I'm thinking about getting into water injection to help clean up after my WMO and lower the EGTs.
Couple questions:
-What percent **** is in the -20° washer fluid?
-What is the average water consumption? How many miles can you get one one gal water?
I plan on finding some way so it only runs above 5 psi, although most of the time i need the extra cooling is when pulling hills in 4th, under 2k rpm (usually not much boost).

1. According to this link 35% (see very bottom of page for info) enginerunup.com
2. I have a single 375 ml per hour nozzle in mine, thats the smallest nozzle Snow happens to sell for their "universal Stage 1 diesel kit" Thats 375ml per hour assuming full flow, all the time. So IF I could get full flow all the time (my heads will blow off first or I'd be doing about 130mph) it would take roughly 10 hrs to drain a gallon. So in other wards, it lasts a VERY long time.
Boost controller: Call Snow Performance and see if they'll sell you their boost controller. Its' electronic, and you can set it for your start levels and max power levels. I.e. have it come alive at 5psi, and be at full power at 14psi, or whatever you want really. All you have to do is feed it a line w/ your manifold pressure and it does the rest.
You could go way to the cheap side and just use a Hobbs switch that actuates at 5psi. The early Snow performance kits worked this way, I had one. You basically use the Adjustments on the Hobbs to make the switch to power your high pressure pump for your water **** system. The downside to this spartan method is it's "full on" as soon as that switch hits. You may find "full on" @ 5 psi is not a good thing for your engine. On my Cummins when I first put it on, I had it set to kick in around 20psi IIRC, and you'd have thought that Cummins was gonna do a front flip right outta the engine compartment. It was a horrible feeling watching/feeling that happen. Point being, this stuff takes some fine tuning to work.
It's just my personal opinion, but water ****, as great as it can be is a little like walking around blindfolded in the garden of eden picking apples off trees and taking a bite. You just hope you don't take from the wrong tree. Too much liquid injected too soon is a hydrolock waiting to happen. Myself I'd just pay the few hundred and get a proven system (whether it be Snow's or someone else) and know that when you use it you've got the best odds of having success with it.
FWIW I have my Stage 1 kicking in @ 7psi and full on @ 18 psi (which I don't run up too, I'm just erring on the side of caution for now) Its too dang cold here to determine if these are the right settings for me in the end, but thats where I've started.
