Oil Filter Relocation for convenience and performance

Back to remote filtration....

I'm thinking that the only way to do more filtration capacity and still have acceptable oil pressure delay would be electric prelube.

This would turn the ports-in-series function of the sandwich adapter into a net positive. Put a check valve on the inlet of the sandwich adapter and push oil through it with an electric oil circulation pump.

Earlier I proposed using a sandwich adapter (for an oil cooler feed) to send oil to a remote head and keep the stock spin-on. I also proposed a "bypass" that would attempt to prevent oil pressure delay by cutting out the remote filter head under some conditions.

What I realize now is that it's not a bypass that's need, it's prelube with an electric pump. Here's what that plumbing would look like.

Sandwich adapter outlet--> check valve (low cracking pressure~2psi)--> run tee--> remote filter head---> Sandwich adapter inlet.

The electric pump circuit would look like:
oil pan drain plug tee-->electric oil circulation pump--> check valve--> enter remote filter loop at run tee
A schematic of this system might help understand the flow circuits better. If I understand this setup, you'd be pumping oil out of the sump with the pre-lube pump and sending it to the remote filter, and that oil would dump back to the oiling system after the normal spin-on mounted on the engine? Would the pre-lube pump be able to over come the necessary pressure needed to give adequate flow through the remote filter? If there is back pressure on the check valve from the engine oil pump, then the pre-lube pump would need to over come that and the flow resistance of remote circuit.

Interesting ~ I've Run a few Remote Oil Filter - Re-locators , always seems to much easier to do Oil Change
Being even Out side Engine Bay & in Wheel well did Run Cooler to Point I had an Insulation Sleeve for Filter in Winter
As Thermal Block to Wind Chill Factors . .
 
Forget about a remote oil filter as it's more hoses and connections to leak or fail.
Another thing to be careful about with a remove filter setup is the added dP of the remote circuit, especially with cold oil in very cold climates. If the remote hose length is too long and/or too small of hose ID is used, the added dP can put the oil pump into relief much sooner and that can cut back the oil flow to the engine significantly.
