I/C spray
 

Know this has probably been asked a few times but I'm not going to be silly with it, i've read a little, I know obviously is keeps the intercooler cool by spraying it, i've got the button located on the right of my steering wheel, and that there can be different modes for it, auto, manual and off, how do i know this is actually doing it's job and what benefits and disadvantages does it have?

Cheers in advance.

Easiest way to see if it's working is to get someone to watch through the scoop when you press the button in manual. It should spray for aporox 3 second burst.
In auto it will be activated by the ACT (Air charge temp) sensor and spray accordingly. To see if this is working, pull the pipe off the nozzle and tuck it under your wiper. Go for a spirited drive in "auto" mode and you will see it occasionally spray when the ACTs get high enough to require it.

Basically it works by spraying the cooling fins with water. Water increases the heat transfer through the intercooler core and allows the intercooler to expell the heat quicker.

Blow on the back of your hand, now wet your hand and blow again. You will feel how much cooler it is when wet due to the increased heat transfer.

Intercooler spray works the same way.

Frayz.

Is yours a jdm? Didn't think uk models had auto mode?

UKs don't have auto mode Chris. Correct.

Dont know what Jacks car is, I haven't looked.

Ah thanks for information frayz, I understand it a lot better now mate,

And yeah i think i must have been reading on a jdm spec or just general forum.

Mine is a type UK. So no it won't have the auto feature, so i'll have to do it manually, i'm guessing overall it cools the intercooler down and makes the car run a bit neater.

Yes, if you're UK spec then you won't have the auto feature. That's JDM only. You will have to add the spray manually. Although to be honest without reading the ACTs it's hard to say how much difference it makes. I used to poke the button on hot days for the placebo effect. Lol.
Would be worth chucking a thermocouple in there just to watch one day though.

If its a UK model then I doubt you'll ever use it. Caning through the gears, flying down the road and then having to take your hand off the wheel to press the button...... Never going to happen is it.

Better off emptying it rather than lugging around 5kg of water for no reason

Pretty much the long and short of it Chris. If we lived in Arizona then maybe worth keeping. But the UK? Forget it.
Better off spending money on heat management under the bonnet. :)

I know i used to use gallons of water in the spec C. glad it had a bloody big tank. :D

Should you put anti freeze or something in the tank?

No. The tank on the uk cars are inside the vehicle. So won't freeze... Not in the UK anyway.

when i fitted my fmic i moved the nozzle to the front bumper and all the water promptly ran out and the ic spray light lit up on the dash.

just trying to work out what valve i need in the pipework to stop this now.

doubt ill use it but like to have everything working in my car.

My tank is puney compared to the Spec-C!

Distilled water only according to the manual

How often do you need to use yours Andy;)

:lol1: oh here we go!!

I'll have you know I used it for the first time on Monday! Admittedly it was purely to see if the pipes were blocked or not but still...:Whatever_ you guys!

One way screen wash valves are available from Halfords on the shelf Dan.

I went to halfords for one the other day, never heard of them! So I went to euro car parts "we don't do small parts"

Bleh.

Halfords have them on the shelf even if the nobheads that work there don't know what you're on about.

I got mine from there.

Alright well i had a lil try last night and it seems as if it's empty or disconnected, judging by frayz reaction don't think I'll bother using it as from the recommendations on here, may be worth just seeing if it is connected still lol

will this do the job??

Part number HWP06

nice one, ill pop down and get one:thumb:

I don't use mine often, but I sometimes use it on hot days or if I've been sitting in traffic for a while as I move off to speed up cooling. Does it make a difference? Don't know, but it makes me feel better. :D

more buttons = better

man fact number 42

hell yeah more buttons ! And it makes a noise too , who cares what it does !

Though i use mine quite alot , does no harm and its not the hardest thing to use.

Cools the charge temp after heat soak from sitting around with no air flow. :thumb: It may be an urban myth but there have been stories of people blowing engines due to caning it straight after sitting in traffic with no charge cooling to offset the raised temps in the I/C. As the temperature of the inlet air increases it not only robs power from the engine but also increases the likely hood of detonation so may not be myth after all.

The marshalls at Santa Pod hate them cos people end up dumping water all over the burnout area. :nono:

I have even seen ice cubes put on top of Top mounts for a 1/4 mile run. :eek:

Do you remember the guy who used a Carbon Dioxide fire extinguisher to spray on his intercooler before running the 1/4?

He was probably just confused by the words Burn out. :rolleyes: ;)

Pete a guy on RTOC uses one on his 5, he has a mate blast it before he runs??
