It's the new year, so let's get 'er done...
Subject is oil filter testing.
Specifically, we're hiring a respected test lab to run ISO 4548-12 filter tests on a Champion 48108, a comparable Tempest 48108, a Wix 51515 (aka NAPA 1515), and a K&P S-15.
Previous discussion here: https://www.vansairforce.net/threads/reusable-oil-filter.207816/
I've obtained multiple quotes, and settled on a highly respected lab familiar to many engineers here on VAF.
ISO 4548 is an international standard. The test procedure determines the contaminant capacity of a filter, its particulate removal characteristics and differential pressure. The above filters all have a built-in bypass valve, so the tests run until the bypass opens, or until element collapse. When done, we'll know a lot about our filter choices.
This is a cooperative effort with multiple contributions. Total cost is $5285, plus the cost of the filters themselves. Barrett Precision Engines ( https://www.bpaengines.com/) and Aircraft Specialties Services (as CamGuard, https://aslcamguard.com/aviation/) have generously agreed to pick up more than half the tab. Both are very interested in oil filtration; Barrett engines have a reputation for longevity, and Aircraft Specialty Services manufactures and/or markets a wide line of quality aircraft engine parts. Our own Doug is in; although Barrett is an advertiser, currently CamGuard is not. However, given the generous support, their appearance here is welcomed, plus a crowd funding effort (more in a moment) is approved. Kitplanes magazine is also in, and will publish an article in due course. Marc understands the magazine won't have an exclusive, but none the less has offered author compensation sufficient to cover incidentals.
Which brings us back to VAF. Full results will be published here first, but to make it work, we need that crowd funding. Specifically, we need to raise $2285 in cash, minimum. Contribute as you please (and every nickel is welcome), but it would be relatively painless if we had 23 contributors at $100 each. I'll collect, and be responsible for paying SwRI. I assume you folks trust me. It's about the same as the beer fund for the Vans Social, where I've been the bag man for more than a decade.
Do not send money yet. For now, pledge your contribution via the "Conversations" feature. For those not yet familiar, just click the silvery prop spinner on the left (or my name), then click "Conversations" to send a note. When we hit $2300, I'll be back here to say stop, and (unless you wish to be anonymous), I'll publish a contributors list.
EDIT, 1/17/24: STOP. We're now fully subscribed. Well done gentlemen.
I've already ordered the Champion and Tempest filters from Aircraft Spruce, on the grounds that we'll be testing representatives from the open market. I'll buy a NAPA 1515 at the local store, same deal. We need a few extra dollars for a K&P S-15, or a generous contribution if someone has one they will not be using.
That's all for now.
