Water injection - first test

[ScuttleRX]

Right its all in and up and running, still a couple of things to neaten up and a small weep on the water filter to sort out, otherwise all ok. Now the interesting bit...

Took it for its first trial, first run got to full boost..then nothing....wheres me power gone, then I remembered the reason why I was getting the little niggling \'youve forgotten something\' feeling, do the intercooler pipes back up Andy...doh!

Trial 2 , worked out a bit better actually cos the time is was sat idling built the air temps up a bit. Cranked it up in 3rd and 4th gear and the inlet temps stayed constant, after coming off boost started to drop rapidly, soon got back down to 30C and stayed there, would get a 2 or 3 degree rise on say a sustained 4th gear run (private road officer!), but again drops down when off boost, a couple of times, mostly in low gear blasts, temp dropped degree or 2 on boost (I think, eyes everywhere). As anyone with a standard intercooler and an air temp meter will know, a sustained wot in 4th will result in temps skyrocketing so 2-3 degrees is not bad at all.

Stopped at the old dears and when I left air temps were up to 66C, found if i just got the boost high enough to bring the pump on, this got the temps down nice and quick.

Now im not sure if the reason the temps come down after boosting may be due to slow response of the air temp sensor, or just the last rememants of water coming out. I do have it facing against the air flow so last pumps of mist may be reaching intercooler giving it a bit of an cooling blast? Not sure really, either way im happy Very very good piece of kit, for under 200 notes you cant go wrong.

Best bit was when I got on a country road, was giving it a good blast round there, not looking at the inlet temps, before I started it was 31, when I finished it was still 31...thats what I was after.

For anyone whos interested to compare temps maybe set-up is standard i/c, filters/straight thru exhaust, pfc.

Forgot to mention car felt really strong all the time, this may just be due to me not having driven it for 3 weeks but it definately felt good

where did you get the kit?,  what else did you have to buy?

[ScuttleRX]

//www.coolingmist.com , had a special for $300 single stage deluxe including clogged nozzle detector, water tank, pretty much everything, only thing extra I had to get was some electrical wire (you do get some, depending on how you install may be enough, i was greedy ), and some tube to run to the boost switch, he has an ebay store aswell with some cheap kits. Hes very handy to talk to, always seems to be there no matter what time you email!

[ScuttleRX]

I think my total was $350 inc shipping, then I had about £40 duty to pay, so more like about £230 all in

what size nozzle did you get with the kit ?
what psi pump are you running ?
Where is your nozzle located ?

[ScuttleRX]

3.9 gph nozzle, this is what he said it would be, havent tested the flow rate, pump is a 100psi one, and ive located the nozzle in about the middle of the intake pipe, with an angled injector that faces the against the flow of the air. I thought i would try this first based on a theory that it might atomise better (imagine spraying hose into wind, spray you get back, as opposed to with it). Think I will try changing the direction so it goes with air flow to see if theres any difference. And also removing angled injector and put it in the standard way spraying across the air flow.

Link to some of my install pics, excuse the mess! will neaten it all up eventually

[ScuttleRX]

forgot to say killed my stereo in the process, think it may have been when i shorted out the cigarette lighter connection when i was looking for an ignition live, anyone happen to know if they are on the same fuse, and which one it is

[sdminus]

Glad it all came together for you.

You need the dual stage kit. It is awesome.

Scott
What PSI have you got your jet coming in at

[ScuttleRX]

I left it as it come which I believe is 10. I\'ve only got boost readings off the apexi so in kg/m3 (or similar!) so just gonna do a quick conversion, its coming on about 0.4 of them. May upgrade to dualies did you use clogged nozzle detectors, i left mine out in the end

[ScuttleRX]

If ive got the unit right (kilogram force/square centimeter) then its coming on at about 6 psi

[sdminus]

No i just fitted the standard kit. Works really well. So well it has caused me a new prob. I smoked the clutch LOL

1GPH at .1bar
3.9GPH at .6 bar

Getting the same results as you but ambiant ish temps

Just come back from a quick blast in sdminus\'s car.

Wow what a machine !!!

Convinced me I need water injection in mine !

Gonna order it next month I reckon.

Scuttlerx - install looks good.

Scott- I can still smell the clutch fumes now lol !!

Sounds good scott, my let down is when sat in traffic, etc really cos of the stock interheater, dont take long to drop, cant wait to do some more testing! Need to give running intercooler-less a try

What clutch you running, is it a standard jobby or have ya uprated it a bit

[ScuttleRX]

I was tempted to try a bit of pre turbo injection, i have got another whole seat recess to fill up nice 150psi and smallish injector to get a really fine mist, dont want a sandbalst effect
