Pressure is measured after the filter,not before. Think about it,if you have the exact same flow volumn but you have twice the filter area to force it through,you're going to have more oil flow through 2 filters then one. Oil pressure is resistent to oil flow through the bearings not the filters.With 2 filters you reduce the pressure drop across the filters then if you have a single filterUhh
2 filters REDUCE restriction eh??
Maybe im just a dumb michigan swamp rat but …
In the case of nothing changing but adding a second filter Oil pressure is resistant to flow ….literally. So if the only thing that changed is an added filter and you pressure went up , then flow went down.
I didn't see if the writer mention the plumbing config, filters in 'series' or 'parallel'. The latter is preferred after the first question I have w/filters.Gotcha
Well i guess it cant hurt to have 2 filters. Did it affect your oil pressure reading on the dash being there will be a little more resistance to flow?
I'm guessing you're referring to my set-up.Not my first kick at the can with dual filters,so they're mounted in parrellel,and sit well below the oil filter set-up on the 5.7's,so there's no drainback. I was running this same exact set-up way back in the early 80's on big block chebbies,that tells you how long Transdapt has been building their dual filter set-ups,lolI didn't see if the writer mention the plumbing config, filters in 'series' or 'parallel'. The latter is preferred after the first question I have w/filters.
Does the filter brand have negative back-flows? Yes, it will wick-down in time setting idle for some time, but make sure your filter will not allow a draw-back into the supply line when the pressure relaxes/cools on shut-down.
Series filter lines does not get what was intended. Filter #1 is building resistance due caught harden black carbon particles , then the oil pressure has to work thru the resistance of filter #2
What is the object for two filters? Go two years w/o filter chg?
Ask, what is it with all Magnum 4.7 eng lifters whining when oil pressures avalanches 15 points below average, don't muck w/the design ops pressure specs.
