I didn't read the thread. But I'll offer this info ...
If its the low pressure drop you are concerned about, the filter elements inside racing oil filters usually have more pleats per inch, and therefore they have a much greater surface area of filter media, this results in a lower pressure drop.
Don't be confused, if you spend the extra bucks for a racing oil filter ... you're buying a much better filter. Otherwise the racing teams wouldn't use them on their very expensive racing motors.

The main difference between the FL1A and the FL1HP is the bypass relief valve opening pressure: 11-14 psi vs. 22 psi.
The FL1HP will pass more oil through the filter for a given period of time than the FL1A given all else being equal. A good thing. Is it necessary for a show car driven to cars and coffee once a month? Probably not, but what the heck.

Yeah, you got that, tomorrow AM Cars & Coffee! You be there for the caffeine? Those dudes on the cobra website were talking about micron rating as well, like the FL1PH was pretty high but the FL1A was much lower. What the hey is that?

Didn't make C&C today. Maybe next week.
Simply put, the micron rating is the largest size of particle that will be passed through the media. Particles larger will be blocked, so the smaller the number, the cleaner the oil. The debate would be that is it really necessary to filter down to X microns for a given application.
If you had a high pressure aircraft hydraulic system with extremely close machining tolerances, and consequences of failure are grave, you want extremely fine filtration. These systems are complex and expensive.
An automobile engine lubrication system can tolerate larger particle contamination. What that limit is the debate. I don't know.![]()
