its been a while since ive been researching into AI, reading thousands of threads, but im wondering which "kit" seems to be best nowadays? Theres generally people on the forums making their own kits as I understand kits even now dont do quite what some people want them to do. I want a kit that will work effectively on the road about 85-90% of the time, and the rest would be for track use. I want most reliable, most efficient Ai system.

For a "ready made" top of the line kit (price difference isnt a deciding factor) which is the best, and why? I cant decide as to which to buy. I'm going 50/50 mix.

Brand choices:

Aquamist: I think they have something like an hsf4 out now thats their best? Ive heard that summer is no longer being sold and the hsf6 is discontinued.

Cooling Mist Stage 3

Snow performance Stage 3

the 3 above are the ones im most familiar with. I know there are more companies that i didnt list.

 

wannamspeed best kit.

 

can i get a link please? also, I think you misspelled the name. What makes it better than the rest?

 

anyone?

 

Mechanical Pre-Turbo Water Injection [PRE Water V2] - $385.00 : Wannaspeed.com!, For all your Go-Fast Needs!

 

thank you. may i ask why this is better than the others, like the ones i posted?

 

I do not have that setup but certainly thought about. What most people like is the simplicity of the kit. First it is pre turbo (some like that), and it doesn't use a pump. Since it is driven off your boost you have less chance of failures.

If you look there are a few threads regarding this exact setup.

 

Rice Racing

 

I agree with Wannaspeed kit. Maybe obvious since I make the kit lol. but the reason I first made the kit was because the mechanically driven setup looked to be very effective and reliable. It has the advantages of adjusting the flow rate based on boost pressure, it does it without any extra modules or potentiometers. The more boost the more water. The only 2 electrical components are a solenoid and boost switch. And it helps the car make gobs and gobs of power reliably on pump fuel, which I think any WI kit has the potential to do. It's crazy stepping on the gas in 3rd and even 4th gear on the highway and you feel the tires break loose when that turbo spools up to 25 psi. So much fun

 

but have those who are running the preturbo kits on the street noticed any turbo issues like fan blade erosion yet? for me the cons outweigh the pros of the preturbo kits if it does ever munch a turbo.

 

If the atomizer is properly sized, it will not affect the blades. Pump driven systems are unable to attain the atomization that the manual kits utilize. The atomizers, though at much lower pressures, use air to create sub 30 micron droplets.

Rice Racing has been developing and selling this design for years with no issues. Lately, he has been running a MAC solenoid driven by a full stand-alone ECU. Of course, this allows the natural progression of the system to be coupled with a full mapable and tuneable auxiliary fuel.

I have put around 2k miles on my system with zero noticeable wear. My atomizer is literally 4" from the compressor spraying dead center. Granted, 2k miles isn't much, but I am confident in the design.

NOTE: I used Wannaspeed's nozzle and solenoid, but I used a custom tank and lines.

 

@XLR8 Im liking the simplicity of these kits! What precautions can be taken if there is a leak or you run out of water/meth?

 

Leaks
The possibility of a leak have been greatly reduced with Teflon push hose and AN fittings. Unlike the vinyl line and pushloc fittings commonly used in water injection system, my system is extremely over built. I have yet to experience a single leak after dozens of air compressor tests and real world driving. I never liked the idea of vinyl line and plastic tanks as the life blood of my engine at 20+ psi. Not to say that Brent has had issues with his kit. In fact, he has been running his setup for over 2 years with no problems. Balljoint also has great success with his kit, breaking the BNR record with 451whp. I will say that I am extremely cautious with snugging down my tank cap. If it were to be cross threaded, the system could loose pressure, and spell disaster for my engine.

Fluid Level
The water level is managed by a simple Gemloc optical fluid sensor. I had a bung welded 1/3 of the way up the tank for my sensor. When meth levels reach this sensor, a nice bright red LED lets me know in the cabin. Ironically, I've never had to use it. A 1 gallon tank lasts more than a full day of driving and a full tank of gas. I typically check my tank before taking it out, and that's about it.

Another great feature of a progressive boost driven system is the nature of increased flow. If my boost controller were to fritz out (no pun) or if I get a boost spike, I am delivering more fuel. With more boost comes more meth, and added safety against detonation. Of course, this isn't to say it would save my engine completely in all conditions, but it would be more beneficial to a fixed system.

 

one simple way to keep an eye on tank pressure would be to install a boost gauge for the tank. then you would know if a line ever came disconnected or something. The lines I use are good up to several hundred psi as they are often used for semi truck air brake systems. As far as fluid level, I just keep an eye on it regularly. Once you use the system for awhile you get an idea of when it's time to fill it. No system is perfect, and it will also come down to whoever installs the kit. But as far as reliability goes, the simplicity already makes it more reliable than most kits just because there is only one moving part, and that's a brass solenoid with viton seals. There is a dozen other things to worry about on the car aside from running out of water or a leak in the WI. The injectors can fail, I've had one fail before, fortunately it was a primary injector and the car would barely run so I knew right away something was amiss. Fuel pump could fail, fuel system could leak, radiator fans could stop working, could get a bad tank of gas. On and on, the nice thing is for the most part the water injection system will add reliability in the case of any of these other things happening, and if you do your best in maintaining the water injection system and the car, you will be as reliable as possible. But all you can do is improve your odds, because something could still happen. A rat could get in your engine bay and chew up the solenoid wiring, or the hose, or just scare you in your car and you run into a pole. lol, but it sure is fun running in the 25 psi area and no matter the risk I couldn't go back to boring 15 psi.

 

I just fitted two of Dudemaaanownsanrx7 kits and they are hands down the best kits on the market and that is not even taking price into consideration. Put price into and you wouldnt even think about it.
I wouldnt deal with Rice Racing if my life depended on it.

 

^ Agreed! Brent's kit and help is the primary reason I'm shredding my 285's in 3rd gear .

Best quote... "know that it works, and get bigger tires"... Priceless....lol

As far as Rice Racing goes, I was quoted $750usd for his kit that didn't include a tank. I chose the obvious route.

 

So,is this kit out of Texas?
I got a bare Varicool kit that I was gonna put on the FC but this Mechanical kit looks good!.
any suggestion??.
anyone got shipped price?..Dudemaaan?..heh!(Ont,Canada,k7a4t1)

 

Yes it's out of Texas, send me an email (Brent at wannaspeed dot com) and i'll get you shipping prices and discuss your setup.

And thank you to everyone for the kind words. I'm glad the kit's are working well and I appreciate the feedback.

 

rx7c, if price was no object would that still be your preferred kit. ?

I want something just to build a buffer we have **** fuel and most summer days its over 100 Fahrenheit (for you yanks)

also can the aem gauge be used on the wanna speed kit ?

http://www.aemelectronics.com/Images...2030-3020M.pdf

 

It might work, depends on if it is just based on water flow or if it takes into account pressure. The mechanical kits flow the same amount as other kits at a much much lower pressure. (under 30 psi instead of 100-200 psi) So if that gauge only cares about how much water passes by then it should work. You could contact their tech support and direct them to the kit or explain how it works and see what they say. Feel free to have them contact me and I will discuss it with them.

edit:
I'm going to send them an email. The information in the link says for 4mm tubing. The kit comes with 1/4" tubing which I think is closer to 6-6.5mm. I will see if I can tubing and fittings for 4mm tubing to make it easier. I'll update once I have information from them.

 

I am going to send them an email to see if they think it will work.

According the the link provided the kit uses 4mm tubing, That size wouldn't work with the other components in the kit, but looking at the picture it looks like it just uses 1/8" or 1/4"NPT plastic pipe with a couple push loc fittings screwed on to the end. If I knew what size they were for sure I could just replace the 4mm push locs with 1/4" push locs. No other changes to the kit would be required. Ill post again when I hear something back from aem.

Edit: Looks like they also sell it with 1/4" fittings instead of the 4mm fittings, so that would plug right into my hose. Just need to find out if it will work correctly.

 

Last post for the night, I keep missing my editing opportunity. The AEM has SAE model that uses the 1/4" push loc fittings so that will work with my hose no problem. The part number is 30-3020 as opposed to the 4mm metric part of 30-3020M. I personally think it should work. I can't see any reason why it wouldn't. The amount of water passing by is the same as any other kit and it has a rangte of either 0-500cc/min or 0-1000cc/min. I think you do a couple base lines so it knows the proper water flow curve. Amazon sells it, could always buy it and if it doesnt work they take pretty much anything back.

 

Funny I only mentioned it as I thought someone was sure to have done this before and didnt because it doesnt work. :P glad I aksed now

I reason I thought it might not work as it might just measure velocity. As with a pumped system pressure is semi constant. (and the area is as well)

But it it does measure pressure and velocity, it would be a handy tool

 

Devils Own claims 20 micron or smaller droplets with their nozzles. Do the low pressure air liquid nozzles perform better? Could an air liquid nozzle be fed by a regulated pump at higher pressure to deliver better atomization than a mechanical setup?
