Newb Oil Filter Question
Both were done with the 90. Even a short filter won't fit on one set of dyno headers I have out there. And I'm pretty sure I can't get a shorty on with my headers either, but I'm not 100% sure of that ATM.
When I put my clunker on the dyno I will check to see if I can fit a short filter with my headers.
Unless I'm missing something, I can't think of a way to check the pressure drop across the filter without using the adapter. There is a port on the adapter I can use that shows pressure off the pump. So between that port and the oil pressure gauge port we can see the pressure drop across the filter.
I know I checked this probably in 1984, but it was on the car and there was no way to data log it back then. Plus I have totally spaced off the results due to the passing of time. And some jerk *** stole that note book.
So you're comparing apples to oranges then, and working off of a 40 year old experiment. Got it. You said the 90° adaptor was less restrictive than a shorter filter, but you never tried it? All your data was with the 90° adaptor then? C'mon man.
The short filter is a far greater restriction than the right angle adapter.
Based on no data, because you didn't test it, as you said yourself.
Any good set of headers will require a right angle adapter.
I don't know what you're running, but both Doug's and TTI long tubes clear the shorter filter just fine
without the 90° adaptor, and they're pretty much the best you can buy off the shelf for an A-body. And the PS-2004 I run is shorter than what can be run too, because that Canton plate I run is thicker than the factory sandwich plate.
Chrysler knew the short filter was a bigger restriction. Keep it and use the longest filter you can fit. You engine will appreciate it.
Any maybe what Chrysler knew 50+ years ago isn't relevant anymore? Because just maybe filter technology has improved since then?
The Mopar filter I linked, which also fits the Doug's and TTI's without a 90° adaptor, is used on Mopar V10's (Vipers!!!), Gen III hemi's, and just everything with a magnum engine, etc. Just look at the application list. All of that stuff makes more power and lives longer than the LA's did from the factory.
