Baxter Performance oil filter adapter

I understand what you are saying. Put the media can not pass that much oil at 70psi so the bypass will open.

It's not the pressure, it's the volume. Won't matter what the pressure is if the filter media can pass the volume. It could be 100 psi and it not open IF the filter media doesn't cause a pressure differential greater than the bypass valve is set for.
Pressure doesn't matter - volume does.
If that filter is dirty or the oil thick, the bypass could open with the pump only pushing enough volume to build up 30 psi.
Pumps deliver volume, not pressure.

the higher the pressure the higher the volume

Pentastar don’t have problems associated with lack of oil pressure/flow/lubrication at start-up.

Pressure is resistance to flow. High flow can exist with low pressure and high pressure can exist with low flow, all depends on the restriction.
What I am curious is how have you determined a “by-pass” is opening specifically at 70?

Guys, 99% of readers don’t understand the fundamentals of DP, CV’s, or how full flow oiling systems work —and that 100% okay in this case, because:

Pentastar don’t have problems associated with lack of oil pressure/flow/lubrication at start-up.

These Baxter devices are discretionary toys. That’s the critical take-away we have an obligation to convey.

It had better not........ not unless cold or the filter is dirty etc..
It shouldn't open under normal circumstances.

My 73 runs 3200 RPM at 65 mph..........and yes, pressures running 60-70 psi.

Note the top sentence here from a filter manufacturer -

And from another - "when the filter gets clogged". Not when there's high PSI.

Anyone know why they changed the recommend Wix filter from a 57045 when the kit first came out to now listing a 57502?

I literally shit canned mine..........leaked no matter what I did. And I have spent more time wrenching that most have on trails or off roading. It was a POS.

Well, there is only two differences, the 57045 is almost 1" taller but the 57502 has a 22 PSI bypass valve rating vs. the 57045 having 12-15 PSI rating.

If I was take a stabbing better guess of the two, they went with the 57502 for the higher bypass valve rating. The bypass valve for the OEM cartridge filter setup is in the filter cap. Finding exact published ratings on that is somewhat difficult.

I actually reached out to the owner of the company through their support page, I got a reply back from them stating they changed to the 57502 due to its shorter height, He said due to variations in the engine covers some were having clearance issues with the taller 57045 filter so they changed to the 57502 which is an direct cross reference for the mobil1 filter that is recommended. The mobil1 number is the same as it has always been.

I was using the 57045xp since this product came out without issue and never had any clearance issues but recently ran out of them which is how I stumbled on the part number change. The 57502 also cross references to a lot more filters so theres that as well. Hope this helps some people out.

Figures, I always lose in a coin flip.

You and Mike Wolfe. So he'd let Frank do the coin flip - Frank usually won.

Can you cite your source for that statement.

It seems to me that all engines have "problems" with lack of oil pressure at start-up unless they have a pump that pre-pressurizes the lubrication system before starting the engine. No oil pressure = wear. The question is how much of a problem is it and how much will be gained by building oil pressure more quickly at start-up.

Yeah.
Me.

Sorry, not correct. If this was the case, then there'd be failures of all sorts of equipment, including those engines with only splash oil systems, and other machines using drip oilers and so on.

Oil "pressure" is NOT what protects and lubes. Pressure is a side effect of the volume a pump puts out against a resistance to flow. Pumps put out volume, not pressure.
The oil film protects the parts, not pressure.
No oil pressure != wear, no oil pressure only means no flow, no refreshing the oil film and leaving film there.
Automotive and farm equipment engines didn't have oil pumps for decades - that's a modern bit, and yet - there are engines in cars and tractors that to this day don't have appreciable wear because of the fact there was a constant oil film.
There's no oil pressure between lifters and cam lobes on a legacy V8, so in your theory, they'd self-destruct in hours or less.
Think of the incredible pressure between a Chevy or Ford or AMC rocker arm and fulcrum when the valve is quickly pushed open by the rising lifter and push rod.

These also build pressure, (from a fast building FLOW or volume or oil) refreshing that oil film between parts like rod bearings and journals, cam bearings and journals, followers and cams, and other moving parts as quickly as they start. The pump starts off in high volume mode, then drops back to low volume mode and about 30 PSI as quickly as they start.

A 1936 F20 tractor I had, had obviously been used in the field for years - a lot of hours on it based on the wear on external moving parts, parts not frequently lubricated, and yet internally, in the engine, there wasn't all that much wear. The valve train was lubricated by two trays just under the valve cover. Each tray had a sort of felt. You opened caps on oilers in the valve cover and squirted oil into the trays. During use, the oil dripped down onto the valves and rocker arms up top. No pressure.
Other internal parts on such engines of that era were typically splash lubricated like almost all lawn mower engines up until recent years when RPMs were slashed per government regs and so on.

Oil pressure doesn't protect the parts - you'll find that out there in some posts by engineers. Oil film protects parts. As long as a film exists, the parts don't touch each other.
Oil cannot be compressed........
