4m40 oil pressure?
Posted: Wed Nov 25, 2015 7:39 pm
What is the oil pressure range on the 4m40? I have googled and seen various answers. Everything from 50 psi at start to 30 psi warm and running vs. 4 psi at idle and 80 psi at 3500 rpm!!!
The reason I ask is I am looking to install my jackmaster sandwitch adapter with an oil bypass. This would come right off the oil filter area. I want to then pass a small segment of this flow into my frantz filter, and then into a 55 gph wvo style centrifuge for a final pass before returning to the engine.
The centrifuge won't engage unless there is 25 psi or more available, which is good as it does not use extra pressure at idle.
Will I be able to get 40-80+ psi for a sustained period or not? Will this idea actually work on my engine?
