Im getting tempted to buy a kit for my car, purely to lower intake temps, not to run more power.
Id like to hear people real world experiences with it etc.

Thanks

Have an ERL kit on my S2, worked well but redundant since big intercooler was fitted

I had one in my mk2 RS worked really well.

Im fitting one to my cossie and my green rs aswel, i need it more so ocer here with 40+ in summer

get a better intercooler.

Became redundant when more efficient intercooler fitted. You dont gain Power with WI it just stops you loseing as much as you would when using an inefficient intercooler.
Solve the problem dont mask/fudge the issue.

I have spec r coolers and i noticedit helped.

It depends where you inject but you can gain power with water/meth injection.

Here is my view.

If like me, you dont turn the engine off once its running, unless you have to. After driving in anger then stopping while sitting on the spot the temps will rise in the engine bay. You will no doubt have some heat soak on manifolds and components etc.

At this point if you decided to drive away with high temps the WI system is a good safety fall back. Regardless of how good the intercooler is heat soak will be present.

So my conclusion is that it shouldnt be used as a way to cool the system only used for safety.

Having a pectel monitor on my dash it clearly works and does exactly what i use it for.
My system is split so at the same time of having WI i have a mist system on the front of the intercooler. This also has a manual override, for example if im at the start of drag strip i can mist the cooler to help with cooling just that little more while driving in anger up a drag strip, while suffering from heat soak due to the few runs previous.

It all helps and looks nice while balancing out the weight over the front legs too. (On my car anyway)

Hope that helps. Random pic of tanks.

Jano, where does your WI injector go?
I have a front mount, with no charge air temp issues... Trouble is it blocks airflow to my rad, so i was going to go for a forge double depth intercooler and install WI to work at a certain boost level when inlet temps are above 35c ish.

I have it on mine it's set to come on at 40 degres I think

I'm not even sure if it works now
Since pro alloy done my custom cooler it's never come on

As Jano it's there if I need it

My two pence worth... for road use it's not needed, Jano mentions using it for safety but if your ECU is mapped properly to pull timing and add a little extra fuel (if needed) as MAT increases then there is no problem when stopping and then booting it off again, a few seconds after pulling off the temps will be down to well within acceptable limits and your advance back up.... on the drag strip however every 10th of a second counts so it's a different story
In Rogers case he want's to use it as an alternative to running a FMIC, so might be worth a go, still can't believe your having coolant temp problems mate?! lol

Just take your bonnet of Rog! Job done

Rogeyboy

iTrader: (2)

Im gonna try running an erst bonnet to see if that helps...
But im still cruising at 98-100c even when its 0-3c outside!
Ran 3 coolant flush cycles thru the system, new hg, waterpump etc... Gonna try a new rad and double depth ic with the WI i think. If not then im going zt

St3V3_C

Was OK until this
No.

The problem with WI is it runs out - and you can bet it's when you really need it lol.

I think bigger cooler is the only way forward really. If things are getting hot at a standstill, your fans are not up to the job.

So what charge temperatures are you seeing ?

And anyone who says you cannot gain power with water injection is just plain wrong. That mode of thinking comes from people who think the only purpose of WI is cooling the boosted air.

When in reality the main reason you use water injection is for detonation suppression, but it also helps cool the charge air, which also helps resist detonation. But it's in the chamber where the most work is done.

SO if you're engine is knock limited for whatever reason, then there will always be power to be gained using water injection, or better still a mix of water/methanol.

Or the yanks just favour dumping in shitloads of methanol.

My car runs like this still and I hate it going to try and sort it after the bad weather and I can get my car out. Who mapped your car rogey? is the map ok?

My water would go stagnant before it used the whole tank. Like I say it would only come on rarely so I would never have that issue. Also its fitted with a light and a low level indicator anyway.


For the original thread starter. What water pump do you have. Has it got flat fins or cut out type as this makes a massive difference to water flow. Also fitting small mods like 1400cvh thermostat housing as it has less bends.

SiZT

Pure methanol through a decent injection kit and controlled by an ECU would be my preference. Using meth also has a benefit in that not only does it reduce the likely hood of detonation even further, you can also spray more meth than water

I dont have that time spare while trying my hardest to keep up with massive power cars in my little 1600. Every little helps.

Also I see the mix mentioned regarding methanol which I only use in winter to stop feezing. Dont really see the need to use it for my application.

cossie daz

I've got a wi kit in loft and when I said to my tuner he said to me about bigger inter cooler .
But I wanted it for more safety reason .

On my cossie a few people said spec r cooler but that's nearly £800 where as I feel over kill on my spec so think water injection for me .

My kit never fitted so if you want to make an offer please do

stevieturbo

Water will offer far more detonation resistance than methanol ever will. Water has infinite octane !

The only problem lies in injecting too much water, obviously there will be a downside at some point, hence you add methanol which mostly negates this.
The more water you use, the more precise control you need over flow

Yes you can just inject methanol, and the yanks love that. I think largely because any idiot can just dump in as much as they like and it will still work with no thought required.

But really have to laugh at some....they claim pump gas racing, and pump gas cars. When they're almost injecting more methanol than petrol !!!
Sounds like a lot of them are methanol cars with pump gas injection ! lol

WTF?!

I've had a lot of positive results with pre-compressor water injection. Personally wouldn't do it any other way.

And seeing as some people can't even run full power on their car without needing race fuel, those same people saying 'fit a bigger intercooler' is daft. That's like someone saying to them 'spec your car so it can run full power on pump fuel'.

That's interesting can you explain more. What result have you seen different.

Rogeyboy

iTrader: (2)

Im seeing sub 30c inlet temps with my front mount ic on.
With the standard ic, i was getting 50c+ after a quick burst thru 3rd or 4th gear.
Im looking to run a smaller ic, to allow airflow to the rad but using WI to keep the charge temps around 25-30c.

little bram

What intercooler you thinking of getting mate? have you seen nms coolers
