those pics i ever promised :oops: , this is the angle (of my 300cc injector)
@BellCityDubber: did you tried something out with a CIS pump?

Greetz, Benjamin

No, I havent had the time to mess around and experiment yet... I've been working towards getting my 2nd vehicle on the road, and trying to get boatloads of homework finished.. but if I ever come across some time and some equipment to experiment with, I'll surely let people know...

thanks for the pictures, I really like that spray pattern

Okay, I've finally got some parts that I can play with
I have another intake I can tear apart/open.. I've got another washer resivoir and washer fluid pump, I've got wires (no switch :S )
I've got a bit of tubing.... annnnnnnd..... a NOS fogger....

I'm going to see how well the pump will pressurize and how well the NOS fogger will atomize/fog.

and I'm also toying with the idea of also running an intercooler as well...

I'll be doing some mucking around with this gear this weekend, I'll let people know

let the pump run for 1minit with the nozzle, place the nozzle in a bottle, you can see how much cc/min it flows, if its to much, you got a problem.

Another important factor is that the nozzle is spraying into a pressurized intake. If your washer pump makes 7psi, when the boost goes over 7psi, there will be basically no spraying!

Here is a pic of one of our nozzles showing what a specialized design and more pressure can get you.

I'm a poor starving student, as much as I'd love to get a nozzle like that, and a higher powered pump.... I'm broke, so I'll scavange up whatever parts I can to make something that will do the job.

as for spraying into the intake... I wont be spraying into the pressurized side, I'll be spraying into the turbo intake as per hillfolk'r's configuration...

I have similar parts and pieces so it SHOULD work somewhat similar to his design and perhaps be effective to some degree.

I think for efficiency wise, using the high pressure side would be most beneficial.

this kit seems pretty cheap:

That kit is 200 bucks before shipping.
I have a problem getting 20 bucks
and.... you need a credit card or some method of payment (I hate paypal, I got screwed once)..
sooo... ebay buys are NOT an option.
neither is BUYING a kit.. which is why I'm attempting to BUILD one from scratch, I figure if hillfolk'r can do it... what's stopping me from doing the same?

annnnywho..

I tested the volume of the pump, it delivers about 1&1/3 cup of fluid in 10 seconds... if it's injected into the intake where the popoff valve was, I'm sure the turbo will be able to aid in atomization on top of running it thru a NOS fogger.

i;m gonna try messing with a windex style nozzle and see what happens, and thinking maybe a paint nozzle, and if they don't put out enough, then i'll used more than one...

like an airbrush nozzle? not a bad idea.

All you would really need to make your homebrew water injection system would be the washer pump from a vw, and a good nozzle. (very cheap if you know of a vw just sitting around...)

Go to home depot in their lawn section I think. They sell these little nozzles for people growing stuff (you can either have a jet like spray, or a misting spray. I'd go with misting...)

I think the price is around 2-3 bucks and you could hook it all up quite easily to the washer pump.

Oh I am not trying to convince you to buy a kit - I remember only too well eating noodles out of a bag for months because I bought some car parts. Ah, college.

I was just trying to show what you can acheived with a better design and more pressure - something to shoot for, maybe.

if you ran a metal tank,you could run a boost line to the tank,so the pressure in the bottle is "equal" to the intake,and voila your 7 psi pump squirts no matter what the boost pressure is

why dont you guys just use my setup? it cost like 10 bux,and it works good,i use it as a passing gear on the hiway,lol

i just keep my foot steady,and pull out to pass,i just activate the water injection

ill haveta try and draw a pic from my turbo book on this water injection setup with a pressurized bottle
ya need maybe a check valve and a vent,i cant remember,ill haveta get the book later :wink:

Well, I've done some tests this weekend and used my setup.. the pump is good (1&1/3 cup / 10 sec) I'm using a mk1 washer bottle due to it's size advantage (I dont mind refilling it) my hoses look good and the length is nice for where I am going to mount the bottle.

I tried using my NOS fogger.. but it wasnt as effective as I would have thought. the pattern was right, but little to know atomization/misting

so I'm going to try a few other types of nozzles...
e.g. carb jets, etc
