So now I am going to use the Gene sponsored gauge. Just got it in there today. Then spent a little family time. 104* out there today. Am I in Arizona now? Anyway, for those who don't know, I will be taking measurements so Gene can calculate flow in the later 7.3, and any possible restriction in the 6637. I will also be looking for signs of turbulence. I may be testing the stocker depending on what I see.
Here is the temp gauge install. Man that thing is ummmm, ugly, but I want it there to get a reading at a glance. It is a high quality unit though.

I will be trying to record boost, RPM, and restriction readings all at once. Maybe even MPH but really just for giggles because it's not needed for flow. I am going to need an assistant. I wish I had a video camera.
I cannot speak for what Gene will do.

Any way to figure out what kinda air volume (cfm) has to move through one of these 6637 filters before it collapses? If you'll remember, I sucked one of these through my turbo before, luckily only stopping up the CAC... mighta been a junk filter from the get-go. But my curiosity has the better of me.

I'd still like to know how that gauge will tell you if there's "turbulence" or a "vortex" in the intake. Especially since it's hooked up to the end of the filter. It's just a pressure/vacuum gauge. We used to have the same gauges in our tactical communication equipment shelters.

Looks good to me. I would thing the mag will bounce if it gets to a turbulence.
I was on a team at NASA that was monitoring the characteristics of the exhaust of a small rocket engine (end goal was to understand the patterns to be more efficient at burning the unburnt fuel...). We simulated it with a HUGE tank of compressed air, through a rocket nozzle, mixed with a vapor of some kind that showed up a YAG camera. We took pictures of the pattern coming out of the nozzle. Was pretty cool.
For now, the mag method looks just fine though!

From there, I may tap into the intake closer to the turbo for comparison sake. I am not sure it will tell me if turbulence or a vortex is present, or even what the gauge would show but I will be looking.
The primary purpose of this testing is to determine the flow of the 99.5 and up truck design across various bost levels IOT determine MAF and thus be able to predict HP potential with the 6637 and stock intake tube and stock turbo. At least that is what I thought I was doing. Any other results are simply gravy.
Ya gotta admit, at a minimum, that is one awesome filterminder.

The only question I have is whether or not the level of vacuum measured at the end of the filter housing is the best place to do so. Might be a truer measurement if you attach a piece of tubing that goes inside the filter and extends to the filter throat at the entrance to the intake tube.
The only reason I mention it is because you have a different quantity of air flow at the gauge end of the filter as oposed to where the air is leaving the filter and entering the intake tube, which will probably create different levels of vacuum from one end of the filter to the other.

I hear you Pete, I just don't know if there would be a difference.
Quote from my gauge sponsor/Gene:
So that is where I will start because that is the data he is looking for. I will likely move it after getting initial #s. Most likely to the green tube fitting in the intake hose to see what if any difference exists.
Quote from my gauge sponsor/Gene:
I'm primarily interested in getting CFM data on a 99.5 as a function of RPM & boost, but since we're also trying to see if there's some kind of turbulence or vortex effect due to the 6637 installation which typically uses a smooth piece of pipe instead of the OEM CCV coupler, it would be best to make the measurements on a standard 6637 set up with a test fitting in the end of the filter where many people install their restriction indicator.
