Hey Guys,<br> I just thought I would let you all know I took the plung and got an Aquamist system from IPD in that GB they are having ($525.60 shipped to your door for the 1s system)<p>I will take pics of the install and let you guys know about any dyno run's I perform afterwards. I hope to install it around labor day or sooner if I can find some good peeps to work with up in Richmond who also have a dyno <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> <p>I am going to run a 30/70 mix of water-methanol mix using the stock reservoir to monitor the fluid lvls. <p>For those who have already installed this (Mistral...looking at you). Where exactly in the piping did you put it? I know it needs to go after the IAT sensor on the intercooler pipe but was curious to see if there were better or worse locations in that area to maximize the effect. Thanks for the help guys.

Re: Aquamist Ordered! (Tarheelvolvo)

Please do a before and after timing. May it be 1/4 mile, gtech, dyno, or anything. As long as you get some numbers and keep the variables ( fuel, temperature, time, weather, tire pressure ) fairly consistent.<p>I thought it would be better if the nozzle was installed before the IAT, but shouldn't hurt it much if it was after.<br>

Re: Aquamist Ordered! (volvoNB)

Already have a baseline done with bone stock. I will try and use the same dyno next time I am in town (ie: wilmington, nc) and do a camparison run with the aquamist and then (hopefully) with an intake as well so you guys can see gains of each item <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0"> <p>Oh, and the reason I was "told" to do it after the IAT is so that the ECU doesnt know its there and compensate accordingly.

Re: Aquamist Ordered! (Tarheelvolvo)

strange as the mist cools the charge and you should get more advance and boost from the ECU. IMO of course.

It's not about dodging the sensor, it's more about being on the cold end of the IC.<p>You'll probably be injecting into the short tube between the IC and the throttle unit. I'd be careful in there, it's not far from the manifold which may not be ideal. Maybe you can get it right on the end cap of the IC, behind the passenger-side foglight.<p>Tom.

Re: Aquamist Ordered! (Tarheelvolvo)

the idea place for insertion of the nozzle is before the IAT sensor, and after the intercooler exit pipe.<p>that way, the ECU knows exactly what the correct IAT temperature is. with a stock map, it probably wont be very adventurous in pushing ignition timing, but it is more useful for a tuner to know.<p>however, we cant do it that way with our car because the IAT sensor is just at the exit of the intercooler core, so i had no choice but to put the nozzle after the IAT sensor.<p>what my fabricator did, was to put a short section of steel piping inside the rubber hose. the then drilled through the hose/ steel pipe to allow the nozzle to be inserted.<p>currently, im running a .5mm nozzle. set to fire at .7 bar. for you, if you are running bone stock, i would recomment a .4mm nozzle, trigger at maybe .4 or .5 bar for starters.<p>the pump itself, he had to seat deep inside the engine bay, near where the transmission is. there is no room on the top side of the engine.<p>if i get a chance i will take a couple of pictures and shw you later.<br>

Re: Aquamist Ordered! (Mistral)

Sounds great, thanks for the info and any pictures would also be very welcome. What are you running right now in terms of ECU upgrade? And does it account for the aquamist kit?<p>I hope to free up some space by maybe moving the battery to the truck and getting a tiny bit better weight dist. and then installing the intake should get rid of that hideous box up front creating plenty o' space. Hopefully that will make the install much easier.

Re: Aquamist Ordered! (tmtalpey)

you know....outta the 50 people who have explained what an aquamist system does...for some reason that one makes the most sense, haha. I mean I "knew" that it helped keep power constant and I "knew" it was good for tuning in the long run, but never really "knew" how. Thanks Tom <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0"><p>Oh, and I will def. be taking pictures of the install when it happens along with (fingers-crossed) an intake and maybe a few other doo dad's like getting my fog lamps back on the car as I liked those things!

Re: Aquamist Ordered! (Mistral)

would it make any sense at all to put in a small bit of piping before the IAT but after the IC and just drill it in there? I am going to have the front end off so it would be very easy to put a small little extension in there is the AM system is really supposed to go before the IAT and not after. TIA

Re: Aquamist Ordered! (Tarheelvolvo)

that was something i considered.. i didnt actually go ahead because my fabricator said it might be a little tricky and then you have the issue of additional hosing and clamping.<br>i knew i was going to get marco to tune for WI anyway, so accurate IAT readings wasnt so imperative for me.<p>sorry tarheel i realise i still need to post my pics.. will take some tonight and post for you.<br>

Re: Aquamist Ordered! (Mistral)

Gotcha Mistral. Looks like I need the "tuner guru" Marco to pay me a visit! Perhaps in my setup I might do it before the IAT in some temp tubing and then could always move it past once I get a tuned ECU to better handle it.<p>Thanks for the pics buddy, look forward to them! <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/embeer.gif" BORDER="0">

Re: Aquamist Ordered! (Tarheelvolvo)

ok here we go.. sorry took these at night. (night time here)<p>first pic - this shows you wehre the fuse is. (very small black box with the blue sticker on it). also, this is where the pump is located. i cant show u the pump, because it is further down about maybe 1.5 feet near where the transmission is... theres really not very much room at the topside of the engine bay to mount the pump.<p><IMG SRC="http://img.photobucket.com/albums/v241/gulug/car03.jpg" BORDER="0"><p>second pic - this shows where i housed the boost regulator - that selects what stage boost you want the pump to trigger.<br><IMG SRC="http://img.photobucket.com/albums/v241/gulug/car02.jpg" BORDER="0"><p>third pic - you can see where i placed the injector - its in between the 2 hose clamps.<br><IMG SRC="http://img.photobucket.com/albums/v241/gulug/car01.jpg" BORDER="0"><p>

Re: Aquamist Ordered! (Tarheelvolvo)

Ok Tarheelvolvo,<p>I feel the heat coming. How is your A Mist going? Looking forward to your update. I'm curious to know if A Mist is viable w/o being tuned for it. The R guys seem to have success with it, but I'm not sure about our cars. I wouldn't want to spend all the time and money installing it to find out the ECU senses something different and cuts power.

Re: Aquamist Ordered! (volvoNB)

Well, due to alot of crap...mainly the install guy bailing on me, me trying to reschedule and him not being found...anywhere <IMG NAME="icon" SRC="http://www.vwvortex.com/zeroforum_graphics/screwy.gif" BORDER="0"> I have postponed the Aquamist until like two weeks from now when a buddy and I are going to attempt it. Looks pretty straightforward from what I gather so I will take plenty of pics and thoughts of it after the install <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">

Cool, pictures are always helpful.<br>Please also keep track of anything unusual or difficult when installing.<br>

MISTRAL: what specific gains are there with your setup? i know ipd has an aquamist setup for sale, but i assumed its for higher boost R models only.

Re: (volvos40t5)

there werent really any gains with a stock set up. <br>as i was preparing my car for marco to come down to tune, i had to get all my bolt ons in place including aquamist.<p>i did go for a dyno when i was purely stock and after the aquamist was installed but did not register any noticeable gain. this was probably due to the fact that my trigger level for aquamist had been set to .6 bar in anticipation of tuning. <p>whilst i do have before and after dynos after tuning, its not really possible to separate out quantitatively what difference the aquamist makes.<p>marco reckons its good for another 10-15hp as he is able to advance the ignition timing more than he would normally do with a non water injected car.<p>of course the aquamist is not just about power, its also good cos it provides a safeguard against detonation.<p>what i can say is that after tuning, there is a VERY perceptible difference that you feel on WOT when the aquamist kicks in (at around 35000-4000 rpm).<p>its almost like a VTEC surge or a second small turbo spooling up and it just keeps the car pulling all the way to redline.<p>
