph while turning, unless in a dive.Spring '45; flying a P-47 try to turn with a Me 262 at 450 mph
One the other hand, the P-47 had a wing that was 28% bigger than the wing on the 262.
Even if the P-47 is carrying a larger percentage of it's take off fuel (having used drop tanks) and the 262 has used a higher percentage of it's take off fuel the 262 cannot turn with the P-47. The clean loaded weight is less than 500lbs apart even with drop tanks the P-47 is not going to be totally full of internal fuel.
If the 262 slows down enough for the slats to come out it is in serious trouble, if not from the plane it was trying to hit but from his squadron mates.
