Actually the German air fighter pilots were the first ones to use nitrous to good effect in their Messerschmidt BF109`s and Focke Wulf 190`s during WWII.
When a German fighter pilot got himself into trouble during an airfight against the allied airforces, he would press a button and presto chargo, an extra 300-500 bhp was at his disposal, aimed the nose of the aircraft upwards and disappeared into the clouds.
The allied pilots sometimes mistakenly claimed a victory when they saw smoke coming from the German plane, but that was the overrich condition from the nitrous setup.
From the books I've read it seems Germany, America and Britain ALL used nitrous oxide on planes in the 2nd WW.
It was first used to compensate for lack of oxygen at altitude on bombers, so they could fly high enough to avoid the problems of lower level flight. It was soon discovered that as the planes descended while the nitrous was still active, that performance increased. It didn't take long for them to realise that it would be handy to have such a boost on fighter planes but far from making them run rich it made them run lean and melt their engines, which would cause them to smoke badly.
It usually saved their lives (by accelerating them out of harms way and by misleading the enemy in to thinking it was going down), so a partially melted engine was a small price to pay and the engine was usually still able to limp back to base.
FYI the FIRST people to use nitrous oxide on an engine was Ricardo Consultants, who are one of the biggest R&D companies in the world and that was carried out on a BIG single cylinder engine back in 1920 ish.
One of my proudest achievements was to be commissioned by Ricardo to carry out a TOP SECRET project (at their HUGE premises), where I was acknowledged as the foremost authority on the subject.
