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.

about time you posted about it Art, nice job

1/2 gallon tank ? and you ran the tube from the hatch to the bay (make sure it doesn't get kinked) and what do you plan on using instead of washer fluid (for the winter, I would assume water in the summer) ?

the lines are all run along the door still next to the lines for the rear window sprayer. so everything is protected and wont get kinked.

for the tank, i bought a generic coolant overflow tank. its a 2liter, i think? but you can also just use your normal washer tank. you would just have to mount the pump below the tank to make it easier for it to pump.

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.

mannys kit is on order. woot for smurf piss !
