There really is a science to the design of air filters. When you require the air to pass through a round slit, make a 180 degree turn, run through a few inches of mesh, make another 180 degree turn and then into the carb, how well is it really going to flow? If oil bath filters suit you, then use them. But they are not superior to modern filters.
And you have the aerodynamic analyses to back that up?
First, we were told that an oil bath filter was messy and inferior. Then we were informed that the large openings in the mesh was what the problem was. And now we're told (without evidence I might say
)that the air flow through an oil bath is more restrictive than through a paper filter. Hey, if you want to use a paper filter go for it. It ain't my truck so I really don't care. However, without data, we're all just voicing our opinions and I know mine is always better than someone elses :p
Oh, by the way Hot Rod Dad, this whole thread started with the idea of putting a paper filter
inside an oil bath filter. If you are correct in your air flow analysis, then we still have the air flow "problems" of the oil bath cleaner plus the additional restriction of the paper filter. Seems to me we now have the
worst of both systems.
