We're starting to work a lot more with WMI so I'm paying much closer attention to details concerning these systems. I've noticed many of the online calculators don't take CFM into the calculation when choosing a nozzle for a specific application. For instance..
Displacement
Max boost
Max RPM
Engine type
Max boost being my main gripe. Stock 1.8t 20 psi 200hp / 3071 1.8t 20 psi 400hp
Surely these will require different nozzles. I know there are A LOT of other factors that come in to play with nozzle selection, but right now looking for a better ballpark than the one I'm playing in now.

I recommend you install a flow sensor so that you can determine how much liquid you are flowing. The Aquamist table was close for me with a pair or 1 mm nozzles but with 0.4 mm nozzles the actual flow was 25% greater than predicted.
I don't know how to go about estimating how much of the spray ends up just wetting the walls of the bipipe.

What is the cost of putting together a DIY WMI system? I've looked at the kits that are available and I feel like I'm resourceful enough to put together my own setup for far less than what others are asking for their WMI systems. I understand I'd probably just need to atleast buy a brain or something to control the flow but as for tubing, nozzles, reservoir... I'm pretty sure I could do it. I build watercooled computers so tube routing and nozzles/fittings and reservoirs is just another day on the job for me  |

I figured I would just ask while I was browsing nef just for the hell of it but it is in fact very possible to compile the necessary components for a reliable kit and then build your own setup. I actually found a fair amount of resources explaining how this is possible. The only vehicle (more accurately the engine) specific parts of the process would be the exact location(s) you choose to integrate your spray nozzle(s) at. http://www.turbomirage.com/water-alcohol-injection-parts-list.html^^kick ass link with detailed info and recommendations regarding what components individuals have had good luck with building WMI setups. And when building watercooled computers you utilize fittings, tubing, pumps, electronic pump controllers and reservoirs so it seems like a similar method would be involved between the two of them  |

You have no idea what you are on about.
It's not only about spraying a jet into the intake, you need PWM control based on fuel injected. You gonna do that on one weekend too?
It's much better to buy a ready made kit from professionals than try to make up some bodge that will fail terribly.
Your thought process of "I built water cooled pc's, so I can make a high quality kit for less" utterly disgusts me. You need a hard kick of reality and not live in lala land.
Buy the Aquamist HFS-3 system, inspect it, appreciate every detail of the engineering that went into it for over a decade and show some respect.

I'm going to assume you've never looked in depth at any of the higher end kits out there. The difficult part is the control. Like prj said, delivering by IDC is the way to go. Not boost pressure, not rpm. I also feel like this thread is going off course. If you want to talk about home made water kits, it might be a better idea to start a separate thread. Could put together a Home Depot shopping list and what not. lol |

Need? I don't know that ''need" is the correct word choice here. You don't "need" PWM control based on fuel injection. Is it optimal? Sure. I've been using WMI which uses the MAF signal to progressively increase injection over a voltage range for years with great result. Is it the best way? No. Does it work? Yes. When I say great results, I mean its an improvement over not using WMI. That's my $.02 |

MAF voltage is perfectly fine, it's the same as IDC.
Your WMI still has an electronic controller, that's my point.
Aquamist also has a dual failsafe with the flow sensor and the level sensor, incl. map switching output for ECU.

A few things.. Firstly, you quoted me saying that I claimed I could make a "high quality kit for less"... The thing with that is that I never said that?... I didn't say, nor do I believe my attempt at assembling/installing a custom WMI kit would turn out anywhere NEAR the quality found in a carefully and professionally crafted product.. I am a perfectionist and I feel I put together quality projects... and even when a project of mine doesn't turn out as good as I hoped, I hit the drawing board and try again... But in this case, I agree with you... to some extent... I agree that I likely couldn't put together the best kit in the world or even one that is as good as whats currently offered on the market... But I mean come on man... Do you know how many times similar posts have been made just like yours but in regards to tuning? I know you've seen something to the effect of this before "do your self a favor and go buy revo before you blow up your engine, leave tuning to the pros" I hope I didn't upset you or anything man... and by all means I ABSOLUTELY didn't mean to make any comments that disgust you  ps: I'm not sure if you may have thought this is what I meant but in the event you did think I meant something along the lines of me thinking I could literally develop and calibrate some sort of management system for the injection I just wanted to clarify that I wasn't going to do anything like that at all... my reference to my experience with watercooling builds was to inform you that I have experience working with PWM controlled pumps such as the Laing DDC or Swiftechs MCP line of pumps... I didn't mean 'I can build a watercooled computer so I can do anything with water and tube...' that would have been ignorance on my part and I don't like ignorance just as much as you don't. I also wanted to say that if for whatever reason, I came off like I was being sassy or a dick or whatever you may have thought from reading my response to your original post, that I wasn't trying to be like that at all... in fact my intent was for you to hopefully read my response and perceive it in its intended angle. Which was basically sort of a buddy chit chat talkin' shop kind of vibe.. lol, I think your a very knowledgeable and good guy around here. So I just wanted to set the record straight one last time and say I meant no wrong. peace! |
