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

[lagos]

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.

im going to run washer fluid all year round. it contains about 40% meth and 60% water. the water helps cool, while the meth adds oxygen and fuel to it (at least thats how i understand it). so its best to run a mix of meth and water for best results, which you get with cheap washer fluid.

Yes water does absorb heat, however the injecting alcohol increases overall octane of fuel combusted

I am planing on getting a meth injection kit that will come on progressivley from 8 psi, hopefully i can turn 93 into 95 octane like my ecu was designed for, untill i get my PFC datalogit and tune it for. Maybe with 100% methanol injection you can add enough advance to make 93 act like 100 octane ? if i could run 18 psi on race gas safely, i should be able to do so with proper injection and tune.

Congrats, results seem promising!

you can run 100% meth on this kit as well as buy a progressive controller for it. but, from what ive read, you'll get the best results by using a 50/50 mix. the meth for the octain, and the water for cooling the boost charge.

forgive me for my noobness, but i always thought water injections was when u sprayed the intercooler to further lower the temperature of the air. but by this i guess it something that you actuall inject with the fuel??? im at work so cant read the links, but how does this work? i can understand the reasoning to use methanol because it burns much cooler than gas, but is this really something that you inject with fuel? and is it safe for continued use over a long period of time?

your thinking of an intercooler sprayer. water injection sprays the water inside of on engine to lower the cyinder temps as well as raise the octain level of your fuel. this lets you run more boost, and more timing advance and provides great knock protection. its totally safe to use. read the links when you can to learn more about it.

what all did the install involve?

its pretty simple.

you mount a tank (or use your washer tank),
install the pump,
wire in a realy,
drill and tap a hole for the nozzle
wire in the presure switch and connect it to a vac line.
