Have you finished the install? As there isn't any room for an intercooler on mine, I will probably do
a kit like this. Where did you get it?
Anxious to see your results!

Installed a water/meth kit, lower egt's and a little more power!

The cool new gauge
Just have to weld up a mount for the tank.

I will get it all sorted out this weekend. I had to change out my radiator to be able to fit the intercooler I have. I used the radiator, intercooler and condenser from a FedEx truck. Fit perfectly with very little modifications, and cools much better than the stock setup.

When I first started driving the 4700 I found the engine to be incredibly sluggish. It turned out to be the terrible automatic transmission, the Allison AT500 does not have a lockout feature for the torque converter. After a little tranny swap (look back a few pages) to a Eaton manual the truck came to life. Then came a few adjustments, fuel rate, preboost, injector pump timing and installing a huge intercooler. Tipping the scales at close to 17K pounds it can happily tow my 6800 pound camper like it doesn't exist. I am really looking forward to towing with the water methanol kit. So far driving it with water/meth has been amazing!
My biggest bit of advice is to get the service manual, it show all the settings for manual vs automatic tranny injector pump settings (they are different). My truck was stock 12 degrees injector pump timing, where as manual tranny with an intercooler can be set 17 to 19 degrees. Mine is set to 17 and it woke the engine up, better fuel economy and much cooler egt's.
The DT360 can makes a ton of power, but I was shooting for the middle ground between reliability and performance.

I think we have a Voith transmission in ours; either way it has 3 gears and its awful going up hills and high climb switchbacks, which are our regular roads.
Years ago, one of the diesel techs I saw on a regular basis at my old job told me that we would be better of swapping in a DT466 into that beast than doing anything with the transmission; that didn't quite make sense, but I know he must be talking from Navistar's recommdantion. However I think it was last year, I ran into some backwoods diesel guys who told me "oh man, that motor has lots of bolt on upgrades that would help!" and mentioned something about taking the air pump from a Cummins 6.5 that I liked the idea, but didn't make sense. I think a transmission upgrade isn't out of the question; for us volunteers, we would probably go find a nice 4 speed Allison automatic.
