High MPG work truck

I think the grill shutters will only have 2 settings, full open and all the way shut.
The half ton springs were so dead they were acting more like solid steel bars than springs. The 3/4 ton springs still have a lot of bounce to them..

I've enjoyed reading through your thread and kudo's on the many modifications. I can only add that you can gain significant gains with water depending on how it's introduced. The better the disassociation of the molecules the better. Also if you can do that you will see the larger benefits not to mention a very clean exhaust. I've done a bunch of research related and have it utilized in different system and device designs to some gasoline engine induction system changes I've made that you can read about here. It relates to increasing adiabatic efficiency along with of course volumetric that you already achieve with turbos. Keep up the good work and look forward to more or your accomplishments on your truck!

For the next round of water injection I am putting the injector on the cool side of the intercooler. That way there will be a good 4 feet of piping for the water to phase change from liquid to vapor.
I am only going to run about 1 gallon per hour of water for fuel economy boosting. If you want the cooling effects you run a lot more water.

I picked up a NIB Ford shutterstat off ebay (for use in operating the grill shutters).
Not sure what temperature it opens/closes but it was cheap, $26 shipped.
Which is pretty good considering I usually see them new for around $90, or used for $25 to $35.

I wasn't going to make the comment but it was on my mind. Water will re-condensate and only be absorbed by heat in the combustion process and through some latent heat absorption. Water will not vaporize under pressure and that airspeed. Other inhibitors include binding energy, the chemical properties/formula of air, monolayers and surface states, add to the difficulty for water molecules to separate in that type of environment. Adding cooler temperatures will again add to re-condensate. Not to be confused with pressure behind water exiting a small orifice into a lessor environmental pressure Here's a link for example and further definitions and somewhat relate as THIS can provide a lot more information to phase change of water in certain environments. Just wanted to point that out as some of the science isn't always intuitive and many variables add to the complexities of it's operational characteristics.
I look forward to some more posted pictures of the project btw.

I have already worked out that the water will not fully vaporize in that 4 feet of piping.
The air will be moving between 70 and 80 feet per second.
This will be hot dry newmexico air and will only be under 15 to 16 PSIA most of the time.
Hopefully it will vaporize and cool a lot better than when I had the misting nozzle on top of the intake plenum.

The best way to vaporize it would be to send it through a turbocharger compressor.
But then the water tends to condense in the intercooler.

With out other details, I would agree with you on both points. You are better off where you have the introduction now! Keep up the good work. I live in this hot stuff too although we finally had some relief of rain in the past few days.

Lost 10lb and found better cooling all in one box:

Yea, I like that. Read a bit of that thread too.

Latest thing is an "oil to air" engine oil cooler that shuts off oil cooler flow while the engine is warming up.
For version 1 I am just going to wire the oil solenoid into the "cold start circuit" which cuts off after the engine reaches 120'F. This is fine for summer use.
When winter rolls around I am just going to cut off the oil cooler all together with a manual valve, or at least shut off 80%-90% of the flow.
