Gary, I've been looking at oversized full flow filters and came across a lot of Fleetguard LF692 at $6.55 each.
Would they be good enough? The price is excellent and it seems to cross reference with the Wix 51794 which is about double the price.
It should work fine. ..and that is a good price. Fleetfilter's price is $7.60 ..and they're giving them away at that price.
Fleetguard are very good filters, are they not?
They're not in as widespread distribution as some brands, but they're considered a quality offering ..stratapore or not. Flow potential is not usually a problem to ponder. This is especially true with a filter that is about 150% of the surface area as the standard size.
I would think that most offerings from most filter man's would be comparable here (exception w/Fram probably). Donaldson does offer this big filter in the SYNTEQ (the shorter one they do).
Again, this should last a very long time from a loading standpoint.
Oh, the racing filter is not recommended for longer term street use. This is due to the course nature of the media. It's a rock catcher.
Chevy's, with their in block bypass valve make both a good safety and a minor liability. If the whole circuit is bypassed at something like 7-11 PSID, which on the surface is the same as most common oil filters, but the difference is that the oil in any other app just bypasses the media in the filter can, while in the chevy it bypasses the entire filter and, in your case, the sandwich/NTZ as well.
Now you can defeat this mechanism, and with the bigger filter I would have no worries about any issues of media collapse, but then you've got only the Permacool poppet relief for full flow operation. This is usually more than enough for most engines. Yes, as much as it looks unlikely, that little (it's bigger than you think if seen in 3 dimensions ) port handles the entire flow in most engines (also keep in mind that it's not like a pipe that chokes down for its entire length ). If, however, your oil pump is of higher volume, you may need to drill a VERY VERY VERY small hole in the Permacool sandwich. Repeat: A VERY VERY VERY VERY small hole if you see pressure affected by the setup IF the in block bypass is defeated.
Edit: Let me explain that a little more.
In the normal Permacool sandwich deal (when used as a feed for a bypass filter), the flow must pass through the Permacool relief valve and then goes to the filter where the filter's bypass valve works as intended. The poppet relief will attempt to manage 2PSID across the filter to the limits of it's capability ..which is usually ample.
In a Chevy (or other GM) the engine flow will see the entire ensemble as the filter.
Not too much of an issue of merit from a flow standpoint. It's only an issue of variable filtration when the in block bypass opens. Most of the time the whole setup will produce about 2.xxxxx PSID which is well within the in block bypass's range. Higher volume oil pumps could affect this, but not from a flow standpoint, just a filtration standpoint.
