Water injector and how it works

[TRDmod]

Please if this post has been covered comprehensively tell me and give me a link I tried searching this time but cant find

Anwyays, water injector, the type that you literally inject water to the engine or something, that you can place before or after turbo and apparently placing after the turbo is better

Has anyone used this?

Can anyone tell me specifically the science of this and the application?

I heard that it helps cool engine and prevent detonation, applicastions for cuircuit use?

Thanks y’all aaaight

Pretty comprehensive arguement there

Theres a few people on this board running some form of Water / Methanol Injection - personally I have an Aquamist 2C system.

i built my own system in my B6 mazda worked real well, i injected after the turbo, and i used it on a manual set up only when running extra boost on the ocasional drag, otherwise have to top of the water to often

but yeah its been well covered in the other thread

I've had an Aquamsit system on my Rover 220 GTi turbo for a few years now and it has been fault free in that time. The T16s internals are exactly the strongest in the world and I am certain that it is down the the WI in a big part that the engine hasn't failed despite a hard life.
Try looking at the Aquamist site - http://www.aquamist.co.uk - it's pretty comprehensive and the owner, Richard Lamb is a damn nice guy and always willing to answer any questions you may have.
It's prety easy to fit too - http://www.220gti.co.nz/water%20injection.htm

man!! i just read that thread wildcard, JJJJEEESSSUSSS
that was a long drawn out arguament, and some jester even pulled out a physics gbook

well what i got from it is having WI is good.......its not the solve all thing to do but defiatnely helps and...will defiately make engine run a little bit cooler which i think in a circuit situation, is beneficial indeed similar to an oil cooler.....CORRECTME IF IM WRONG,

how..heres the question, where do i buy the aquamist, and who installs them? POST TURBO not pre turbo, POST TURBO and post intercooler as concluded by that thread and by the aquamist site...

st205 leaving the standard IC in there, that will suffice i guess, cos the ic in that isnt bad at all

I have water injection on my 20V turbo.

It is a circuit car and the last owner run it at close to 30 psi in championship events.
I only run 18 - 20.

From what i understand the more water you can inject the better up till the point that it hydraulics and it must be in a superfine mist.

My car only injects above 10psi and in a race it will use 6 litres of petrol to about 600ml of water. I have not had a play with the system as it's not that easy to adjust. you have to change the jets i think and i only have the one that is in the car.

so you guys running water or water/meth do you pressurise the the water tank or just inject it in with a grunty pump, cos if you are pushing in 30psi of air you need at least 30+ psi of water pressure dont you?

Look at the Aquamist site and you'll see a list of suppliers, inc the NZ one

NZ supplier is here - http://www.waterinjection.co.nz/

Have a read of the site above, says a bit about how the system works.

To get the pressure needed to make the mist fine enough i think it runs at up to 100psi. Hence why you need to buy the expensive aquamist pump.

yeah i read that but i wanna know from guys that have setups and how they are running them cos a few ive seen use a pressurised vessel for the water and some dont. im thinking if you have a pressurised tank you wont need the expensive pump

30psi, sweeet geeesus
thats alot of boost....
well, i would use my fishtank pump but infortunately its not powerful enough
the pumps aquamist sells is a specialised pump for this purpose
it doesnt say on the website how many hours or how much to install

but thast ok ill find out from them by callign them, just thougth someone would know from here

They actually had a piece on one of the high octane vids (i say vids because its not on the dvd's ) where ketz gets Steve Murch to install water/alcohol injection on flyen.
I can't remember if it was HO 2000 or HO 2, all I know its on the old videos but its not on the new dvd's.

Must hit them up about that.

The system looked quite basic with the only real work being part of the inlet drilled and taped for the injector, that and installing that and the bottle close by.

TRDmod - did you look at the link I posted? Fitment of the 1S system is pretty straightforward. Even though the guide I posted is for a Rover, the basics apply to any car. Should only take a few hours to do a decent fitment job. I would also advise putting the car on the dyno too to checke all is okay. I ran too big a jet when I first had it running and actually lost power due to too much water.

Try searching autospeed.co.nz
They've done an article on the aquamist (I think) and a couple on stuff similar...
