I have read a little on water injection. I think i'll focus on other mods first since that is fairly advanced. Should be possible to use an engine injector to mist the water?
here in the desert when folks get hot they use lil air misters to stay cool as simple as running it off low pressure compressed air. but even such a small amount of water will drown my 1.6l diesel engine which is why i say use part of the mist. solenoid injector, no. also it would rust in no time.
My coolant runs around 200F when it warms up fully (takes a long time lol). When we hit 70-80F outside, I ran around 230F. Coolant and seals/hoses must be good since my dad worked on the car while I was sleeping (midnight shift) and ended up having the coolant hit 267F and have had no problems yet. Seems the corolla likes a nice warm engine since I get better mpg when it is > 200F compaired to 180F
if you run it that hot make sure you have as much coolant as the lable on the bottle allows or you will have localized boiling in your cylinder head. better yet run evans coolant - NO water! also you might need a fan controller with a higher temp setting or your fan will run incessantly trying to cool your engine to OEM temps.
Also I already run the lowest octane at the pump, pretty sure it is 87 which is called for in the owner's manual.
the water mist *should* allow your computer to increase timing beyond the 87 octane gas which is essentially what the extra octane does, but water has many other benefits and is almost free.
have you tried feeding your engine high pressure cool air yet. if not give it a try..
