Oil Filter study

[Bob In Ct]

I'm currently using a 27 micron Moroso racing filter (Mobil1 filter is about 9 microns). I figure the oil is far more apt to go through the filter than to bypass it, especially when it's cold. Since I started using it I've noticed a slight increase in pressure.

Hi Rick!

We ran a filter on our racing car, without bypass in filter nor in the adapter plate.
Not knowing the flow capacity of that setup we ran out of oil pressure.

One of the more experienced engineers confirmed that a: our setup is correct, b: the filter in question had not enough filtering area when new, let alone used. I think it was a MANN.

I cut it open and found debris in the "fold" of the paper. Of course. All oil was forced that way.

Now, which filter has enough capacity if you run all oil through it?
And what is the max pressure? When will it burst?
