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.

E-85 will do the trick also.



It has a higher octane rating or knock resistance due to the fact that it takes MORE to do the same job that gasoline would. But with more you also get a better cooling effect and the detonation issue is less.





But yar. Alot of guys I know running water injection systems either go with washer fluid or buy off brand gas line antifreeze and mix it with water. They guys who mix seem to have the better result, and those that change over to Ethenol injection doing a marginal amount better, but it has a bit higher expense.


A+ on doing it.
