That pump looks pretty good as well, give it a try. As long as its not too big or heavy.
So what are you going to use to control the whole setup?
Because really this whole topic is about the best setup to control the sprayer system, not the pump. Any good high pressure pump will do the job, the one I choose just happened to be small and easy to mount somewhere.

9K, you are right in saying that my setup is more complex, it certainly isn't for someone with very few skills!!!

I have skills. This one gang kept wanting me to join because I'm pretty good with a bow staff.

Scott, I've seen some of the ones you talked about that are $20 shipped, but those are max PSI 40-50 or even 70, however their average working psi is at 20-30. I linked this one coz the description says its pretty consistent ? lol who knows with ebay anyways.

The control could be done several ways, by pressure activated switch, or as Rotaman does it IAT, or maybe just manually.

But I think I'm probably gonna purchase the eBay one and see how long it can last and how good it is.

For $20.00 you can't lose. But it says 100psi (cutoff)

4l/m , 100psi , 12v , $20 ...... Something about that picture doesn't add up

I honestly think a CO2 system will net the best results though .... And CO2 refill is pretty much available anywhere .... and reasonably cheap ?

Edit : Also are you using just straight water, or mixed with isopropyl or something that can evaporate fast ?

You gotta wonder when they start talking about water pressure in Kg ..............

Yeah it's probably a POS pump. But worth it to experiment.

KG/square CM ?

They meant 5.5bar - they say that later in the add.

The shutoff feature isn't something you want BTW

Rotaman

I'm using water, but if you had read my post properly, you would know that it is a mist, ( like a vapour cloud ) and will evaporate very quickly once it is pushed into the intercooler by the incoming air.
My controller uses two thermistors, one for IAT and one on the back of the intercooler. The controller has two adjustments, one for temp and one for fanging.
Thats an Ausy term.

Just pondering here . If you went for a "fang" and then braked quickly , got out then felt the IC . Maybe you be able to tell how far over the spray was reaching ?

If that didn't work - Teams idea with the video camera perhaps ......

I found nice quality brass misting nozzles with 10/24 O ring threads for cheap. I will have my machinist tap and make a spray bar that will mount on the crash bar. I have a local source for high end Parker™ pressure fittings and Nylon tubing that should work fine. I also have a nice Canton Racing 2 quart reservoir that should work fine for the occasional drag strip run.



Deciding on a pump and how I want to control it is next. I think a simple boost activated switch with and optional on/off switch should do the trick for my intended use.

Rotaman

Both methods may work ok to check out how much of the intercooler is getting coverage, and I will have to do some testing.

9K, theres one big problem with using a boost switch and that is it only works when under boost, and unless you know what your IAT is at, then how do you know that your intercooler needs to be cooled down. Also how do you know how long to keep your sprayer on for?
I see you are thinking about using a on/off switch as well, which gives you a little more control.
When you come off a period of boost and the intercooler is under heat soak, how is the intercooler going to get cooled down quickly? Are you going to suddenly remember to switch the spray on?
Anyway just thought I would give you some more things to think about.
Maybe some of you thinking about this should read a bit more about it.
Here is a couple of links

Thanks for the links - good read !

Thinking about the intercooler as a big heat soak def. changes the way you approach the control of the system.

Good points.

logalinipoo

Well if your iat is post intercooler then you could use a voltage activated spray. You could probably make it variable so the hotter it is the more it sprays

Rotaman

For anyone thats interested, here is a couple of links to controllers that would be suited for this setup.

Intercooler Spray Controller

The elabtronics controller is the one I use for controlling the intercooler sprayer. The photo on their website is of the older version of what they make.

Have a look at this controller, its really cheap and works really well. You can find them on ebay for around $20 delivered to your door.

AutoSpeed - $25 Temperature Controller and Display!

I bought a couple of these and have them being used to read temperature at the outlet of the intercooler and termperature at one of my oil coolers.
These little controllers can be used for all sorts of things.

Rotaman, do you think this sensor:

would work with this controller?

I'd like to put the sensor in the charge pipe with a fitting.

Thanks.

9k you're such a noob. Yes, that sensor would work, but why buy them separately? The pair is less than $20 on Amazon.
