Water injection in WWII aircraft engines was basically to prevent
detonation with high MP. Believe the Jug had it on their R-2800 P & W
engines. Could pull 90 inches with water as I recall???

Some early jets had water injection. Ferried a F-94A/B that had water.
Used on T/O and you used all to prevent any residual from freezing in
tamk and lines at altiude (-50 F).

There used to be an add on kit that fed water vapor into the carb, which
increased performance. They used them on Spitfires during WWll and on
cars in the seventies. H20 = hydrogen and oxygen.

How about one of the new miniature turbine engines used on model
aircraft. Duct it so the exhaust would feed directly into the carb of
the main engine on take off and shut the turbine off for cruise. These
cost about 1500 bucks now and weigh about 10 lbs.

Uh, bzzzzt. No. How about the nearly no oxygen content the engine is
feeding the other engine. Besides for 1500 bucks, there are proven methods.
