Ive skimmed through this thread, wow alot of info. I voiced my opinions on everything stated.
To the original poster, the 6637 has showed MUCH better filtration than the stock airbox, and comparable filtration to the AIS. Mech's picture just shows it, sled pulling is harsh on a truck.
I do not belive in the TAG products, i belive the theory is perfect, but when transfered over doesnt make since. I got 165K on my truck, the turbo was replaced once due to....................DUSTED TURBO, lack of filtration. I checked my turbo a month ago, this turbo has over 220K on it since the motor it was pulled off of had that many. And it still does NOT have a play in the shafts. Im going to check again soon.
Im going to start a thread with a poll, turbo failures, and see what happens.
Well, the original ? was if the Kwik filter led to an early demise of the turbo. I am not sold on the theory that an open filter element leads to a vortex thus destroying the turbo and therefore am prepared to test this. Since I throw nothing away, my wife hates that, I can even test this with my stock filter. I just have to go to the shed and get it out. We may or may not know some results when I test this. That is why we test things.

This sounds like a good idea, but figure a way to get a breakdown of what % of the total miles were used for towing, running empty, etc.. I think the potential damage and accelerated wear only occurs at say 12 psi and higher boost, so getting people to estimate the total % of their miles at this boost level would get the best data.
I've been trying to go back using my wife's travel diary for the past 9 years an figure mine this way. For example, towing on the flat at 65 mph, with no head wind, I hit 8-12 psi boost, at 70 mph or with a little head wind or up a slight grade, and I'm up to 12-16 psi, and pulling a grade in 3rd, I'm doing 16-22 psi, and I'm therefore between 8-20 psi for 300 or more miles all day long when I tow. Driving around empty, I'm very easy on the truck, and never exceed 8- 10 psi, and then just briefly getting away from a stop.
Exactly what I believe as well. Very common occurrence, and that being the case, a question.
Why aren't jet engines built with a TAG like device to prevent it?
The air when it hits the fan is "straight" due to ram air effect. Most anything that is added to straighten airflow also increases drag when in turn uses more fuel. Not to mention the fact that if it breaks off and goes through the engine it can get rather expensive. Thus my reasoning of why I would NEVER put any kind of device in the intake of my turbo! Any effect it MAY have would be negligible at best and in my opinion, detrimental to engine performance.

In other words...
Snake oil
So what's the explanation for these improvements?

I know it's a Dodge, but the turbo principle should be the same.
I disagree, and I think that jtharvey got it right in the above quote from him.
In any case, Tenn is going to install an air flow gauge and do testing with his open element symmetrical filter, and I wouldn't be surprised if this doesn't eventually include testing with and without a TAG as well.
A quick drop here, where are you now Gene? Left Marquette yet?
We are now in Superior, WI, just across the bay from Duluth, MN. We plan on leaving here on Aug 7, and heading west on either US 2, or maybe cutting over to Fargo and picking up I-94.

I vote US 2 but you will have to go around Glacier National park. The road going through it is impassible for anything larger than a pickup truck. It's worth stopping there and driving the Going to the Sun Highway. Absolutely SPECTACULAR scenery and this time of year is the only time it is open, I believe.

I don't want to turn this into my travel thread, which I haven't gotten around to updating, but I will. We're considering I-94 & I-90 to Missoula, then north on 93 to Glacier for a few weeks, and then back tracking to Missoula to save the last of my brakes!
I'm getting concerned that all the stop and go on US 2 is wearing the last of my original brakes faster than I'd planned. I was down to about 5 mm all around when I left Hagerstown, MD, and originally was planning to stop at Rockin S Performance, Ft. Lupton, CO, which Guzzel recommended, to get a complete brake upgrade. Then came the Reno fire, the extra hot weather, and the unplanned detour north. I'm going to try and nurse the brakes until I get set up somewhere this winter near a good shop to upgrade them. I'll put out a request for recommendations when I figure out where that is likely to be.
It just occurred to me that since this thread is named after YOU, there should be no issues answering any of YOUR posts here!
