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

[quicknstyle]

wow, this is pretty neat... so im assuming you can also wire the pump in with the boost controller or something to engage when you hit a certain boost level huh? bad ass, also, would this be of any use for a na motor? or primarily for fi because of detonation and all

see the brass switch in the last pic? thats a simple pressure switch that you hook up to a vac line. then you turn the dial on it to set it to what boost level you want it to start spraying at. this way, it only starts to spray under hugh boost and high load conditions. i have mine set to start at around 10psi.

water injection is really meant for turbo or supercharged cars. on an NA car, it wouldnt really benefit it much unless the motor was very build up, high compressor, lots of timing advance...etc..etc... you would also need to find some type of WOT switch to activate it, because the boost pressure switch would do nothing on an NA motor...... in other words.... for your normal 7afe, 5sfe, it will pretty much have no benefits.

i was thinking more along the lines for a buddies k24, but i see the point... wow, another gift for me to buy for my swap im prepping for

[Hanyo]

good job lagos, bring in great info to the 6gc community.


i've always loved water injection kit.

[easternpiro1]

WOW LAGOS! ive been looking for a good power adder.... you say you can run up to 16psi how many more pounds is that than before? im thinking around 5psi, so youre saying that if i install this, i can run around? (stock is 15 for me)








*passes out*

i was running around 13-14psi before with safc street tuning. now i can run 16-17psi with no safc adjustments and no knock. but thats just to give you a basic example. im going to the dyno this weekend and i should have some before and after comparisons to see the exact gains it gave me.

as far as your car (or anyone else), i cant tell you what you could turn the boost up to. you really have to take your car to a dyno to see how it runs at the 15psi you have it set to now, and then decide whats best for you from there. even if your stock boost is 15psi, that doesn't mean that your car will run perfectly on our lower octain pump gas. if thats the case (as was with my car) then water injection SHOULD help you out in a big way. you could probably even turn the boost up some more beyond that, but its something that i would only do if i had a way to monitor what my car was doing at all times. i have a wideband and a way to monitor knock response. so im using those to see how far i should push things.

so basically, if i were you, i would:

1: take the car to a dyno. see how far you can turn up the boost before getting knock response.
2. get water injection. you might gain HP from it, or you might stay at the same power level. but either way, it will make the car a million times safer and allow you to run more boost safely.
3. think about getting at least an egt gauge and doing the knock led mod.
4. go back to the dyno and see what you gained.

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.

Well, this is a bit of an overstatement.

The risk with running water injection is that people can tune for it, run crappier gas, or push their cars past safe limits. Then, if the system malfunctions for some reason, knock will occur and could lead to detonation.

Also, don't forget that pushing your car harder even when the system is working properly will tend to cause greater wear and shorten the life of your engine - its just the nature of high performance cars.

These concerns would not persuade me to shy away from water injection. In fact, I think its use is a great idea (even better in an MR2 with crappy intercooling) - particularly on the stock ECU. However, to state that its "totally safe to use" is probably a bit misleading.

Art, you never cease to amaze me. I love how much you care about your engine, it has rubbed off on me and makes me want to protect it more than push it

yes, your totally right. what i meant was that it was totally safe to inject washer fluid into your motor and that it will make your motor safer by offering cooler cylinder temps. how far you push the setup after that, is all up to you.

thanks dog!

hey i wanna put something like that on my 7afte ........havent been on the interweb in a minute .....but I'm back.....where can i get that pressure switch and a water pump i wanna do everything my self....but need those two things ........and when that pressure switch is activated is that water pump also kick on or just the sprayer solenoid or am i just making things up?


i need details lagos

[lagos]

your best bet is to buy that kit. at 200bucks, it will cost you very close to the same price to try to do a home made setup.

if anyone wants to buy a kit from those guys, here is a 10% off code you can try to use at check out. code: 2d4afa
im not sure if it will still work or not, but its worth a shot. youll save like 20bucks off the kit.

regardless... you can get the pump and all the parts you need from their website. they even have the instructions online, so you can see how the whole system works
http://www.alcohol-injection.com/

[rzanology]

yea it still works...manny gave it to me to use and it took it...saved $32 off the universal kit and 2 quart tank

[southwest2118]

hey lagos on that pump can that pressure regulator be taken out? because i was thinking about getting something like this.XXXXXXXX and adjusting the pressure to like 100 psi and buying the pressure switch,and nozzle from alcohol-injection.com then getting everything else from somewhere else.

oh i've been away for a while ....what are u using to control fuel?....

i dont think that pump has enough flow and some of those pumps cant be used with meth (washer fluid).


the pump in the kit is also a shureflow pump. so if you can find the same exact model from another place, then you could use that. but why take the risk? at best, you could probably save 30-40bucks? or you could just avoid the headache by buying something that is made to work with meth and has been used by a large amount of people.

Congrats on the set up Lagos Ive been reading more and more about Wi and how its supposed to be really good for turbocharged motors. At first the thought of putting water in the engine made me cringe but seeing you and manny run it with good results is starting to win me over...



I had a few questions about the kit... How long does your tank of fluid last you? I know there are variables but an estimate of a weeks worth of driving to school, work, etc. and hit 10psi occasionaly on the freeway?



second... can you use this out of the box? or do you need to tune it in professionally? I kinda want to get all my upgrades done before taking it to a dyno... that way i dont have to keep going back. but could i use it before then?



thanks for any help... Its realy appriciated

[Steevo]

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.

how long it lasts will very on the size of tank that you buy, how soon your injection kicks on, and how often you boost. i figure somewhere around 2-4 weeks, depending on those factors. its about 3 weeks since i installed mine, and im just about getting ready to refill it again.

you don't need any tuning for this. just install it and you'll be good to go. but, you might not see any gains from it untill you crank up your boost. if your car is at 10psi now, with WI, youll be able to turn that up to at least 15psi (with a fmic!). ive seen as much as 18psi, with no knock. but keep in mind that anything over 15psi is a bit risky and you shouldnt do it untill you visit a dyno to see how things are running.

Good stuff.

Why isnt this thread in the stickies yet? along with presure's thread...

because both are, "hey i just installed this" not how tos.
one or both of us im sure will do a full write up eventually that will be in there.
