I'm a new Forester owner, as the 2010 I just bought is my first Subaru overall. I've got to tell you, I've never had any interest in the older body style before, but your car is one of the cleanest looking rides I've seen in a long, long time! Just beautifully well done inside and out! Now I know what I've been missing all this time.

HFS-3 Install #2

I mounted the pump and tank hardware yesterday. The install worked out well!

Photo below shows the windshield washer reservior with the two float switches installed on the side of the tank facing the engine compartment. The float switch on the upper-right is the secondary switch that I installed to illuminate the LED in my gauge cluster when the tank is about half full. The switch on the lower left is the for the failsafe function (reduce boost to wastegate) when the level falls to that point.

The photo below shows the outlet tapping from the tank to the pump. This was installed in the lowest part of the tank, facing the front of the car. There was no room on the back of the tank to install the fitting there.

Photo below shows the pump bracket installed. This is a simple L-bracket from Home Depot (decking hardware) that I drilled and painted black.

This photo show everything installed. The pump is at the same level as the bottom of the tank to avoid any priming issues. The outlet line from the pump to the FAV was run through a piece of 1/4" gas hose to protect it. The custom light bar (made of 1-inch square stock) was perfect for running the line to the other side of the car where the FAV will be located. Notice horn relocation.

The location where the pump is installed is resonably dry, but since the pump must be well-protected from water splashes/drippage, I took a Dremel tool to a plastic food storage container and made a splash shield for the pump. I also sealed off the bumper grille to prevent any water coming in through that.

Next step is to install FAV, remove TMIC to install jet hardware and run all electrical lines into the passenger compartment.

Looking good so far jimmy, good work on the install so far!

Jim, nice work as ususal.

 

[Canonshooter]

Thanks Adam and Brian! I hope to have the install compete and re-tuned in time for WBM, where I am entering my Foz in the car show.

HFS-3 Install #3

This weekend I finished up the under-hood part of the HFS-3 install. This included installing the jet in the TMIC, installing the Fast Acting Valve (FAV), the water lines and the electrical work. All of the wires are now run into the passenger compartment for final hook up next weekend.

These two photos show the jet and hardware installed in the TMIC, on the under side of the outlet to the TB. Since the Perrin has cast aluminum end tanks, the drilling and tapping was very easy with plenty of material to tap. I sleeved the 4mm water injection line with 3/16" fuel hose to protect it - on the second photo you can see it pull down over the barb fitting and secured with a zip tie;

The photo below show the FAV installed on the EBCS bracket. This valve is what regulates the flow of water/meth to the jet. The pump runs at constant speed and the FAV pulses to control the amount of flow - just like a fuel injection system;

While I had the intercooler out I also got around to doing the "4EAT/Big TMIC Dipstick Mod" this weekend.

After I installed the Perrin TMIC, the 4EAT dipstick that used to be just a PITA to get to became impossible to reach - the TMIC was simply too big to get my hand down there any more.

I decided to attach a piece of 1/4" fuel line to the dipstick handle to be able to pull it out. With just the hose, I was able to get it back onto the tube, but could not get the dipstick to seat all of the way. So, I took one of our snow markers (purchased at Home Depot) and cut the top off to make a "pusher." It worked out perfectly - I'm able to reach down and easily seat the dipstick in the tube.

For storage purposes, I stick the pusher in the end of the hose and lay it along the back of the TMIC.

HFS-3 Install #4

Completed the installation this weekend. The system started up and worked perfectly.

Since I am extremely "fussy" about the work I do and had spent way too much time running every wire and line so that it would look as "OEM" as possible, I was relieved that I had made no install errors. All of my electrical connections are "twist and solder" and all wires are run through split-loom and neatly secured. As much as my 56 year old back aches from crawling around under the dashboard, I am pleased with the install.

I have tested the system and adjusted it as much as possible with the jet secured to the windshield under a wiper arm - all appears to be working as expected. The final step will happen on Thursday when I return to EFI Logics to have the car re-tuned.

My sincere thanks to Jeff Howerton for his help with the install! I purchased the system through Jeff and I had plenty of questions. Jeff responds quickly with the needed direction, even over this holiday weekend while I was finishing the install. I must say, I am extremely impressed with the quality of the Aquamist HFS3 system and the level of support provided!

I wish I could say the same for the MadDad boost gauge that I installed concurrently with the Aquamist system. Though the gauge itself looks great, no bracket is supplied to secure the gauge to a bezel (such as the Subtle bezel I used). I used the mounting bracket supplied to hold it in the bezel and some sticky foam to keep it from spinning. What annoyed me the most however is that the gauge worked for all of about 10 minutes when I took the car for a test ride, then the needle froze immediately after making a full-boost run. I sent an email to Rich on Saturday but based on some Internet research, it seems the sender unit crapped out.

I will post my final results, some more photos and new dyno graph next weekend.

Can't wait to see your numbers Jim. You will have the ultimate sleeper!

 

[Canonshooter]

The car has been re-tuned for the Aquamist system. The graph below shows all three of my tunes;

The water/meth injection system and re-tune has made a huge difference in the car. There's far more "real estate" under both the WHP and Torque curves and the car feels much quicker. I will be returning soon to NE Dragway to see if I can break into the 12s.

 

[stan_t]

That is awesome. If E85 doesn't show up around here any time soon, I may go to meth/water injection for more power.

Looking at your (and many other's) dyno graphs it's weird to see how much difference there is in torque numbers between it's peak at 3,200 and readline at 6,500 -- is that just a tuning style? On my graph there is a difference of maybe 40lbs, on yours it looks closer to 120lbs :icon_eek: You are making alot more torque than I am though, but then again I'm tuned for only 14psi -- is your target closer to 19psi?

Looks like a blast.

[Canonshooter]

Stan, the torque spike is due to the torque converter - at least there's one advantage to the 4EAT!
