Water Methanol Injection
Just finished installing my Cooling Mist water/meth injection system yesterday, so it still needs some tuning but that's basically it.
Heres where i decided to install the controller. Its visible, but doesn't blind me at night (it is pretty bright)
Had to build a fairly extensive wiring harness to hook it all up
The kit comes with a 1 gallon tank, but IMO that's pretty small for a diesel so I bought a 12 gallon tank from the tank depot, and installed it in the toolbox here. While the tank is awesome, I didn't expect the 6-8 week lead time to get it!
Divider to keep stuff away from it
Heres the tank:
Complete with a vented cap
sump, with 3/4" fitting
...and here's the basic idea
So I had to build a carriage to hold the tank securely, and get the sump high enough that the tank can gravity-feed the pump that will be installed next to it
Mock-up, with pump sitting there
Had to put a notch in the toolbox lid to clear tank
Carriage complete, with tabs for other parts of the system
Finished and painted
Note the foam padding on the straps, to keep them from rubbing on the tank
Had to install a float in the tank. When empty, it will throw an error code, and shut the system down so the pump doesn't run dry
Here is the general idea before the final install in the truck
On the side of the frame is a solenoid that the controller turns on when injecting. This defaults closed, so if anything goes wrong with the system the ground drops out and it closes, preventing the system from over injecting. Also closed when the key is off, so it is impossible for the tank/pump to siphon and fill intake with water.
In front, next to the pump, is the Failsafe Control Box, which is basically the brain of the system. It learns your system, and if it senses anything is awry, it alerts the controller in the dash, which is when the system will shut down and display an error code. It has lots of conditions for keeping the system in-line, and is tunable through the dash controller.
I opted to install these items here, in an effort to keep the system contained to the toolbox. The FCB could go anywhere, but I didn't want to clutter up space under the hood or dash, and it seemed logical to keep the solenoid close to the pump.
Ok, divider installed:
Wiring in progress. I like weatherpacks. Used em for years with zero problems, and they make the system easy to disassemble.
The supply tube is nylon tubing. I have it wrapped in split loom for extra protection
...and this is where the injector goes (pipe plug in intake). Moved injector post-turbo at recommendation of people on PSN
So that's basically it. I drove it to work for the first time last night, and it definitely does the job well! I have Baby Swamps (injectors) with an E4OD, 4.10s & 37s so EGTs are always a concern for me, but I was flying (needle pegged) and couldn't get it to 1200º no matter how hard I tried. Im gonna have to hitch up the trailer to get a heavier load on the truck, in order to tune it better. So yeah, its awesome.
