Traveller, with a daily street driven engine I am sure thats no problem, my engine 15 years ago would have cost close to $75k with the internals etc, and like a lot of FE owners who have gone with very expensive internals delivering over 500bhp to 700bhp with some big strokers it makes sense to get good
oil flow and filtering in order to compliment the rest of the engine.
Rick, I had a 1-1/2 HP6 adapter but went for the System 1 as it came with its 45 micron element, I phoned System1 and they said the 45 will take out the harmful particles. I agree any good race filter or good flowing filter will do, with filters people have as many differing ideas as with
oil products so its all good.
I looked at the Omni filter and they are no doubt a good product along with Wix, Fram etc and the full flowing Ford HP recommended filter, like Rosco and yourself use. Regarding Jet boats I guess they use the standard filter on the block, or a remote filter.
