OK. I think I understand. What happened to the 13/64 holes you first mentioned?
Whats on the "bottom side" of the sandwich adapter? A regular full flow filter or a "block-off" plate.

Would they all flow the same?

I put them back where I pulled them out of
I'm glad you asked this. I was (obviously) confused about it ..so I went out to the garage and got out the drill index to see if my chemical-electolytic memory suspension was in some lame state.
I don't have either a 7/64 or 13/64 bits. A 15/64 will not fit and a 11/64 moves smoothly through the holes. My 3/16 bit is missing.
but for my lack of precision (and I do thank you for bringing this up
Great obfuscation. You're definitely upper level management material.quote:

but for my lack of precision (and I do thank you for bringing this up) ..we're still dealing with two relatively small holes supplying the engine. When you look at a standard Permacool with its single poppet relief valve ..this is adaquate "assurance" that you can basically dead head the outlet port and suffer no loss in volume capacity (some limited conditions and restrictions apply).
So were talking more like two 3/16" sized holes?

Yes, my self grooming is definitely geared to upward mobility. You would think that I came up with a few of Fords better ideas ..and they wisely promoted me for, 1. pulling off a lame design and getting it out the door before crashing - meeting sales demands ..and two ..to get me out of the drivers seat before I did any more damage.
Yes, it appears that these are approx 3/16 holes.
Perhaps a hair bigger then the 5 out of the 6 holes on my ST-16 sitting right next to me (Champ has one bigger hole that is used in process of manufacturing) ...or 1/3 this filters end plate flow capacity.
Keep in mind that this is the one that failed to provide any differential after warm up. It's not the one in use now which has no holes drilled in it.

OK then. Then the way I see it, you have a huge 1um filter that apparently doesn't significantly restrict oil flow when cold, however, with the bypass valve in the sandwich, we don't know for sure. And while your experiences here with the "holes/no-holes" sandwich adapter provide some insight, we still have some unknowns as far predicting how often and how much a typical "small" full-flow filter goes into bypass mode, especially as it accumulates miles. Further, even if it goes into bypass mode occasionally, we're not sure how significant it is to engine wear. Finally, data indicates that a 1um and smaller bypass filter used in conjunction with a typical full-flow filter will keep the oil cleaner and thus may reduce engine wear.
Even after all that, I'd still like to see a test with just a spin-on adapter and a single remote mount with a typical full flow filter, with gauges before and after the filter where all the oil is forced through the filter so that we could have some hard data on this subject.

For some other reference points, the ST-3950 I have has 5 holes of 1/4" diameter each and a sixth one that's even larger. The baseplate has a "Y" stamped into it.quote:

A ST-3600 I have has 7 holes of 7/32" and an eigth that's much larger than a 1/4". The baseplate has "AA" stamped into it.

All too true. I am basing my belief on data derived way out of the box and not on the principle subject that I'm applying the data to.
My list of experiments is getting backed up a bit. I feel satisfied with the functional performance of my mega filter ..and feel confident that it will serve my needs for longevity. It would be an impractical installation for most on this board.
So ..let's see if we can get to where "the rubber meets the road" on this typical everyday filter thing. It may take me a few weeks ..but I'll dismantle my monument to X-filtration (visions of Xtreme tv as I flip channels) and plumb my various part together to make a go at this bypass question. Luckily everything is nice and somewhat modular ..so it's just spinning a couple of nuts and one or two bolts.
I think that I can use my dual mounts for this REAL experiment. I'll just cut a thick enough gasket to cover one of the filters of choice's inlet holes. The dual mounts already have 1/2" ports at either end that I'll just bushing down to 1/8" on one end for the pressure senders. I can determine if only one filter is working by temperature.
For the sake of leaving no stone unturned here...I will probably do the first run with the smallest available filter. In the Ford/3/4-16 thread type ..I also have an available supply of used filters (currently in use). The whole fleet has the same thread/gasket size. Everything from my son's Cherokee and Neon ..to my wife and my jeep ..my Caravan and my daughter's Taurus. That should do it for the bypass valve testing. I also have a Chevy thread dual mount that I can also use in the same manner.
I went to my hot rod former racer wrench's shop to day. All the gear heads keep looking at my "Flux-capacitor" oil filter ...and just shake their heads. I keep trying to tell them to look at it not as a vehicle enhancement ..look at the vehicle as a test platform for the device. Nothing against my gear head pals ..but..they just don't understand
Do we need a new topic? "How I intend to end the bypass valve debate" and seek whatever will satisfy our various members for covering all the bases????
