As the tittle says.here is the one i found in sydney.

>>NOZZLE<<

Here is another but i think it's in melb.

>>NOZZLE2<<

Im actually looking to run a home made kit on the intercooler.Which will run from the washer bottle.

So far on the list i have:-

#atomiser spray nozzle. #check#

#filter.(So no blockages occur) #check#

#hose.

#A T bypass peice with a vavle.(so i can switch between intercooler spray and windscreen washers)

:rant:

yeah they look the part.

It looks like they will cone spray.They were $36.30each with filters.

I was spewing that they diddnt have a cylinder peice to screw over the end of the filter so it could easily be hooked up to my washer bottle lines.Now i have to go and buy reducers so i can run the large hose from the atomiser and reduce it down to the washer bottle size hose.

Heres a pic of the ones i got from TECPRO at castle hill.the one on the left is fully asembled and the latter is with the filter tail dissassembled.

Here are the links to Autospeeds-diy Intelligent Intercooler Water Spray.

part 1

part 2

part 3

part 4

The whole thing with atomisation is so that the water can quickly and effectively cool an object.Because the water dropplets are so minutely small they are evaporated so much more quickly than a dropplet of water would ever be evaporated.effectively cooling the object quicker and much more efficiently also saving water in the process.

I reckon the Autospeed intercooler spray controllers are way overpriced. $240 for a boxed kit (with no pump/nozzles) is a bit much! I decided to design and build my own "smart logic" controller (and have just started selling them for $120) and fits in a box about half the size too. My design and programming covers about 95% of the same functionality as the Autospeed and has the same cooling results. No matter what system you use however, the nozzle choice is crucial to get a good mist spray across the intercooler.

If anyone is interested, check out http://people.aapt.net.au/~mearcat/Kits which has my intercooler spray controller kit, user manual and some test results which I've recently got back from a fellow SAU member CEF11E.

I do not sell nozzles but the TECPRO ones look like a great quality option to provide a nice cone spray mist.

On hot days at the track you notice that the engine wont let you boost 10+ psi for long periods of time at WOT.

The first thing that i noticed with the spray ,was, that i could run 13 psi on the stock turbo without the engine knocklight coming on.

It was on a hot day.so that gave me a good indication that it was working even though it was not the atomiser.The cooler was cool to touch.I was giving it some as well.

The sprayer system could have done with a more high pressure pump to assist in it's spraying as well imo.The stocker is just under par when it comes to the pressure required to get good atomisation out of the nozzel.

The whole reason that i diddnt reply to the thread that i started was because on the day of me fitting the sprayer to the bar at the track,i found out ,while pre testing, that the sprayer nozzel was blocked..I had a spare but had left it at home.It was working fine the day before.

So on the day all i did was crimp the end of a hose and faced it down at and towards the intercooler from the mount i had origionally made up for the nozzel.It wasted water like all hell but somthing was better than nothing.

Some of the things that you have to remember are that you "need" a decent brass atomiser sprayer nozzel with filter cartidge and male barbed adapter tail,so you can readily fit the hose on and off, and also a one way valve,just like the ones in your window washer lines so water wont just drip out while not in use,put in line between the pump and the sprayer..It would also be ideal to upgrade the pump.Somthing like the cheapo option that autospeed suggests be used "that is" the vt washer bottle pump.It has slightly more pressure than the nissan item.i know because i bought a second hand one ,it was trialed,but diddnt fit it because i wanted to use the stock bottle that its connected to it and diddnt buy it :P and i diddnt feel like hacking away at the stocker bottle to only use it a few times a year if you get my drift.But still this system will not produce massive atomisation mist.like the ones you see in the tecpro/autospeed pictures.if you want that then go out and buy a high pressure aftermarket pump..

The pumps for the washer bottles are gravity fed.Make sure u get the filter for the vt pump as well.Im pretty sure that they have them stock just check

Sorry - I don't mean to hijack the thread. The controller does come boxed, but I forgot that I haven't put any photos on the web page or in the manual. I will do this in the next day or two and update both page & manual. And yes it has lights to show Power On, when the two configurable items are tripped (AFM voltage & intercooler core temp) as well as when the pump is on (whether tripped by the controller or via the manual override switch)

I found that it didnt more produce "feelable" power but it did allow me to run the same ammount of boost all day long.Which i guess in turn allowed me to keep the consistency of power there.In winter though the story might be a bit different.

The VT pump doesnt fit the stock washer bottle.Though you could if you wanted find some room for it all to fit and drill a small hole and silicon in place the pump.There would be no leaks.Though i like the whole separate washer bottle idea myself..On the stock setup it'd be a good idea to run the rear washer pump for the sprayer pump because it rarely gets used.

Also id look into going for a cold air duct.it all helps.

The other problem with running that ammount of boost on a hot summers day is the engine temps.It's best if you had an aftermarket radiator and a gauge to keep a check.Though i only had the stocker radiator but had an accurate gauge to keep check on the temps.Plus i run an oil cooler.

I was told that just jap are selling aftermarket radiators for skylines at arround the $300 mark.Better than pwr prices.And if you want a permanent solution to engine temp problems thats the way to go.

I found the same when I fitted my FMIC. No noticable power gain but intake temperatures didn't spike as much after multiple runs. Once the intercooler water spray was fitted, the intake temps dropped and remained much more stable allowing for (as Trust33 said) a more consistent power level.

Oh and btw - the intercooler spray user manual has been updated now with pic of LEDs in the controller box http://people.aapt.net.au/~mearcat/Kits

If there is no noticable power gain then then this is more of a support mod?

Also, as you all know our cars run better in cool weather as opposed to hot weather. Will this mod make our cars run in hot weather as it does in colder weather?

And finally, have there not been tests done whereby water spray, NOS sprays etc increase power on the dyno? hence shouldnt this increase power?

i just picked up an atomizer nozzle today from a place in morrabin vic for 4bucks each. simple unit not as advanced as yours with filters and all but seems to atomise better than my old bunnings nozzles...ha

anyways, im having the same issue with the water pump not producing enough pressure too atomise propperly. how much was the vt pump? anybody else know of any other pumps that flow better than the stock ones?

thanks

just posting an answer to a question. :yes: to help out others.

*use same size hose as what the outlet of the pump allows.no bigger.bigger and you will loose pressure especially over distances.

*use a 1 way valve in the hose to stop leaks when off pressure.thus saving shitloads of you water.you have a 1 way valve in your front window washer line.you will see it.it has a white stripe.

*for a temporary mount.buy some cheap bunnings aluminium.make sure you face it so that the hot side of the intercooler gets the bulk of the spray.and allow fro wind hitting the atomised air at high speed.you dont want the intercooler only getting half of the spray.

-i went here to buy my nozzel.

http://www.tecpro.com.au/?gclid=COiHlLjIqY4CFQXXXgodNDstVw .they are in sydney.

-i suggest that you get the same setup as what these guys have.tried and tested.

http://www.autospeed.com/cgi-bin/browse.cg...=888800068& .Great article btw on the intercooler water spray.

-and found a place that allows you to shop through their online catalouge of atomiser spray nozzels.you get to chose what size nozzel you want through the different pressures,spray patttenrn and flow rate.very good.because you can then take it to say "techpro" who could do an equvillent for you.and if you are going to do that then your best bet is to photocopy the picture of it allong with its specifics so that they have a real world example of what it is exactly that you are looking for.

http://services.bete.com/scripts/wsisa.dll/select/select.r

My nozzel never really had great sucess due to low pressure.see if you can find one that allows you to have a decent sized spray pattern (enuf to spray the face of your intercooler) allong with a low pressure operation so your pump stock can operate it with more sucess than every1 seems to have.

could you rig the 2x pumps to work in unisen to operate efficiently .and provide a little bit more presure?

    • Pretty much what you'd expect at that power level. Hypergear turbo, long list of supporting mods, full Haltech catalogue, etc.  I'd say this goes for most drivers, suspension is still a dark art for most people. And it's really hard to convince someone how much better their setup could be...  
    • They are what I will be installing. 640s for me.
    • Hmm... From my experience you get about 0.25° camber change per mm of RUCA length change. So, to correct from -2.5 up to less than -1° (or, more than -1° if you look at the world as a mathematician does) then you'd be making 6-8mm of length change on the RUCA. From a stock length of 308mm, that's 2-2.5% difference in RUCA length. My RUCAs are currently very close to stock length - certainly only 2-3mm different from stock. I had to adjust my tension arms by 6mm to minimise the bump steer. That's 6mm out of 210, which is 2.8%. That's a 2.8% change on those, compared to a <1% change on the RUCAs. So the stock geometry already has worse bump steer than is possible - you can improve it even if you don't change the RUCA length. If you lengthen the RUCAs at all, then you will definitely be adding bump steer. Again, with my car, I recently had an unpleasant amount of bump steer, stemming from a number of things that happened one after another without me having an opportunity to correct for them. I only had to change the tension arm lengths by 1mm to minimise the resulting bump steer. (Granted, I also had to dial out a lot of extra toe-in in the rear, and excessive rear toe-in will make bump steer behaviour worse). Relatively tiny little adjustments having been made - the car is now completely different. Was horrifying how much it wanted to steer from the rear on any significant single wheel bump/dip. And it was even bad on expansion joints on long sweepers on freeway entry/exits, which are notionally hitting both rear wheels at the same time. My point is, the crappy Nissan multilink is quite sensitive to these things (unlike the very nice Toyota suspension!). And I think 99.75% of Skyline owners are blissfully ignorant of what they are driving around on. Sadly, it is a non-trivial exercise to set up to measure and correct bump steer. I am happy to show my rig, which involves nasty chunks of wood bolted to the hub, mirrors, lasers, graph paper targets and other horrors. Just in case anyone wants to see how it is done. I'll just have to set it up to take the photos.
    • What do you have in that bad boy ? Ill go with the 725cc since I'll be going with Nistune ( would definitely like more engine protection but Haltech is too far out of reach at the moment... plus, Ill probably have a pretty safe tune as its a daily, not gonna be chasing peak power 24/7 ahahah ). Are Xspurt a safe choice?  Pete's great. He didnt mention anything about traction arm length so I reckon it may be good. When I get some new wheels/tire later down the road I'll ask him about it and get his opinion on em. I heard from Gary that you've got the bilsteins too, are you running the sway bars too? and what other suspension goodies do you have installed or would recommend?
