Water injection
 

I posted this a while back, but no one(not even jeff!) knew anything about this, there were a couple of websites, but nothing to helpful. Im wondering about gains and is it REALLY worth it. Please, anyone who knows someone, or has a friend of a friend who has it. please please please someone reply with some knowledge. I might be doin this over the summer and it would be great to have some input on it. I will of course take pictures and let everyone know the pros and cons of it.

I know about water injecton, I know how it works, but I have never tried it on any of my cars.

Re:Water injection
 

I thought I had something inteligent to say, but I forgot :(

Re:Water injection
 

I have been doing some research on this as well cause i was thinking of doing it. On some of the posts i have been reading this system is suppose to eliminate the ic. It is set up far enough from the throttle body to evaporate into a gas before it hits the engine. It like dropped the temp by like 200 degrees or something and eats up the carbon. I will try to find the website and post it for ya ;)

Re:Water injection
 

intercooler and water injection DIFFERENT ----, intercooler cools the charge from the turbo while the water injection is in cylinder ----, internet isn't always right, but i am ;D that means u need both......

Re:Water injection
 

this mike, rx-7 guy, ask and i will tell you.

as for gains? alot, cheaper gas + more boost, no more wasting money for race gas and ----.

if you have a fuel conntroller, it would help alot to save gas, u run the water injection till it studders etc, meaning your running rich, then you lean the fuel out, that way more water using and lesser fuel comsumption, get me?

water injection is good but i think alcohol is even better, low burning rate of the alcohol is like race gas, high octain burns slower, durh.

as for timming, no need to retard alot, ----, without alcohol injection for me i run about 14 degrees while in boost, if i can remember right, but with alochol im good to be around 17 degrees and still running strong.

i think the only way to really make water injection work is a good engine managemnt, using stock ecu would be ok because the octain of the gas would go up and stock ecu should see no detenation and should advance accordenly.

there much i know, just the info is for rotaries, i'm afraid of using water injection or alcohol on pistons motors because there is NO SUCH THING AS HYDROLOCK for rotaries, (true statment no lie)

-mike, your water injection specialist?

Re:Water injection
 

o yeah with a good engine magament, u can apply more advance timming and get good air/fuel-water ratio getting good horsepower and torque out of it.

maybe in the summer i'll build another kit and do step by step on a website with pics so you guys can get some info, there is more ----, just i can't remember at the moment.

Re:Water injection
 

hehehehe i like alcohol so much more then water to ;D

Re:Water injection
 

Water injection = Band-Aid

IMHO

I was just reading an article on water injection last night.. Saber Performance here in Toronto sells them.

I'm with Mike, being a rotay guy myself, I've never heard anything bad about water injection. It will drop your charge temps and it keeps your engine all nice and clean on the inside :) Water injection by its self want give you much gain, but it allows for more boost and safer boost, which will. Its a nice safety net at any rate.

check out a company called aquamist http://www.aquamist.co.uk/ they have some cool stuff. There kits are not the cheapist, but i've heard tale of making your own kits using the water pump off of an RV (you need a big pump that can pump out the water at a higher rate than you are boosting or your water will never leave the bottle)

Re:Water injection
 

band aid my ass ;D, i use water injection over much much much PSI, and still hold on, i never had to go to leaded gas or some craziast race gas, the only time i used 100 octane because my nozzle was loose and it was race night, and i didn't re program NOTHING, ran well but i but my datalogs show lil signs of detonation, i was afraid for the first time of blowing my motor, because of 100 octane wasn't good enough! sure it wasn't MUCH detonation, some people wouldn't consider it anything, but i do, being use to none or very very lil, that was too much for my blood. i think water injection bumps octane up much, because i see signs of detonation with 100 octane and that isn't good.

and remmeber start out slow, since there is no way to know what type of nozzle u suppose to use, start slowly, bigger is not always better for piston engines(hydrolock = no pretty), i say try start with medium around 0.5 nozzle and move ur way up until u feel slight rich problems, for me it's .8 for 15 psi.

Neoboi,
What else do you know about water injection? How would you say the install is on a d16z6. In the summer i overheat and run slow as hell under boost.(i live in az w/ triple digit heat) Would i still be able to boost if i use water injection? Would this make a huge diference in triple digit weather?

I am mostily concerned about the install. I would buy a WI kit, but can a newbie like myself install it?

Any info would help. thanks

Re:Water injection
 

taking corky bell's approach? There have been a few cars that came with water injection standard (the Buick GN was going to, but they changed it at the last minute). I think running it if you don't have an IC (or don't have enough room) is a great idea. If you do use alky, do a 50/50 mix, and always use distilled water.

Re:Water injection
 

Home made set up of water injection going on my car with the new motor. We'll see how it goes, only cost about $210 to get all the parts shipped to me...

Re:Water injection
 

Well essentially both Intercoolers and Water Injection do indeed do the same thing with different aproaches... Ok so an intercooler cooles the air through a medium such as alumium which is either cooled with water or air.. Water injection kits spray a stream of water into the intake path, because water has very good heat properties when the water atomizes heat is essentially removed from the intake charge..

Re:Water injection
 

water injection is simple to install if you know what your doing, all u have to do is know a little about wiring, if you know a little about installing decks and speakers, that's all u need to know, to drill in nozzles/injectors is simple to just drillin a tap and install the nozzle, make sure it's install before the throttle body and best after intercooler, and install a pressure switch if you want the water injection to come on at certain psi, simple kits that you can make is fairly cheap and works well, but aquamist and other companys make great kits but expensive, aquamist is like the ultimate in water injection, it has all these computer controls so u get extactly how much water and it's tune-able.


as for boosting, water injection is the bomb, it's tight ass hell, ;D, it allows more boost and more advance timimng with lower octane, and since ur in hot weather you would be able to cool down the intake charge and drive alot better, smoother and more crisp, no lie, but cooling the over heating isn't it's main purpose, the cooling system on your car needs to be checked first, water injection would help alot though, because water vapor takes the heat with them cooling the system down alot.

and the reason u run slow as hell under boost because the heat, and that is causing your to detonate, since ur ecu knows what's up it RETARDS the timming alot to help ur engine to stay alive, in order for it to run more better you need to let the ecu advance the time, with higher octane or water injection.

Re:Water injection
 

Get'm both, or at least water injection.
We'll see how my kit goes, it is fairly easy to set up, I say that the bitch is gonna be finding a way to mount some of the hoses around lol... guess I could drill and tap, and use brake line holders. Oh well we'll see :)
