I have some updated pics of the finished product with all the hoses attached and vinyl wrapped. I will post them up once I get my car back from being tuned at InnovativeTuning this week.

Mark

Looking forward to seeing them.

Richard,

Can you please explain what you mean by "surge"? What happens during this "surge" and what causes it?

Thanks!

Surge would be air entering the feed line due to the water sloshing around in the tank this would interrupt the injection into the motor causing the fail safe to activate and then deactivate as soon as the level settles.. Having more than one tank should almost eliminate the possibility of air entering the feed line because the water is drawn from the secondary tank and that tank is always full because it is fed by a larger tank where almost all air from the secondary tank is sent to the larger feed tank(spec-C tank).

Mark

Surge in this case is referring the rapid movement of water during hard corninging or abrupt speed changes within the confines of the water tank. This may cause temporary starvation of the water going into the pump. Without water the pump speeds up due to lighter payload. But as soon as the water suuply is restored, the oversped pump puts a pressure spike into the system and line pressure fluctuates violently.

The surge arrestor keeps the line pressure relatively constant by supply a small amount of pressurised water to fill in the surging period.

Ok, great! Thanks for your quick reply. Is anything additional need, except for the tank, fittings and hose? Aquamist is showing a DUAL TANK ADAPTER Part #806 272 List Price: $27.30. I wonder if this is what i would need or is this for something totally off topic? If this is not what we would need, what is a "DUAL TANK ADAPTER"?

The dual tank adaptor will not work for this application.

It consists of a 1/8 BSP Swivelable 6mm tee and a rank adaptor. In your case, you need 1x 6mm to 1/8BSP and a tank adaptor. Need to purchase it separately. You can get the tank and fittings from: http://www.howertonengineering.com. whom holds good stock of tanks and selection of fittings.

So Aquamist has (3) Items listed:

1) Anti Surge Arrestor, 22cc Capacity, Rated at 12 Bars, 1/8" BSP Connection

2) Anti Surge Arrestor, 30cc Capacity, Rated at 12 Bars, 1/8" BSP Connection

3) Anti Surge Arrestor, 100c Capacity, Rated at 12 Bars, 1/8" BSP Connection


Do these items not fix this "surge" issue?

They all do. We have decided to discontinue the 30cc and 100cc. Only concentrated on the 22cc.

I'm almost done with my first HFS-6 install, which is going in an 08 STi.

Here's the car:

http://jamalb.net/gallery/d/5031-2/IMG_0788.JPG

Here's the fancy new HFS-6 control board, which goes in the glove box:

http://jamalb.net/gallery/d/4994-2/IMG_0753.JPG http://jamalb.net/gallery/d/4999-2/IMG_0754.JPG

I suppose I will wrap that wiring up a bit. Moving rearward to the hatch we have this mess going on:

http://jamalb.net/gallery/d/5003-2/IMG_0756.JPG

If I could tig weld this would be done already. Here's the tank and partially completed mounting frame:

http://jamalb.net/gallery/d/5027-2/IMG_0791.JPG

Yeah, it's 4 gallons. Or 15l for you metric system using people.

Moving all that water/meth is the new 160psi pump featuring compression fittings:

http://jamalb.net/gallery/d/5039-2/IMG_0779.JPG http://jamalb.net/gallery/d/5035-2/IMG_0783.JPG

The line and wiring harness to the rear are tucked under the passenger floor along with the fuel lines. There are even convenient extra tabs to mount the line:

http://jamalb.net/gallery/d/5007-2/IMG_0755.JPG

From there the wiring harness travels into the glove box and the pump power wire and tubing go through the main harness grommet into the engine bay with the flow control unit harness. The flow control unit is mounted to the firewall. A 90 degree fitting for the inlet would make this work a lot better.

http://jamalb.net/gallery/d/5015-2/IMG_0782.JPG http://jamalb.net/gallery/d/5019-2/IMG_0764.JPG

Here's the engine bay and ATP 3076 turbo:

http://jamalb.net/gallery/d/5011-2/IMG_0758.JPG http://jamalb.net/gallery/d/5023-2/IMG_0772.JPG

Okay well that's all for now. Once the bracketry is welded up I can get the hatch finished and the car will be tuned tomorrow.

^^^^nice set up JAMAL
 

+1 for HB SPEED shop
http://jamalb.net/gallery/d/5031-2/IMG_0788.JPG

keep us posted and let me know if jon says to do anythinng special for him to tune.
i cant wait to get mine in the mail. and tuned by HB SPEED.

Thank for posting such nice pictures. Great install, especially the water tank and bracket - something very special...

Looking forward to more pictures and tune results.

Well, the car is finished and here are the pictures I took today. I'll start with the pump.

Mounting bracket and pump location:

http://jamalb.net/gallery/d/5047-2/IMG_0793.JPG http://jamalb.net/gallery/d/5051-2/IMG_0799.JPG

And yes, I tapped some M5x0.9 holes so I could just bolt it right down.

Then I got a little crazy with the split loom and spiral wrap to protect the meth line and clean up the wiring:

http://jamalb.net/gallery/d/5055-2/IMG_0802.JPG http://jamalb.net/gallery/d/5059-2/IMG_0800.JPG http://jamalb.net/gallery/d/5063-2/IMG_0805.JPG

Jon welded up the rest of my bracketry so all I had to do was paint it, bolt it in place, strap down the tank, and make the floor fit around it:

http://jamalb.net/gallery/d/5067-2/IMG_0809.JPG http://jamalb.net/gallery/d/5083-2/IMG_0816.JPG
http://jamalb.net/gallery/d/5071-2/IMG_0817.JPG http://jamalb.net/gallery/d/5075-2/IMG_0820.JPG

After testing for leaks, we filled the tank with a 50/50 mix and it went on the dyno:

http://jamalb.net/gallery/d/5080-2/IMG_0821.JPG

Previously the car made 361 whp on 91 octane with 21 pounds of boost. Now with 21 psi it makes 390whp. Going farther on the stock map sensor means there is no boost cut, so we left it there for now. Later on I'm sure we'll put in a new MAP sensor and see what it will really do. This is a stock engine, though, so we're reluctant to push too far. Stupid stock pistons.

Impressions:

I like the HFS-6. A lot.

Wiring up the HFS-5 board never bothered me, and in fact I liked doing it because each installation was custom and all the wires were exactly the right length. With the HFS-6, I have to say the RJ connectors for everything is very nice. Having most of the harnesses pre-set in length worried me a bit, but I ended up with very little extra wiring to deal with. Most of the extra on the trunk harness, and it's just zip-tied together and tucked under the tank. Aside from the tank fabrication, the installation was quick and easy. The fact that I've installed plenty of aquamist kits helped, but I am really impressed to have had no issues whatsoever with the installation of ths brand new product. This one came out of the group buy and must be one of the first to be installed and tuned. I've previously had some issues with the HFS-5, like getting the boost cut to work without throwing a CEL, systems that reset when the lights were turned on, and had a trip-adj pot reversed. All I have to say is this is a really, really great kit. Thanks Richard.

Also, I suppose I could post this up on some Subaru forums.

Nice install pics!

I had a couple questions about the whole install:
1. Are you guys running the meth line in the cabin, under the passenger's side carpet, through the glovebox and the grommet in the firewall?
2. Would it be safer to run the meth line outside? What are the chances of the line to leak one day inside the interior?
3. Question about tank. I don't understand the whole thing about venting the tank. Some say that the cap is vented and some are supposed to vent outside of the car. What are you guys doing about this? Does it need to be vented, meaning have air move in and out of the tank? Do you guys do this with a hose or something?
4. Does having the tank in the trunk make the cabin smell like meth? Does the tank stay airtight?
5. So where are the optimal places to place the spray nozzles? Which direction?

Just getting prepared to install my HFS-6 and I haven't figured out those things...

Thanks for the help,
AK

Tank
 

I also wanted to get some opinions about my tank choice.

http://www.coolingmist.com/products/...rTanklarge.jpg

http://www.coolingmist.com/products/...trunkfront.jpg

http://www.coolingmist.com/products/...Tankimage3.jpg

Would that type of tank be good? Can you guys think of any downsides to using that tank?

As it says on their website "This tank will prime EVERY TIME without fail because the pump and tank are ALWAYS in the same position and only 1 inch of hose is between the pump and tank!"

Let me know what you guys think.

I am not sure how good this tank is regarding sloshing when the tank is half full. I believe it can hold just under 4 quarts (~4000cc). Most of you with the HFS-xx would use two jets consumes about 800cc/min. This tank will allow 5 minutes of full injection. M50:W50 lasts a bit longer, providing you can use every drop of the liquid. In practice, It will be good for 3 minutes.

I will ask jeff (Howerton), whom has used this tank before to post here to make some constructive comments.

I think you should be looking for a larger tank if you are doing a great deal of full throttle pulls. US plastics has a large range of tanks at a very reasonable price.

One of our dealer - howertonengineering.com keeps a very good range of flambleau tanks. They also have stock of brackets that will hold the tank and pump in one neat location - 4-quart tank. but available in 5 & 6 quiart also:

http://www.aquamist.co.uk/HFS6/tank/h7.jpg

The shape of the tank helps to prevent water surging. More pictures at different angles.

http://www.aquamist.co.uk/HFS6/tank/h1.jpg

It is possible to double the capacity by bolting another tank back to back of the first one.

The cross bar is designed for BMW mini installation. Only takes les than 5 minutes to installer. Jeff (Howerton) is very clever at fabricating work as shown below (without top lip):

http://www.aquamist.co.uk/HFS6/tank/m1m.jpg

With top lip and texture coated.

http://www.aquamist.co.uk/HFS6/tank/m13s.jpg

Another great set of pictures. I really think you should post the same onto other forums such as the NASIOC and IWSTi, quite a few people are asking querstions about the HFS-6 install and not many replies.. Please also include the first set of picture also. Not many people has seen the inside of the controller.

Re: Tank
 

We have used those tanks quite a bit in the past and have begun to move away from them. The issue with them is they slosh quite a bit due to the design. If you mount it sideways in the car, the fluid just runs up and down the "U" shape as you accelerate and decel. Likewise, if you mount it front to back, the fluid runs side to side in cornering. I'm not sure how you would baffle it as it is quite hard to get anything through the small filler neck. For the customers that have it, our best recommendation is to keep it half full or so to minimize sucking of air into the system.

Hello HFS-6 freinds :D ,

I have been reading allmost anything the past 2 years about WI and got a pretty good insight how it works and why it would be good on a rotary, but it was thank's to this thread I at last bought a kit, and what a luck, Aquamist was about to launch their new HFS-6 WI and I was in the group buy ! I got the kit 5 days ago and I can only say, it looks promising ;o) I have spoken to Richard a couple of times and he is a very clever guy who knows everything about WI but he still has something to learn about the rotary he says, so he would be very happy if people who actually have installed WI on their rotary would post pic's/comments/bennefits and installation writeups about how people run it in their rotaries ! I have promissed him to give him a lot of feedback about how my installation/experience with the HFS-6 kit goes, right now I am just trying to figure out where to start ! maybe you guys could help me a little ;o)

1. Where is the best place to install the injector noozle ?
2. Should I use 1 or 2 ? (I think I can adjust the flow of the injectors from the controller)
3. I plan to use the washer tank, is it big enough and where would a good place for the pump be ?
4. If better use a trunk tank, any suggestions (pic's/installations)
5. Where to place the controller module/flow module/DDS3 gauge and how to run the wiring ?

Here is the specs for my car:

13B, rebuilt stage 2 modification stock twin turbo, Greddy intercooler, KOYO radiator, Blitz sonic power intake, Downpipe Pettit , Midpipe Pettit, Racing Beat catback, removed air pump, removed secondary valves, Boost Controller Greddy Profec B-Spec 2, Apexi Power FC (already tuned), Apexi Power FC Commander

Low boost is set to 0,6 High boost is set to 0,9 ( Dyno, see picture)

The car will mostly be a dayli driver but will be at trackdays once a while, I know it's a lot of questions, but I really hope you guys will help me, thank you very much.

Does anyone have install pictures on the EVO VIII or IX? Thanks. -Jeremy

I only have pictures of the hsf-1 in my evo 8


but :twisted: I might be installing a hsf-6 this month or next depending on when the guy gets the rest of his parts that will be used with meth injection :wink:

Ok, great, any help will be great as this will be my first install. Not in a big hurry on mine as I am still saving for the new tune that will be required. I am curious to see how guys will be mounting things in the engine compartment and how they will be routing lines from the trunk. I was thinking about routing the hose from the pump along the brake lines underneath the car (I have seen other trunk mount systems this way and it looks very clean) and routing the wires through the passenger compartment along the doors. Also looking at using a one gallon fuel cell which will be vented externally. I am also curious about the best way to vent the fuel cell externally.

I put an AEM kit we had laying around into our evo x for a time attack. Worked out pretty well using the stock 1gal washer tank, which is in the trunk. With two big jets we were close to empty after every session though. I think our evo would be much happier with an HFS-6. I've also put a snow kit in an evo x, but no aquamists in any evos.

Anyway, this is for hfs-6 install pictures. Tomorrow I'll be finishing up an install in an 04 STi. It's a little different than how I usually do them because he has the stock turbo and top mount and we're using the stock IC sprayer tank instead of a spec-c 12l dealie. I could really use a few 0.4mm jets. I'm just going to use one jet before the throttle body but it would be nice to put a smaller one before the IC. I think the pump will also stay at 120psi and I'm using a 0.9mm restrictor. That should work I think.

um

something's not working here

ok nevermind here we go:

Here's another hfs-6 installation:

The car is a stage 2 04 sti. We put on some parts a few weeks ago and tuned it on 91. Last week the car came in for the HFS-6 and I got to work.

Here's my nice shiny table of nice shiny parts:

http://jamalb.net/gallery/d/5148-2/IMG_0028.JPG http://jamalb.net/gallery/d/5156-2/IMG_0030.JPG http://jamalb.net/gallery/d/5240-2/IMG_0036.JPG

Since this car has the stock turbo and is using a fairly small tank, I left the pump at 120psi, went with a single 1mm jet, and put a 0.9mm restrictor in the flow unit:

http://jamalb.net/gallery/d/5152-2/IMG_0029.JPG

So anyway to install these things I tend to tear apart most of the interior:

http://jamalb.net/gallery/d/5124-2/IMG_0022.JPG http://jamalb.net/gallery/d/5128-2/IMG_0023.JPG

http://jamalb.net/gallery/d/5132-2/IMG_0024.JPG http://jamalb.net/gallery/d/5140-2/IMG_0026.JPG

Which left me with this pile of stuff:

http://jamalb.net/gallery/d/5120-2/IMG_0021.JPG


This installation uses the stock STi intercooler spray tank, which is about 1 gallon. I mounted the pump to this flat piece of aluminum, which has tapped holes and bolts right to the chassis:

http://jamalb.net/gallery/d/5216-2/IMG_0059.JPG http://jamalb.net/gallery/d/5232-2/IMG_0065.JPG http://jamalb.net/gallery/d/5224-2/IMG_0063.JPG

I wanted to tuck the pump in behind the tank, but I couldn't come up with a good way to do it and keep the pump inlet low enough to prevent priming issues.

For the level sensor I soldered the aquamist connector to the stock float:

http://jamalb.net/gallery/d/5220-2/IMG_0062.JPG


On GDs, I like to run the meth line up the driver's side with the fuel rails since there are clips to hold it in place:

http://jamalb.net/gallery/d/5184-2/IMG_0045.JPG http://jamalb.net/gallery/d/5188-2/IMG_0046.JPG
http://jamalb.net/gallery/d/5192-2/IMG_0047.JPG http://jamalb.net/gallery/d/5196-2/IMG_0048.JPG


The wiring to the pump and tank goes up the passenger side since I'm putting the control unit in the glove box, and there is also a convenient place to route the wiring.

http://jamalb.net/gallery/d/5172-2/IMG_0040.JPG http://jamalb.net/gallery/d/5176-2/IMG_0042.JPG http://jamalb.net/gallery/d/5180-2/IMG_0044.JPG

It was also nice that a previous owner had cut a hole into his glove box at some point.

http://jamalb.net/gallery/d/5204-2/IMG_0053.JPG

It was not nice that someone had done this to the ECU harness:

http://jamalb.net/gallery/d/5200-2/IMG_0051.JPG

Some soldering and electrical tape fixed things up:

http://jamalb.net/gallery/d/5248-2/IMG_0070.JPG

In the engine bay it was a little tough mounting the flow control unit, but I ended up doing pretty much the same thing as the last time:

http://jamalb.net/gallery/d/5276-2/IMG_0086.JPG http://jamalb.net/gallery/d/5280-2/IMG_0087.JPG

Here's the jet in the intercooler:

http://jamalb.net/gallery/d/5296-2/IMG_0091.JPG http://jamalb.net/gallery/d/5304-2/IMG_0095.JPG

Here's the control unit in the glove box:

http://jamalb.net/gallery/d/5268-2/IMG_0082.JPG

Here's the gauge:

http://jamalb.net/gallery/d/5260-2/IMG_0076.JPG

And hey, everything worked on the first try:

http://jamalb.net/gallery/d/5272-2/IMG_0084.JPG

I put everything back together and cleaned up the trunk area:

http://jamalb.net/gallery/d/5312-2/IMG_0097.JPG

And then it was time for tuning:

http://jamalb.net/gallery/d/5316-2/IMG_0098.JPG

Final numbers were 350 hp and 400 lb-ft at the wheelsl.

Jamal, another impressive install, very nice.

Putting in the 0.9mm jet allows some scaling on the 1mm jet. There are plenty of capacity left in the system, ready for a bigger turbo in the future.

May I put the same links on other site on your behalf?

Nice power increase, Jamal. May I ask what else that STi has done to it?

Good link, very nice improvement. Big turbo next?

I hope so. An externally gated atp 3076 would be a great choice, and I know of a really good place to have it installed and tuned.

Yeah... well, I guess I can start accepting donations...

great pics!!!!!!!!

kit stopped working- don't know why yet. Water level light is dimly illuminated at all times, and comes on fully lit when hitting target boost. No meth flow, but tank is full...

Check the restrictor first. We have had a few block on this piece reported.

I need to either rethink my setup, or find a way to add another tank.
That twin-turbo V6 just eats up my water/meth. :D

Pit, what is your current tank size?
