Baseplate holes vs baseplate holes

[Ignatius]

I’m bumping this old thread for this:
A Fram XG9100 vs an AcDelco PF2232. Is there any reason to think that a Fram Ultra would be restrictive on my 2017 L5P Duramax? The PF2232 and XG9100 have the same number of baseplate holes but the Fram’s are noticeably smaller.

Why bump a nearly 3-year-old thread just to post some information from a known clickbait troll? Below is a link to the most recent thread he came into on BITOG to try to stir up again.

Fram Ultra or Hyundai OEM for 5K mile OCI ?

Fram is the only company I know of, who uses oil soluble glue on their filters.

I’m well aware of who he is.... that said, he does have a valid point about the base plate holes on this particular filter. I just installed an XG9100 on my Duramax. There is a bypass valve on the filter mount/cooler so there is no danger of starving my engine for oil. I just wanted to know if the base plate hole size matters?

As long as the baseplate holes have a larger area than the hole in the pipe it won't matter how big they are

Sure, but the total flow area of the base plate holes would have to be much less (like half or more) than the area of the filter mount inlet hole to the engine. The media typically contributes most to the delta-p across an oil filter.

Measure the ID of the oil filter mounting stud flow hole, and compare that area to the total base plate hole area. Also ... engines use a positive displacement oil pump, so even it Filter A has a bit less base plate flow area than Filter B, it's not going to cause much increase in PD pump output pressure to force the same volume of oil through it.

Go read this thread where @Ascent Filtration Testing does ISO testing on flow vs pressure drop across the whole oil filter, which takes into account base plate holes.

Would you all like to see ISO 4548-12 Oil Filter Lab Testing Comparison, Efficiency & Capacity, Pressure vs Flow, Bubble Point, and Burst?

You switched your temps here, but yes exactly. It's easier to heat a fluid up then to cool it down to reach a target viscosity. I also don't like to get fluids to hot. Around 40C is where I don't like to go beyond if I can help it. Nice graphs and homework on this equivalency!
