Water has better cooling capacity than alcohol so would be more effective. A misting system of 0.5l water and a nozzle would be really light and effective for racing.
My aim is to get same reliability as a car or dirt bike so it's no option for me
Yes, but ethanol boils at about 79c, water at 100c. Cooler is better in this case. And we could reclaim the resultant vapor for later ingestion.
Build a mobile still! 2 stones, one bird! Maybe feed the flammable ethanol into a turbo unit!
I remember flying with my dad in his plane. It was a Cessna then he got a Mooney 201, and it always seemed weird to me to put extra fuel into the engine to cool it. Phase change, vaporization, etc. No extra equipment or weight, and it has worked the last 100 years. Speed cooling the engine leads to cracked blocks, and other bad things. Guess there is a reason that industry died. 1930's tech nearly 100 years later is hard to believe.
Aargh, screw it, lets just do liquid nitrogen! Too hard to get helium these days, so skip that..
