So I had been wanting a water/Meth system for a while, Snow IMO wants to much $, I called Labonte 5 times with no answer, while that may be ok for some, this W/M is new to me and if I need to talk to some body for tech support, than I need to talk. D.O. did not appeal to me.
So I called CoolingMist, I spoke with the owner for 30 min. He answered all my questions and took the time to talk with me. On 12/15 I Ordered the diesel build a kit with the EGT option and no tank, I already built a 9 gallon tank. Recived it a few days later, Put it under the tree. Opened it X-mas day, planing on installing it Thur 12/30. 1 part was missing, so I sent Coolingmist a E-Mail at 9 am on X-Mas day, David (the owner) responded within a hour apologizing and sent the part out on Mon. Had it at my House Wed.
Mounted my 9 gal. tank in the tool box along with the pump(pic). Installed the 12.8 GPH injector in the intake right before the boost sensor(pic). I put the controler under the cup holder(pic). So I can adjust it easy but can keep it out of site as well.
Running 75% water 25% Meth. I have it set to come on at 7 psi and 750* EGT, at 25% pump output. Then up to 100% pump out put at 25psi and 1300* EGT.
I have called 2 more times with tech questions and David answered and was great.
On New Years day I orderd a few more things and He responded the same day.
With my 540 whp tune the EGT's would get to 1500*~1600*(by the end of a dyno pull) pretty quick, now the highest I see is 1350*
I will say I am very happy with the system and with CoolingMist.

That's a nice drop in egt.

I went with DO myself.

Still waiting for it to show up.

You're right about snows, too expensive for my wallet.

can you set it to come on at a boost AND egt point, or is it one or the other?

how does it get its readings?


You'll like the meth for sure!

can you set it to come on at a boost AND egt point, or is it one or the other? It's both. Both minimums need to be met, For me it's 7 psi and 750* EGT's, then it's a 2D map in the controller up to the maximum programed in the controller. Then you can assign a % to give EGT or boost more or less imput, 50% is equal.

how does it get its readings? The EGT option includes a EGT signal amplifier, that ties into your EGT probe wires.

You'll like the meth for sure!

I only wish I got it sooner. :D

Just interested why the DO didn't appeal to you

The DO controller did not appeal to me. I like a digital read out on the controller. I want to have the ability to inject based on boost and EGT at the same time.

Whats DO?

Devil's Own

So I replaced the 12.8 gph injector with a 10 gph and set the controller the come on a little sooner at 5 psi and 700* egt.
Works great for street, but I will put the 12.8 gph back in when towing or dyno-ing. I also installed a 90*elbow going into the intake for a cleaner look (pic). The kit comes with a 40 micron fiter and check-valve to install close to the injector but I wanted one for before the pump. So I installed a 40 micron filter coming out of the tank (pic).

Sure would like to see more pics of W/M systems, injector placement, tanks, controllers, solenoids ect.

your set up looks nice! Looking to do something similar. Did you see a very noticeable increase in power?

your set up looks nice! ~Thanks~ Looking to do something similar. Did you see a very noticeable increase in power?

I only run a 25% meth 75% water mix so the power increace is there but small.
I got mine for EGT temps, works great for that.

lots of miles, what filter is that?

Just a stainless screen type filter. I forget, 80 or 100 mesh

Its the black thing in the middle of the last pic right? How much was it? I bought an AEM filter that looks like an industrial filter

Yes, that's it. About $15 then add what fitting you need on it.

where'd you get it?

Tractor Supply.

I haven't check yet, but I've ordered stuff from Dultmeier (spelling). They might be a good source too

How tall is it? I feel like I lost $10, thanks lotsofmiles :( I guess I should take some solace in mine being 40 micron and 150 psi rated.
