STEAM or WATER Injection ?

[parmas]

Hello Guys,

I have been thinking long about this and I am still not convinced which infact is the best overall when used in a gasoline forced-induction engine, in Terms of :

- Fuel Economy - Which of them has the "power" to work with the least AFR at full load?

- Air Temperature Reduction - Which of them is better in heat dissipation without reducing engine air breathing?

- Pre-Ignition / Detonation prevention - Which of them is the best safety measure?


I want to keep it as simple as possible. No alcohol can be used here and we are not taking into consideration that steam might be more expensive to run.
