2 port sandwich adapter pressure test

[jimmyjamesndt]

Another pressure gauge experiment, this time on an engine, 2.3 Duratec Ford Ranger, Motor Guard M-100, Derale 2 port sandwich adapter. One guage at the inlet of the Motorguard and one gauge at the return port at the sandwich adapter mounted in the cab, first pic is at hot idle, second pics is hot at 2250 rpm, that +10 psi must push a bit of oil through.

that +10 psi must push a bit of oil through.

Or the gauge's error is logarithmic.

Or the gauge's error is logarithmic.

They a mechanical gauges.

I took the lines off the Motor Guard and hooked up two matching gauges, jury rigged them with 200 mph tape, I see 3 psi differential at idle and a 13 psi differential at 2250 rpm. Not sure if this is excessive or not? Someone claimed anything over 2 psi is a loss in flow?

I looked through the numbers I wrote down, the in and out seems to carry the 3 psi through out the test range rpm's 2000-2800, when the Motor Guard is hooked up it's 2 psi. There may be a loss in flow at 3 psi when the sandwich is not hooked up to the bypass filter, 2 psi with the filter hooked looks about right.
Ralph would say if the pressure comes up and your oil pressure at the sender is good, the bypass heats up, you are all good.

New sandwic adapter installed, new adapter psi numbers.
Hot idle, 24 psi In, 18 psi Out.
Hot 2250 rpm, 56 psi In, 46 psi Out.

Hot idle, 24 psi In, 18 psi Out.
Hot 2250 rpm, 56 psi In, 46 psi Out.

These pressure numbers are with the Motor Guard hooked up.

I came across a post on a 911 forum on 2 port sandwich adapters, the ball/spring relief was set at between 7~10 psi for all models that Hayden manufactured at the time, this fellow worked at Hayden years ago. I think the Derale that I was using and the new Perma-Cool (looks like an exact copy) relief is set this way, posts on the old style Perma-Cool said it was 2 psi, this was from the Perm-Cool technical department, I can confirm that the relief is set for at least 6 psi for the Derale adapter.

Derale tech dept says the relief is set for 8 psi.
