According to HTC charts, the P-51D WEP and military performance margin diminishes over about 26~27k altitude.
I'm assuming that the P-51 WEP system (before the water-injected P-51H arrived) used a classic 'overboost' method by just simply opening the manifold upto higher levels than '100%' under normal military power conditions.
Does that mean that theoretically, around 30k or higher (where MIl and WEP shows no difference in performance), the P-51D won't 'overheat' or meet any of the engine-related problems which are prone to mainfest if WEP was engaged for too long?
I'm think that might be the case, because if a WEP system uses the standard 'overboost' method, it'd mean that at such high altitudes there isn't enough air to cause an 'overboost' in the first place, regardless of whether your throttle lever is at 100%(MIL) or 110%(WEP). Therefore, it won't matter if you just slammed the throttle forward 'over the wire', since not enough air = not enough combustion = no overheating.
Would this be the case?

Yes, that will be the case.

I read a book in high school that was full of first hand accounts from P-51 pilots. It was about 350 pages, and titled P-51 Mustang. In one of the accounts, a pilot was on the deck after escorting bombers. Some fighters jumped him, so he engaged WEP and flew all the way home from France to England with WEP engaged.

France to England can be as short as 20 miles :P
