The Corsair had water injection as a WEP, I forget by what mechanism it worked but it could make that big ol’ Pratt & Whitney eat its own guts for more horsepower.
Thanks, that’s a lot more than my sketchy memory of what my dad told me (WWII pilot). Might not be where “under the wire” came from but it’s fascinating.
WEP, war emergency power. Depends on the aircraft how long you could use it.

Water methanol injection, cools the air charge which makes it denser, more air you can cram in the more fuel you can cram in with it.

TIL you can increase engine power by mixing water into the fuel.
It needs to be injected into the air charge with the best atomization you can manage for best results.
Thanks for the read, that sent me down an interesting rabbit hole
