I've been looking into different systems, and I figured it might be a good idea to see what everyone's input is. What you use, what you like and what you don't like about the system. So far I've looked into Aquamist and Coolingmist mainly, but I will be researching others. My tuner suggested going with Painless. Rich Farrell suggested going with Aquamist. I have a feeling Howard Coleman would suggest going with FJO...just a hunch hahaha.

I've just started my search but I have a few things I'm looking for...
-a warning about a clogged line, low water, etc.
-something that isn't too hard to install or use
-I don't really want to spend over about $500, maybe $600, but if something is so good I'll consider dropping the money.

OK, I thought I had more stuff decided already haha. The more I read up on it the more I'll be able to decide. But please post up your setup and why you opted for it. Maybe this will help a few others decide too.

And I would have made it a poll but I don't know all the systems out there.

 

I just ordered the Coolingmist trunk mount kit, which is on special right now for $350.

https://www.rx7club.com/classifieds-violations-265/coolingmist-progressive-trunkmount-special-sale-815937/

My reasons:

* Not going for 500hp. Currently at 350 and 400 will likely be as high as I go
* Running water only for detonation control
* SCCA autox doesn't allow alchohol injection, so I don't need the level of control that higher end kits offer
* the kit is priced right
* simple to setup and use

Edit: The 4-120 kit I bought 2 days ago is no longer available for $350.
Probably due to the switch to the new 250psi pump.

 

Bump...

This is getting off to a slow start, haha. I was kinda hoping it could serve as some sort of database so people could just look here and not have to go all over searching. Thanks for your input so far.

 

+1
Im still trying to search for the right kit.

 

Ive yet to install my kit, but FWIW;

All of the sure-flo based systems are similar. you can get most (all?) with a progressive controller or a basic on/off switch. Cooling mist is now selling a 250psi pump, this should help with atomization.

Aquamist uses their own pump, I believe its pump has a lowish flow so if you want to push alot of water you might want to check the spec. Aquamist does have some very nice products tho.

IMO if all your looking at is a bit of knock/detonation protection any cheap/basic kit will work. If you want to do more with it id suggest some research first. I ended up buying coolingmist, the price couldnt be beat.

 

I purchased the Coolingmist kit also. For my current goals (only running water) it is more than adequate. It's still sitting in the box so I can't offer any first hand experience.

 

coolingmist is the way to go.
just received my second kit and their customer service IS MORE THAN GREAT. !!!

 

^ Thanks...
Im really just trying to keep the engine safe... I only plan on running 18 psi max!!!! on average im going to run 14..

 

it sure seems like alot there are alot of AI systems purchased and still in the box.

in the box does not cool your motor.

+1 count another vote for Cooling Mist
Reasons I bought:
1- To control detonation with H2O only
2- Not going over 350rwhp
3- Simple, all in one set up(no manufacturing or needing to buy others things to make it work)
4- Great price
5- Controllers, upgrades and custom parts available for later
6- Easy install
7- Communication/Service/Support is great

 

I know I know! HA. The weather is still crappy so that's my excuse.

 

I ordered a 4-120 trunk mount coolingmist kit with 2x M2 nozzles and will spray pre-turbo and pre-throttle.

I also ordered an aquamist rx-7 injector pwm summing module to get the converted 0-5V signal and input it into the varicool controller and set it to start spraying at a set boost level and follow injector duty for water injection.

dual nozzle HD AI kit for around $500 shipped!

 

i run a fjo solenoid driver off of my pwm out on my haltech. Its nice because you can mess with everythign from 1 piece of software.

for clog detection, buy a small pressure switch and place it just before the injectors. run that to a switch that will jump you to your low boost map when it is activated ie no pressure. low water switch is the same way. i would not buy the cooling mist low level sensor. I could not get the thing to seal. i tried tightening it further and the nut cracked. i endedp welding the hole shut and i jsut look in the tank every now and then to check the level

 

This is what I was looking for guys, thanks for posting!

I think I've decided to go with the FJO kit, once they produce the full kit haha. What I like about their system is that it's fully methanol rated and you can have the water set up to inject based on so many different things...

"This advanced product is engineered to deliver a fine mist that can be precisely metered based on MAP PSI, TPS, RPM, and Fuel injector duty-cycle."

 

Rice, have you read this thread ?

What advantages do you have on your kit, over the Cooling Mist setup.

Personally I like not having pumps (like rices) but don't know about what other advantages (or disadvantages) rice's kit has.

 

I got this email today...

I'm sending you this because you have expressed interest in the new FJO
Water Injection System. Please forward this information to anyone you
know that might like to know this. If they reply to this message I'll add
them to the list and keep them updated.

I spoke with Gerald at FJO this week and he assures me that their #1
priority is getting their Water-Methanol kit out the door. To that end,
he lists the following tasks that must be completed:

-Update and print the manual
-Enter components into system and create price
-Take photographs
-Identify quantity available to manufacture

As soon as he provides me with the pricing (preferrably with the pictures
too) we can move forward. Simultaneously, FJO can be kitting the finished
product. At this point he projects they have materials to do an initial
run of 20-25 kits. Mass production will start after that.

More as I know it. I promise I won't withold any information from this
mailing list so if you don't hear from me it is because there is nothing
new to report.

Oh, I'd add one thing. I leave next Monday for Army Air Assault School
(I'm in the National Guard.) I will be gone for 2 weeks, but will leave
ample instruction with the staff to ensure that everything is handled
seamlessly in my absence.

JKStill and RedBaron. Are you going to just be using the boost activation and the normal controls on the VariCool? Or are you going to use another map source like the 0-5v?

I'm also curious as to if you've installed your tanks yet? Got any pictures? What nozzle size are you going to run?

I love everything about the Coolingmist kit and my goals/motivations are similar to both of yours it sounds like, but my concern with the kit is that the tank might not be big enough. I track my car regularly and I'm not sure if I'm injecting around 300cc/min that the 1.5 gal tank will last 30 minutes?

 

I am running two FJO 700 cc/min injectors controlled by my Wolf V500 ems (2 PWM channels). Fully mapped across RPM and MAP. I have Wolf pulling fuel, adding timing, and allowing the PWM boost controller to operate unhindered based on methanol pressure (I am using FJO's 200 psi pressure sensor). As long as the methanol pressure is greater than 90 psi, the EMS will pull primary fuel, add timing, and not retard my boost. If the pressure falls below 90 psi, fuel is not pulled, timing is not added, but the boost is limited to 15 psi.

I originally setup a map switch like you suggested, but changed that to a actual toggle switch for switching between fuel types.

 

I jumped on the water only, at pre-turbo, bandwagon.

Just received a RiceRacing (Australia), water injection kit.

My reasons /pros:

1. Detonation prevention.
2. simple system
3. Mechanical only system: no pump, or electronics, water flow is proportional to boost pressure
4. 5 micron droplets (fog) are injected pre-turbo: greatest potential for both cooling and knock control when using only water
5. The fog water vapor should not damage the turbo compressor
6. With proper ignition, will allow my 409 whp (current) street port, single turbo (to4r at 14psi) to run at a higher boost setting, and premium fuel, if desired (possibly up to 18psi w/o internal mods?)

cons (so far I just received not yet installed)

1. You must fab/install a 4-5l tank in the engine bay for good response time (not included). It's also difficult to fit a tank in my v-mount ic setup.
2. Expensive: paying for r&d that was completed, & low production volume ($800)
3. Not recommended for alcohol mixtures (consideration for cold climates)

thanks for posting! please get busy and get it installed as the system is of great interest to many.

we will be looking for updates.

^Can you post a link to the thread?



Got this email today and ordered mine!

 

I purchased a cooling mist kit with a 4 - 120 controller.


i would rather use a different controller due to my taste, but if anyone wants it, they can take it for around 100 bucks plus shipping.

 

I guess the post I wanted to reply to is gone but anyway for those that don't know the 4-120psi varicool from coolingmist IS very easy to tune. It is only more difficult do to the large range if using the ***** on the controller.

On the other hand, tune it with a laptop and coolingmist's software and it can be set to trigger as low as 1psi and locks the values in the software so it ignores the position of the *****. There are many other options to tune such as gain and injection curves, trigger modes, min and max pump duty, etc.
