Today I saw a dual remote on a pickup truck. The owner said that the bypass part takes a long time to warm up each day, until he gets two or three thousand miles on a dual filter change. After that the bypass warms up much quicker. Is this because it depends on the full flow filter build ing up some resistance so the bypass can see a bigger delta and flow more oil, and get it going a little sooner?
 
Yes, that's pretty much how it works. But the bypass element will always take a fair amount of driving to start flowing at full capacity. That's why they don't do much good on engines that do lots of short trips.
 
Yep. That's how my adapted Permacool reacted. Very localized heating of the BE-110 initially. Later in the OCI (12.5k total) the thing got fully enveloped thermally as the oil temp came up. I imagine that it would have been sooner if I had used a true Amsoil dual mount with the biasing valve. Instead I just swapped the inserts to fit the filters on my already plumbed dual Permacool.
 
My BMK-13 Dual Remote didn't take any time to get warm. But I have the biasing valve in place, which gives the bypass filter the extra pressure.
 
Gary;

Are you saying that your Amsoil bypass filter is run in parallel with the full flow filter from the pressure drop across the the Permacool?
 
I ran the BE110 in parallel to the SDF15 (I think). The only thing that induced flow across the BE110 is the differential across the SDF filter (actually the composite of both). Hence my flow through the bypass was less in the beginning of the OCI ..and more as the SDF ff got more accumulation on it.

This was because I had no biasing valve that is included in the dual Amsoil setup. That reactive valve will assure that there is a minimum static PSID across the ff filter. I had no way to manipulate that, except to perhaps put a gasket or something to cover some of the holes in the SDF (which I didn't want to explore).

I had to accept less efficiency at the onset of the OCI

Is this Amsoil setup that way to avoid having an extra line that would have to go somewhere like the oil pan? If you did have the extra line would the bypass filter work better?
 
Louie. Yes and no. It makes it so you can have both in one installation.

If you have a stand alone bypass ..there's no need for a remote mount for the full flow ..unless you don't like where the normal location is. If you're going to remote mount your full flow ..you might as well get a dual setup and get the bypass at the conventience of not having to route more hoses.

The biasing valve works just fine ..and does just that. It will always simulate a more loaded full flow filter so that the bypass filter will get a higher proportion of oil than it normally would.
