*** Water/Alky Injection Project ***
Victor: Since the 1s unit arrived over the weekend, I guess I'll stick with the unit and hope for good results. I expect to install it when the rain dies down here in So Cal.
Mine was supposed to be here by now but I havent had a chance to get over to the shop to check on it. I am really anxious to get it installed..
Good luck on your install. Just remember, use the smallest nozzle to make sure you dont lean it out. For an extra margin of safety use a 50/50 mix of water & methanol. Dont run pure water and dont run pure Meth!
P.S-> You know it has to be distilled water right?

Hopefully it will show up in the next couple of days.
I spoke with Richard (owner of Aquamist) and he confirmed it was shipping today. They have been extremely busy and backlogged with work so it took longer than expected to fill the order.
Will let you guys know once I have it in my hands.
Mr. Lamb has been good with answering tech questions.
Tuning the 1s has really been a time consuming effort for the past 2 weeks, I've ordered a boost switch (1-4PSI) via ebay to assist in triggering below the pre-set 3.5-10PSI (I'm not sure if it's a good thing, but worth the experiment). Currently, I'm using the 6mm nozzle plumbed at the intake elbow a few inches away from the throttle body spraying 50/50 water & methanol.
To my surprise, the intake tract is much cooler to the touch as is the plenum. The loud pedal response is much improved and revs smoother, testing during the eves dialed at 3.5PSI, I've seen as much as a 2.5PSI gain (10PSI vs 7.5PSI).
However, it's a bit annoying when I start the car and can hear the ERL as it momentarily activates on. Next up will be to wire an interior LED indicator to the pressure switch as hopefully will let me know when I'm spraying.

I knew you would have fun tuning with the 1s and that's really why I suggested getting the 2D just for the electronics that come with the kit. Any ways, it sounds like you are doing a great job and so far your results seem very positive.
I am dying to get my kit and can't wait to get it installed because I know there will be big improvements on the E55.
Please keep us updated on your progress.. I will do the same as soon as anything changes.
All the best...
I have the parts to install the base kit sitting in my office. We are researching the fabrication of a water tank right now. I am in the process of getting the interior panels taken apart so we can route wires/tubes from the trunk area (where most of the parts will be installed) to the engine compartment.
My business has been very busy these past few weeks so I havent been able to spend as much time on this as I would have liked. It is moving slowly right now.
I should have it installed either this weekend or the one after depending on if I am travelling or not.
Do you have an update on how your water injection project is going?
Your posts have been really nice to read.
thanks
I have routed the wiring in the car and contacted the fabricator for the stainless steel water tank. I am currently trying to locate 30feet of 6mm clear plastic hose to be used for the water supply line.
It's moving along but slowly.
Thanks for your post.
I noticed recently you mentioned this project is still in the future. How is it coming along? Has aquamist given you any help?
Looking at the previous pictures it looked like it would be a cinch to finish. I think that this is a great add and could easily be something that a lot of E55ers would use and could easily be removed for warranty purposes.
Can this forum help with completion?

Believe me, I've been ANXIOUSLY awaiting my kit for a LONG TIME now.. The pics above were of the prototype unit that Richard developed and ended up installing into a different car for testing.
My kit was built.. He was waiting for the shop to fabricate my see-through accumulator tank (the round cylinder tank on the left).
I've left a message and was hoping he would call me today.. It should be ready to ship any day now.. I asked him to send EXPRESS AIR so I get it ASAP..
Will take a few shots of the kit once it arrives and then I will be diving into the install.
I've been working on this project for a long time now.. Had to move real slow and make sure all T's were crossed and I's were dotted.

Lots of money tied up in this project...


It's the only way I can substantiate my claims.
In order to make this work, you have to have the proper electronic controls to maintain the proper fuel/water ratio. If you just get something to spray constant water volume throughout the RPM band it will fail.
The location of the jets and jet sizing is PARAMOUNT.
If the IAT sensor doesn't see the temp drop it wont do anything but lean out the fuel mixture and clean out the carbon deposits in your motor. Make sure the jets are close enough to the IAT sensor but not too close that water will hit the sensor.
In your other thread you mentioned something about flash point.. You have to remember that a proper water jet will MIST water.. Depending on which system you buy, it will have different kind of jets. The cheaper jets will allow too many water droplets and not keep a fine mist like they are supposed to.
If you are misting water into your combustion chamber, it doesnt matter if the IAT is 57C or 80C, when it hits the combustion chamber it will burn and turn into steam.
The whole purpose of the water injection is to get the IAT temps as low as possible to maintain optimal spark advance.




The Aquamist HFS-5 is what I am looking at but Richard has not responded to the last of my emails, so not much I can do until he does...

The thing is the hotter the IAT's the better the system works (within reason), but with 75degC peaking IAT's I dont think its going to make a masive difference.
I intend on spraying ahead of the I/C in the elbow from the S/C. Think this is the hottest point to get the most efficiency from the water injection. I only intend the system to be used for IAT cooling rather than raising octane...and will only inject water.
Actually I am a muppet... IAT's peak to 75deg AFTER the I/C so at the elbow they will be probably be well above 100deg .. so flashing to steam is quite likely at that point and the system should help reduce IAT's quite dramtically.
Think this is most usefull on a VMax run or a long run at WOT. The longer the run the more the system will work as the IAT's will find a plateau... and the hopeless I/C will be able to cope much better....




The limitation is the small I/C core... not much you can do about it.
