Cooling Mist CMGS install
Cooling Mist CMGS install
I have only seen one other setup pictured on here this way and the pump placement was a little different so I decided I would share what I did.
I purchased the Coolingmist CMGS controller kit with the 250psi pump, flow sensor and low level sensor. I wanted the added safety of the failsafe feature and easy, simple tune-ability of the system. I inject based only off of boost beginning at 7psi and at 100% injection at 12psi. I am currently injecting 0degree F washer fluid which should be around 25-30% methanol. This system was installed only as added engine happiness as the car was tuned for 93octane fuel only.
On to the pics:
Pump installed in the spare tire well secured to the back wall. It would have been a cleaner install if I had two 90 degree fittings for input/output and I will most likely pic some up later, but it functions perfectly as is.
Since my car is a touring model I have the rear wiper fluid tank that has yet to be used since I purchased the car many years ago. So I decided to put it to use as you can see in the pic above. It really is a good tank design because all fluid drains into a very small area to maximize the amount of fluid in the tank. The area is large enough to install the outlet fitting to the pump as well as the low level sensor.
To get the sensor in you must cut a hole in the top of the tank, cut your mounting hole in the bottom of the tank and then plug the hole in the top. I just drilled a 1" hole and then picked up a plug at lowes. I also used sealant to seal the bottom of the tank for good measure. I have been running this for one month and have zero leaks. (Oh, you also need to seal the top plug or it will leak when you fill the tank.)
The feed line runs out of the spare tire well, around the gas tank, and then follows the fuel hardlines up to the firewall. This I really liked for protecting the line. At the firewall my flow sensor is installed and secured (sorry no pics) and then the line proceeds upward to my M10 nozzle located in the bottom of my GReddy elbow. I have an additional M7 nozzle I am thinking of installing but have to way to look at EGT's yet to see if it is needed.
Final install with carpet and plastic installed:
The tank works great for just driving around town with decent amounts of boosting the car. BUT I am afraid it is too small for a track day. It holds ~0.25-0.3 gal. I may be able to modify it in some way to connect another tank. One really nice feature is how easy it is to fill the tank and how stock everything looks.
The controller is mounted on the dash where it is easy to read and adjust. When the low level sensor is tripped, or any of my flow criteria (overflow for a leak or low flow for a blockage) is met the controller cuts power to my boost controller lowering boost to wastegate pressure.
My only real complaints on the system are the controller face is poorly designed and light from the led's to illuminate the face shine through the face at night, not just through where light is intended to shine (words and logos). My second complaint is the controller displays boost (no vac) and has a very delayed response to actual boost pressure. This does not really bother me too much b/c I have my boost controller right on the steering column. But anyone wanting to use the controller as a boost gauge should think twice.

It's a really nice a clean install, I would hope to do something along these lines in the future. Please update the thread if you do end up modifying the tank, I would be really interested to see. After having the setup for a few weeks now, do you find the stock wiper tank adequate?
I wonder how much one would be looking at to get a larger tank fabricated...anyway, good ideas here, thanks.

You said: "BUT I am afraid it is too small for a track day. It holds ~0.25-0.3 gal."
I track my car and have the Cooling Mist 1.5 gallon.
The sessions are 20 minutes and by my third one, I am almost out of water.
My injector is an M5, way smaller than yours.
So your small capacity tank won't last even a whole session with an M10 alone, never mind adding an M7.
Agree, you need something bigger.
Install looks super neat.
Post picture of the added/modified bigger tank later.

As far as response time to boost, I have tested this enough to know that it is absolutely accurate and instant. I am not sure why you are seeing a delay but you should not. I test the system every single day and I am certain there is no delay.
I use it as a boost gauge in my 135I and its accurate and fast.
If I can help you with anything let me know.
