A few weeks ago I bought (but haven't yet installed) RJC's Biggie Filter Adapter.
For those not familiar, this clever, simple little part allows replacement of the stock PF47/PF52 oil filter with a larger PF24 filter. I've since been wondering how to use an even large filter, without the expense or complexity of a remote oil filter (eg PTE's TurboSaver).
In Baldwin Filter's catalog, the direct cross from the Delco PF24 is the Baldwin B39. The B39 has a BIGGER brother, the B9, which is 22% longer shell and otherwise identical.
Earlier today I bought a few B9's (a little under $5 each), intending to use them with my RJC Biggie to achieve my goal of a "Bigger Biggie". My purpose is to run a simple filter arrangement, with a lower differential pressure drop, which will lessen the risk of the Bypass opening and allowing crud/shrapnel to get back into the engine. While I don't have actual "Pressure Drop vs Flow" data, all else being equal, the bigger filter should be lower press drop across its filter media.
here's a link to some photos I took comparing the Delco & Baldwin
Photo 1 shows the 22% longer "Big Red" Baldwin.
Photo 2 is end view of the threads.
Photo 3 is a closeup of the gaskets, showing the height they protrude above the metal groove.
The Baldwin's gasket is better "captured" than the Delco, so the Baldwin should resist higher pressures without "gasket blowout".
The Baldwin had a very good anti-drainback valve, all 4 filters had negligible leakage when I blow thru the center hole. My single PF24 sample had a LOT of air leakage.
Both Baldwin & Delco had metal shells that seemed of comparable strength-- negligible deflection when squeezed (Purolator PureOnes seem disconcertingly flimsy).
Baldwin wrote me that the B9 is rated at 100 psi continuous operating, 200 psi burst, and 250ºF continuous operating temperature.
Later on I will cut the filters open and compare construction and filter media.
Overall, looks good so far.
What do you guys think of the risks of running this bigger Baldwin filter with the stock Bypass in the engine adapter, PLUGGED?
I've read some of the problems people have had.
I would be running the Kenne_Bell pressure booster plate (but no high volume stuff), using 5W30 or 10W30 oil, local temps never drop below 40-45F, and I am probably disciplined enough to not "race" the engine above 3000 rpm until it's warmed up.
