Hey guy's I have a few Q's about the EVO 3 intercooler water spray on my EVO.

The OEM Nozzle's are like a fan shape spray, They dont seem to have much pressure behind them in order to make a good fine mist (Better cooling)
When it's working it just seems to spray a heap of water onto the core of the intercooler in no real mist (Or pressure) at all.

Is there a way to get a more finer spray or to change the nozzle's or get another pump in line or a bigger pump?
Maybe it could be just my car.....
What is everyone else's spray like?
Thanks.
 
yep mines the same but I removed one of the two sprayer nozzle's and blocked that hose off and it works much better as more pressure for the one jet.
I also removed the spayer pump from the water bottle and it had gunk blocking up the inlet for the water sprayer so working much better still doesn't spray fine mist tho :( :x
 
mine on the evo 2 seems to leak a bit on the nozzle and the washer bottle seems to go empty very fast when i press the button. is it meant to do that or is it because of the leak?
 
I am sure there would be some residue in the lines that would leak :wink:

Mine does and i have to blow it threw after every run down the strip!
 
I an evo water sprayer set up on my car also, but because my intercooler is much larger than the standard one found the sprayers didnt cover enough.

I then replaced the nozzles with ones used for a garden sprinkler system using a 1/2 moon in the centre and 2 x 1/4 circles at each end. I found that they spray is fairly fine and covers the whole intercooler ok. Although it did take a while to get the sprays in the right place to get good coverage... :D

I also fitted a one way valve just before the 1st sprayer nozzle to minimize bleed through once turned off..
 
Ok to bring up an old thread, But I had a look at me mates EVO 9 yesterday & they have a awesome set-up on the intercooler!.
They have 3 nozzel's (Also found from E7 and up)......2 of them spray (sort of trickle) onto the intercooler it-self they are found at the top on the intercooler at each side near the end tanks, and another one at the bottom of the intercooler in the middle spraying a VERY fine fan shape mist up into the air-stream.

Now if I can replace my two nozzles on my E3 to the one that is found on the bottom that has a nice fine fan shaped mist it would work a crap load better, OR even do away with my Factory twin set-up & just run 1 EVO 9 in the middle?
Also they look like to be only 1/4" fittings & I have big 1/2" on my E3, seems like over kill for a water set-up.
Cheers.
 
I got a custom 1 litre surge tank of sorts made up. It's a radiator overflow bottle made from stainless. Has a radiator cap on top, two lines coming out the bottom one of which is blocked (but can be used to drain it).

Runs a small 12v pump inline with the other line to a pair of fine mist garden nozzles in 1/2 arcs. All the piping is rubber and hoseclamped. It runs on a switch currently which I will eventually be rewiring to a temp circuit that checks intake charge temperature.

mines doesnt spray either i think they are all the same what sort of advantage would it provide in all honesty anyhow??

For starters......Far better cooling effect if it's in a fine mist, as aposed to a just dumping water in the core it-self, Atomization is the key to good effiecient cooling. :wink:
Same goes for your fuel injectors, better Atomization......Better burn.

So have you seen your intercooler spray working when you are driving at 100km/h?

Have you cleaned the jets out with a pin?

If you really want a fine mist replace the jets with garden sprinklers which spray in a mist.

i dont think its that that really matters at all. If we were talking about water injection cooling then yes that would be the case.

The main issue here is pressure and coverage, in both of which fields the factory setup is inadequate.......... I think if a more powerful pump could be hooked up, along with these garden sprinkler nozzles, it would make the whole system far more efficient.
 
I ordered a Evo 9 intercooler spray nozzle (Bottom fan/mist nozzle, the other 2 they run dont have as good spray pattern) today from Mitsubishi (part #MI-571768), will put it on my evo in the next few weeks when I get it back from APC.
I will also be running a bigger pump to get the pressure up.
So I'll leave the OEM 2 on the top of the bumper & fit the evo 9 at the bottom in the middle shooting up (as the evo 9)
Will post up how it works & the pic's.
