Sorry I have no new info.
I just wanted to say thanks to FordCummins and others who are refusing to let this die. When my contact at Donaldson told me the project was axed, I gave up.
I'm sorry I quit, as there may still be some good news to come out of this yet.
Let me share with you an anecdote about this Donaldson filter. About 8 weeks ago, I had to drive for an extended period on a VERY dusty road (Wyoming back road on an Army explosive test range). I drove about 20 miles in the dustiest, nastiest silt I've ever experienced (I've never been to Baja, which I hear is the worst).
After this drive, the entire underhood area was COVERED in dirt. It was so thick under there that you could NOT make out any of the lettering on the batteries, and you could barely even make out the raised lettering on the valve cover! I got home and used some compressed air to blow off most of the dust.
I decided to see how well the Donaldson filtered this mess. I removed the filter and inlet tube as an assembly (remember, I had the inlet taped inside the filter outlet) and checked the turbo. The turbo was clean.
I set the filter on the the ground on it's face, and inspected the inlet tube. SPOTLESS. Not even a residue! I could drag my fingers across the inside and they would come out clean. No finger tracks on the inside, either.
But the BIG surprise was when I went to reinstall the filter. While it was upside down, a lot of the dust that the filter had caught poured out of the filter on on to the ground. When I lifted the filter up, there was about two handfuls of dirt underneath it when the ground was previously clean! It was holding and trapping a LOT of dirt (for a filter). Probably enough to fill two, maybe three shot glasses or so.
The funny thing was that while all this dirt was in the filter, I noticed no change in performance or increase in EGT whatsoever! The filter apparently flowed as well as it did when clean and new!
This filter is probably "lifetime" for me. All you have to do is turn it upside down and a lot of the crap that it trapped will fall out. That's the easiest way to "clean" a filter that I've ever seen. Well, it won't clean it. The media is getting blacker as it gets more use. But it's holding up very well to severe dust, and temp extremes.
All the while, it's flowing like a champ.
