OH NOOO: I put Washer Fuild into my motor...., ... and it made it go faster! Options

over the past few months, ive been trying to street tune my car to get the most of out my setup. i noticed that i could run 13psi just fine, and sometimes even 14 or 15, but sooner or later i noticed that i would see knock response on my tvsv leds. after trying a lot of things to resolve the problem, i came to realize that the jdm ecu just runs too much timing advance for our pump gas. youll hear mr2oc guys always say how they keep their boost at 15psi, with no problems, but then you look at their dyno sheets and they are only making 200whp at that boost level. so, if the turbo is good for it, and we have the fuel to support it, then the problem must be timing.

so decided to fix the problem by buying water injection. i got the Devils Own water injection kit. i have it running pure washer fluid, 3gpl nozzle, and injection starts at 10psi. it made a huge difference! i can now run 16psi, with no knock and the car pulls like crazy. ive yet to try any more boost then that ( and i probably wont), but im confident that it would do 18psi with no knock, if i really wanted to push it. youll hear people say the ct26 falls on its face after 15psi.... but all of that changes with water injection. your intake charge is cooled down in a major way, and it makes a world of difference, especially on our jdm ecu's that are tuned for higher octain gas.

here are some pics. i installed it in my trunk, because i had almost no room in the engine bay. sorry for the wiring mess, i was going to clean it up before posting pics, but its just to damn cold out right now.

Sweet! Water injection is pretty niffty, at first im not gunna lie, i thought someone was really dumb enough to put washer fluid in the oil or something lol.
I had the same feeling free boosting the ct26 with the larger intercooler. basicly the same effect as water injection because what its doing is cooling the charge more. Id like to try water injection on the new setup, but im not sure if it will really benefit me, i doubt my ic will need the help.

your right, a huge IC would help out a lot too, but its important to remember that WI has certain benefits that no intercooler can achieve. "an intercooler cannot perform in-cylinder cooling". thats a pretty big benefit. its similar to what you would get with running race gas all the time.
