Hey guys, I am a new owner of an 04 evo VIII and am inspecting every part of the car. I got to the intercooler sprayer and tested it with the car in idle...No fluid was discharged while holding down the manual side of the switch. Is this function temperture related or is my sprayer motor not functioning? Im going to say the electical side of it is functioning correctly as I do get the light on my dash display when automatic is selected. thanks in advance

 

Nope it should spray if you hold it down manual idle or not.

Check and see if the bottle/motor assembly is even in the car as many of us tossed them in the trash years ago

 

yea they are worthless dont worry about it haha

 

A couple of years back I took a 400 mile interstate trip on a 100 degree day. The tank was full and at the beginning of the drive I turned the sprayer on. When I got home the tank was empty. I can't say what difference it made but the sprayer was working.

The other day I noticed the sprayer switch was broken. I bought a new one.

 

Why did everyone ditch the IC sprayers?

 

The reservoir for those have a overflow, you can't fill it up all the way to the top, it'll just drip through the hole onto the floor.

Everyone ditched them because it only sprays onto the exterior of the intercooler. No gains really.

 

It seems any gain you got fomthe cooling could also be gottren from the weight removal.

Filled up that thing is heavy.

 

There were a lot of people who used the stock spray reservoir and pump for meth injection as well.

 

True, but that is not using it as an IC sprayer then.

I was speaking solely as an IC sprayer not for other uses. Just spraying the IC is not going to give you more gain than removing the weight of the thing in my opinion. Now using it in the way you describe of course will give you a bigger gain than tossing it out.

 

I completely agree, if they're not using it for meth. It's pretty much useless. I still left mine on the car though, would you happen to know how much the unit weighs? If it's minimal I won't even bother removing it.

 

Sprayer is uselss. I remember when I had my 8 though I was at the track waiting to stage. As I was sitting I hit the intercooler spray and I saw this kid off to the side yell "Oh my god he's spraying NOS, that car is going to be fast!"

 

When it is full I would say a lot in terms of weight reduction. I do not know exactly but I would think ten pounds or greater. The tank holds quite a bit around a gallon if not a bit more.

Add to that the pump and the tank itself and it should be around ten pounds.
I was actually surprised at how heavy it was.


Besides that I used the open area it was at to build a box for my intake filter and some ducting to direct a little more air to it.

 

lulz.

 

Well i use my intercooler sprayer button for Map switching from pump to e85. I got a 03 to have everything sunroof HID sprayer etc but i always planned on using the switch for map swithing saves time wiring etc when you finally get your car tune for both octanes.

 

I would like to see some actual data that the ic sprayer "doesn't" work as in dyno pulls back to back with it on and then with it off. I doubt it would be much but it has to be a little, and as for weight taking it out I wouldn't think would yield much either since I have heard, not proven, but heard that generally 100lbs taken out= -.1 tenth off ur quarter mile time. If that's true ten pounds really doesn't matter that much so I could see it going either way.

I also had a thread about replacing the ic sprayer water with the nitrous express ic sprayer bar and spraying nitrous across the ic instead of water. Anyone think that would yield significant gains or did any testing on that? They claim a turbo civic picked up 50hp from that alone kinda hard to believe, but never seen anything disproving it either. If it would yield significant gains I would run one and wire it into the stock ic sprayer button to work as "oem" where it sprays for 2 seconds every 3 seconds on auto and sprays continuously holding down the manual side. Any thoughts on this?
