Need help. I am currently using TMIC and intending to install two jet spray nozzles. Anyone recommendation the best place to place the two jets. If anyone here has similar setup and don't mind showing the photos of your installation. Thank you.

You can install one at the inlet of the FMIC. The smaller one if they are different.

Is anyone on here running pre-compressor with good luck long term?

I've been looking to run a small nozzle in the inlet and one post intercooler (top mount). I have my concerns with droplet size via injection pressure on the system.

Might be best to talk to Airboy about this, I believe he was looking at doing this with his EFR 6758.

So with the weather getting cooler, I decided to do a couple 4th gear pulls last night.

Low and behold, my Aquamist hfs-3 gauge shows the meth flow slowing to 1/3 to 1/4

of what it usually is under wot in 4th gear

(usually shows between 75% and 100%, now getting closer to 25%).

At least I know the failsafes work.

The hfs-3 gauge lights up with both the 'w. injection' and 'water level' lights,

which means there a flow issue.

I can still see the pink boost juice in the tube all the way to the injector, and the

Must be a blockage in the tube/filter, or a pump/injector malfunction.


The aquamist system cut boost, as a result of the reduced flow. (Target boost is set to hold 21 psi)



Here are a couple normal meth pulls I did ealier in the summer, under much
warmer temps...



The slowed meth injection has me scratching my head, as nothing has changed in

the weeks since the normal pulls, except for an oil change, and the hfs-3 system

looks otherwise all good.

Could this be somehow due to the tune/meth settings and the colder weather?
(normal pulls were done around 25c, and screwed up ones from last night at 9c)

Currently running an ETS FMIC w/ SD bung and AEM AIT sensor. This is fed by a BPT 2.5XTR turbo. Wondering if I picked up an HFS-3, where would I install the jets? And, what size would I install? Also, what size bungs would I need? The FMIC is the Titanium unit from ETS, so I need to know specifically for welding purposes.

Peace

size depends on injectors size
best location is right after FMIC outlet

^ So the Injection making contact with the AIT sensor is a good thing?? I would think that would be extremely bad.

Injector size is ID1000's.

I thought the IAT sensor is pre-turbo.

Nope. Turbo inlet has MAF provision removed. AIT bung is now located on bottom side of Throttle Body Feed Charge Pipe (between TiAL BOV and Throttle Body).

is that a 90* bend in the DP right after the turbo?? How does it breath...

Nearly a 90, yes, but it certainly isn't hurting on power.

Back on topic though...

Is there no one else on here that is running an ETS Front Mount Intercooler with Speed Density that has an HFS system in it???

I'd really like to run one of these systems in my car for multiple reasons:
1) It looks like due to my MY STI, COBB will not be supporting it with a FF kit because the ECU has a different setup than the 2005-2007 STI.
2) I like the idea of also aiding in the safe operation of the car.
3) Race gas tune, without the race gas. What's not to like?

There's gotta be more info on this with my setup. Bueller? Bueller?

Scroll down & there's a pic of my setup. You can see the IAT sensor up by the PERRIN sticker.

What is your concern about the injection hitting the sensor? Accuracy of the temp indicated, or longevity of the sensor? Something like that?

^ What a great diagram. Love seeing that. Is there one available for the HSF-4 installed on a 2004 STI ECU?

Yes. As you correctly assumed, my concern is primarily with the longevity of the sensor and the accuracy of the temp readings. Also, with the IAT sensor located near the dead bottom center of the Charge Pipe, I don't want the sensor to be swimming in any un-atomized fluid, introducing corrosion, you know what I mean?

Perhaps it would be better if I were to install the jets directly after the intercooler? Or would I be losing too much of the cooling effect in doing that? What's the best way forward here?

Check out the aquamist forum website, it has a few ecu diagrams, probably has yours.

I haven't heard of meth eating the IAT sensor. (Even if you had to replace every couple of years, a GM open element fast read IAT is about $22.)

Pooling shouldn't be a problem- at full tilt you have a few hundred MPH air going through that tube...

The temp accuracy is good enough. I'd imagine there is some measurable "wet bulb" or whatever temp difference from the water hitting the sensor, but it isn't an issue.

Ideally, you want the jets at the outlet of the FMIC, as far down as you can get them-the further the better. I put mine upstream a bit for ease of installation.

As far as installation.

The jets sit in a jet holder, sealed with a oring. (Be gentle!)

You don't need a bung. The jet holder is tapered pipe thread. Get a new drill bit & tap, think I orderd my jets & bit & tap from Howerton (I bought a used system & needed a few things)

When tapping the charge tubing go very easy- you have a small window between not tapping enough & to much with the thin walled tubing (the whole tapered thing). Check it often so you don't run the tap in to far.

Once you get it good, use some red loctite, or epoxy, to secure/seal the jet holder into the tubing. Just snugg, very easy to strip. Then when installing or removing the jets, use two wrenches so you don't put any stress on the jet holder.

As far as jet sizes. You figure out how much HP you have & how much boost pressure.

Then you figure out how much water the engine needs.

There's a chart/multipliers for that.

Then there's another chart to figure out the jet sizes you need for the calculated flow at your boost pressure & water pump pressure.

It's all really easy when you see the charts.

I'm at 400hp at about 22psi.

I think I have two .8mm. Could be one .8 & one .9. (Just get close, then you can turn up or down your water pump pressure(screw on the bottom) while running the pump for a minute with the jets stuck in a empty water jug. Then measure how much it actually pumped & adjust pump pressure to get exactly the water flow you want. I measured with mason jars-they have the measurements on the side. Close enough...)

The pump from my HFS-5 kit is leaking. Can it be rebuilt? It is leaking between the metal and plastic around the bottom.

Default Injector location in '08-'14 style TMIC

Quick question regarding injector location. I put two 1/8" NTP ports in my AVO TMIC to support a HFS-3 and post TMIC IAT sensor. See below:

http://i.imgur.com/NyF0oUg.jpg
This is looking at the drivers side of the TMIC, throttle to the left side. One port is next to the BOV where the TMIC is sloping down toward the exit. The other is at the beginning of the exit toward the throttle body.

Originally I was going to put the IAT sensor at the exit and the Aquamist nozzle next to the BOV. Would this be acceptable or should I swap them? I'm questioning how much water/meth will flow out the BOV and if the spray pattern will work here.

HFS5 uses Shurflo pumps. Since 2009, we have changed to Aquatec pumps. We have no spares left to repair your pump. The Aquatec pump will work with your system.

what is maximum recommended length of 4mm hose from the FAV to the jet/jets?
manual doesn't provide any recommendations

You need to be sensible about this, You never need to go beyond 2-3 feet. Up to 3 feet is OK. You may experience of some surge at the start of injection if some of the fluid is siphoned out of the hose.

nozzle location question
I need to install 2 jets, I remember Richard saying its best to put them as far from throttle body as possible after the intercooler

however in my case I have my BOV which vents to atmosphere before TB (not shown on the picture, but it sits between the PS pump and alternator, marked red)

therefore I have limited space for jets so I can install them pointing towards each other (yellow)

if, however, this is a very bad idea, I might ditch the BOV and use my integrated BOV in the turbo

Regardless the location of BOV, I still recommend placing the jet at the exit of the intercooler.

When the BOV opens, meth/water will vent out regardless where the BOV position is. If you are concerned, place the BOV at the exit of the IC. Pressurised air will blow off equally well,

are you saying that even if I put BOV before the IC, and jets after the IC - the BOV will force meth/wather backwards through the IC and vent it out? I just don't want to put my engine on fire
