Water / Meth injection details

[URquattroGus]

What are the downsides of meth? Reduced oil life and corrosion??

Can you run just water injection and not a water/meth mix?

Also, presumably this is not a DIY thing to fit? Has anyone fitted theirs or paid to have a system fitted?

Head porting sounds maybe more sensible.... Maybe betterr spool/efficiency lower down the range and more peak bhp, maybe another 30bhp clutching at a guess?

Water injection is very easy to fit. Mine has a .5 jet on the exit of the second intercooler, my boost controller controls it. Mine isn't mapped for it for fear of it packing up. I just have it for some top end protection above 1.1bar.

Works a treat...

Yeah I have it fitted to mine also, using a 0.5 or 0.6 jet triggered on boost, but not mapped in at moment. Would consider changing it to a mapped version but need a high speed solenoid valve for it too, but its mainly for some top end protection too

The stock IC on AAN flows well enough for about 480hp, before it starts causing serious problems, I can't imagine it being much worse on the ABY.

Prj,

Is the above comment correct that the little postage stamp of a stock intercooler on the side of a urS6 is sufficient until one reaches 480bhp, or have I miss understood your comment ?

Thanks.

If you are very worried, just run denatured ethanol, will be just as effective as methanol.

Yes, definitely.

This can be very much DIY, if you are even remotely handy with spanners.

Don't know your map, so can't comment

I use the Aquamist HFS-3 system, which has an actual flow sensor inside the meth line.
So if anything packs up, that flow sensor sends a signal to the ECU and BEFORE the charge without meth hits the cylinders, the ECU switched boost, fuel and ignition maps to meth-free operation.
So it is 100% safe.

Also, I run dual 1.0mm

Flow wise, yes. And the cooling does not matter if you run meth injection, since that is more efficient than if your entire car was made of intercooler.

I did an article for Audi driver on fitting water inj. Can e-mail to anyone interested

Would be good, you should be able to attach virtualy anything to the forum, and I think this information and line of talk needs it's own thread not in this gentlemans project thread

Tried uploading the PDF but as previous attempts in the past, comes back as upload failed, so back to anyone interested, PM me an e-mail address for article.

Here is the pdf on the water injection system.

I've been looking at AEM water injection as I like their failsafe http://www.aemelectronics.com/water-...afe-device-69/

Although that can be integrated in any water injection kit

Thanks for getting PDF up , Mine has had a slight change this SORN as the units 'fault' O/P also triggers the standard map....

[Greg_S]

can you still purcahse the FiA2 and the HighSpeed solenoid valves from aquamist?

[Greg_S]

Been having a bit of a think about this the last couple of days, when I get a few other bits sorted on mine I was toying with the idea of building my own PWM amplifier off one of the injectors to drive another injector that I can use to drive the water injection in conjunction with other pressure sensors.

Do you reckon a standard fuel injector would be ok to use with water alone?

Depends if injector seals etc are compatable with Methanol.
Most Aquamist stuff is still available, I use JBS below:

Quite good forum with lot's of infoa about water/meth injection, at least about Aquamist systems. http://www.aquamist.co.uk/vbulletin/index.php
