Default Navybluesubaru's water injection install: Part 2

OK... After spending the last few days working on the UTEC map, I'm simply floored at what this thing is doing!

Couple of items to note:

A: I've basically shut off all knock correction. The ecutek would only get up to about 18 degrees advance at redline even with the UTEC knock corrections at 1!! Of course... this isn't something your average person deals with.. that's just the price I pay with the internals in the vehicle.

B: That being said, I'm running a static timing map above 4000 RPM from 17 PSI on.

----

Now, that being said, I'm running 22-23 PSI and 25-27 degrees advance on 93 octane gas! That's with fueling at 11.3-4:1.

Anyone who's been up at those tuned boost levels know exactly what I'm talking about here....

Those are timing and boost levels I'd typically run on 104 octane fuel.. on 93 octane

I'm using the 5GPH nozzle, which is a little smaller then aquamists largest nozzle.

EGT's are around 1500F at 6800 RPM in 3rd (115MPH). I'm using about 80% concentration of water and -20F methyl alcohol washer fluid. Reason it's not 100% washer is from left over water from testing the system.

I can't wait to see what this thing is like with 100 octane and water injection!

But for now, I'm satisfied! It's raining now, so I'll finish the photo shoot for my write up later on tonight, or tommorow.

For $250 I clearly concur on the investment. But if everyone's jumping on the supply demand bandwagon and jacking up the price by $100, like on WRXTUNER, then it's clearly not worth it.. in light of the fact that it took about $50-70 in added parts to install the system to >MY< level of refinement and OEM finish.

More later...

Default Dyno info

Dyno Test: j2
=============

Maximum Wheel Power: 335.0 BHP @ 5903 RPM
Maximum Wheel Torque: 317.2 LbFt @ 5088 RPM
Power to weight ratio: 197.0 BHP per ton

Terminal velocity due to power: 190.1 mph

In Gear Acceleration:
40 - 60mph = 2.7 seconds
50 - 70mph = 2.3 seconds
60 - 80mph = 2.2 seconds



By comparison... this is the original 93 oct tune..

287 lb/ft @ 4300 RPM | 275 WHP @ 5800 RPM | 93OCT


All by adding a little bit of water and alcohol to the mix

The first one was done with Ecutek's road dyno function, the second was done using my actual "Road Dyno". The ecutek typically has read lower then my "Road Dyno" tool. For comparison sake... my 275 on a slightly warmer day was around 260 using the ecutek function. So for me to be showing almost 340WHP via Ecutek, I consider that "conservative".

I also did a second run with the ecutek and it showed 341... but for the sake of being "conservative", I'm only showing the lower of the two.

dang, one of these days I need to take out my aquamist kit that has been in the garage for 2 months now collecting dust :/ Laziness is amazing sometimes.

At the price of $350 I don't personally seeing it survive since aquamist kits that come 100% complete with pressure switch, etc can be had for about $400. I always like to see implementing new versions though, so hats off to navy guy.

WI alone Doesnt make the gains.. It is the ability to tune more aggressivly with the WI that makes the gains.

Nick and I will be offering a group buy for impreza.net members here really soon for $275. The increase in price is reflected by the increase in quality of various parts, packaging and such. We have sourced the pressure switch and will be offering it at a much lower cost than i've ever managed to find it for sale at retail prices. If anybody has any questions, please feel free to chime in!

So $275 GB will be a full kit not needing anything?

pretty much...now if you plan on mounting the pump in the trunk or something wild like that then you will need to buy more hose....but the kit comes with everything you will need to mount it near the battery. The system is very flexible so you can really do with it what you want, as long as you are willing to buy extra hose if you go wild with it.

So this is intended to reside where the battery currently resides right? That means I have to relocate either the pump or the battery. I think I may have to put the pump in the rear of the car, since I'm gonna mount a reservoir there too. This kit does not have a reservoir with it correct?

can you provide a list of all the parts included in the setup?

btw, for a kit like this, is the WI mappable to the fuel injectors or something? or is it just regulated by manifold pressure? (like the 1s aquamist system)

Jeff, I sent the money order to you over a week and a half ago, and have not heard anything from you. I have given you the info on my setup already. What are my prospects on receiving the kit soon?

You mount the pump infront of the battery. The kit does not come with a resavoir as of yet. I have the kit utilize the stock washer fluid tank. Thats how i have mine setup and it works just fine. If you plan on putting the system in the trunk you will need extra hose that we can provide if you mention that you need it, we will just charge you a few dollars more, no biggie. Also, we can provide pressure switches for those who need one. I will try to get nick to post the group buy today in the vendor group buy section, then i'll post the link to it here!

Our kit includes everything you see in the picture at www.wrxtuner.com

Our latest upgrade to the kit includes the utilization of a Copper-Nickel nozzle, which provides superior resistance to corrosion, similar to that of stainless steel. These are standard now in every kit.

Default 100 octane update

Not one to leave good enough alone... I started working on my 100 octane map yesterday... OMG...

Let's just say this.... 12.3:1 at redline, 32 degrees advance at redline at 21-22 PSI at redline.

If the steering wheel is not perfectly straight it'll start torquing the car around. Also even at partial throttle the car starts breaking the tires loose (just a little water on the roads yesterday).

Finally, I could FEEL the heat through the firewall and floorboards from the engine radiator. Here's where the PWR is paying for itself. I ACTUALLY heated up the NPG+ so much after about 4 back to back 3rd gear pulls that I expanded it to the point that it reached the top of the overflow hehe.

Finally, I've actually hit the high stall point on the converter with the amount of input torque.

When the car shifts into third it basically drops RPM to around 4800 and starts to climb from there... Here it shifts to 4800 then it shoots up to around 5300 in 3rd and the MPH climb about 15-20 MPH before the driveline starts to match the torque converter RPM. CVT comes to mind hehe... That or I'm superbly slipping the clutches (my first paranoid thought), but judging that the tranny temps are all of 140's and I don't smell any burnt clutch material at all (just burning coolant from the overflow) and the car drives fine other wise... I'll discount it. But I've now become aware of the levels of torque coming out of the car, and realize that this map is defineately something of a special occasion until I can "properly" have the trans built up by Level 10 (hopefully over the winter, but we'll see).

Judging by the "substantial" increases in performance, and using the 335 from before as a basis, I'd estimate WHP conservatively in the 360's right now (by ECUTEK standards). But I could very well be WAAAAAAAY off since my butt dyno is still tingling and hasn't formed an unbiased opinion yet hehe.

Hey jorge, that sounds awesome! On some occasions i'll get that feeling of torque steer, but not all the time. Mainly just from a roll in 2nd or 1st. The front will pull so hard that it pulls to one side or the other...its hard though to do that seeing as its awd and has equal-length half-axles. Anyhow i too have broken loose in 2nd from a roll when the roads are wet, its scary and awesome at the same time!

Over the weekend me and jorge installed my WI kit. All I have to say is WOW! We went for a test ride after it was all done and tryed my 100 octane map just for kicks. Perfect! No knock and the car pulls like a train. Although we did have a slight leak, the kit install went well. I had to buy some parts for mcmaster carr but that was because we mounted the pump and tank in the trunk. Ill post some pics and the part #s soon. And like jorge said I cant wait for the 100 and WI map!!!!

I have a question how long will the washer fluid container last, what I'm asking is how much water does it generally consume? Like will I only get a couple runs at the track and have to refill it?

I have contacted Nick at wrxtuner.com and the groupbuy should be posted sometime today...im going to be checking for it periodically throughout the day.


BoostGeek - The resavoir lasted me typically 2 tanks of fuel per one tank of fluid. It depends on when you have it come on and how big your nozzle is. Turning on at 7psi with a 5gph nozzle those were my results. I have it come on at 10psi now so it should last even longer.

Heres a note for all those doing the install:

Mount the Solenoid AS CLOSE AS POSSIBLE to the nozzle. I have recently hooked up an additional 1gph nozzle and redid my hosing. Previously, the solenoid was right next to the nozzle, near the bov. Now its back near the firewall, going to a "t" which then goes to the nozzle on the ic and the other nozzle in the y hose. Since i have done this, my water consumption has nearly quadrupled. Im suspecting that water is being drained from the hoses while the system is off. I have checked for leaks several times and found none. So the moral of the story is MOUNT THE SOLENOID RIGHT NEXT TO THE NOZZLE!!! Its ok to have about a foot of hose if you must, but i have like 3 or 4, because i need enough hose going to the y pipe that i can remove the ic with the hose still attached, otherwise i could never install/uninstall the system.
