two M3s should produce: 3 GPH times two(63 CC/Min*3*2)= 378 CC/Min.
if you are running water that's probably o k.
is you are running alcohol 378 won't make a significant impact.
it depends on what you want to accomplish. reading between the lines of your post.... you have a 500 hp racegas car that you want to duplicate on the street on pump. you will need at least one M15 945 CC/Min on 100% alcohol to do that properly. no knock, etc...
you will also need a progessive controller or a high speed valve system. it needs to be well built as you will be removing base fuel and risking your motor if it doesn't work.
Ai is not, IMO, an area to DIY, unless you are an electrical engineer and have a minor in chemical engineering...
water doesn't happen to be my specialty so i invite any water guys to comment.

Thanks Howard.....
Since I have the pipe already with dual nozels....can I use two M7's? Also, what progressive controller do you recommend and how much are they? I'm having a shop install it all for me, and tune it......I just want to do my homework first to make sure they are recommending the right thing!
I do want to be able to run 20lbs or so off of pump gas so not sure what's the best method for me. I was thinking Denatured Alcohol because it's not corosive and is cheap. What do you think?

i note the thread has not related jet diameter in MMs to flow.
Aquamist has a nice chart re their jets and flow and AQ speaks in terms of MMs. if someone, preferably AQ, might choose to share/copy the chart it would be appreciated.
until then...
for example, a .9MM diam jet is .0354 dia
a .5MM jet is .0197.
refer to C Ludwig's helpful post #23 and you will see the .5MM (.0197) jet equates to the M3 which flows 189 CC/Min at 100 psi.
the .9 MM (.0354) equates to the M5 and flows 316 CC/Min at 100 psi.

Which nozzles provide the finest atomization - fog - without requiring a 3,000 psi pump?
Anything else, besides the SUE18A that Brent has been using? And, about this atomizing nozzle, what is the avg droplet size and distribution? I could not find any info about it.
Thanks,
Sandro

The cooling mist nozzles do not make those.
My objective is to test pre-compressor injection and see how effective it would be in moving the compression toward more isothermal conditions, pre-IC. I have stock twins. Based on theory, I should have better chances by using very small droplets to start with.

spending too much money..

You are going to need the same nozzle that dudeman runs. I've got the 250psi pump and an m10 (770cc) nozzle and it doesn't atomize anywhere near the nozzle of dudeman's. The difference I believe is one is injecting water and air at the same time while the one with a pump is just pumping water at a very high pressure. Good luck though and if you find one, make sure to tell us

Thanks! I will certainly do it.
I would like to find out what droplet size/distribution that nozzle makes... cannot find anything on the Inernet. I may contact the manufacturer directly. I see there are also other companies in Europe that make similar - maybe the same? - nozzle

Dudmans nozzle will do what you want it to do.
BUt it wont run off a pump. It works like a paint gun nozzle, requires both water and AIR to work.
I have noticed no difference between the fine spraying nozzle and the coolingmist nozzle. Not in inlet temps pre-ic etc.
i think your using it for the wrong reason.

That is why I would like to test first to see if WI pre-compressor makes any difference in compressor outlet temperature. Theory says it does, experience on how much I am not so sure.
If you already found out there is no significant difference, that is good to know. If that is the case, could you please tell me a bit more of your WI configuration?
Thanks for the info.

I have not tested difference in temps back to back in the actual compressor housing.
But my IAT's have not changed with water injection as far as i can tell.
Certainly no scientific test and id say give it ago and post back here your results. It will help us all. And that nozzle will work well.
Has it got a 1.4mm tip?

OK thanks.
Don't know about the tip size.
Took the pic from here http://autospeed.com/cms/title_Water...0/article.html
Catalog I found is this http://service.spray.com/web/registe....asp?code=C44M
at page 75 for what appears being this family of nozzles. Does not specify nozzle's physical dimensions.
Keeping searching...

Would injecting pre-turbo cause the blade to rust? I have a dual stage snow performance kit that i haven't installed yet. Where is the best place to mount the two nozzels. Lastly does mounting a nozzel pre-turbo help it spool up quicker?

To keep you posted on my research so far...
I had an exchange of correspondence with Spray. They indicated that under my conditions (air/pressure taken from the twin compressor) I should expect sizes like 80-90 micron
from their atomizing nozzle (SUE18A).
I am now thinking of using the Bete PJ nozzles instead http://www.bete.com/pdfs/BETE_PJ-metric.pdf with a pump.
50 micron at 4 bar

This is a PJ6 nozzle, the smallest. I collected 225 cc in 5 min - using a 150 psi Coolingmist pump. That makes 45 cc/min
quite in agreement with the data sheet http://www.bete.com/pdfs/BETE_PJ-metric.pdf
I am planning on using two (one for each turbo). My objective is to measure the effectiveness of evaporative cooling, if any.
