Hi Fred,
Sounded like everyone really enjoyed themselves on "The Hill". We're already
planning for next year. We should even be bringing a 510. Yeah, I know.
Ya'll will all believe it when we show up towing it. ;>)
Anyway, the filters. I use old nylons all the time to make pop/blast
filters for microphones. The reason is that they don't pas blast of air
easily, but let sound pass freely. I would doubt they do a decent job of
passing air, at least at higher flow rates like you'd see in a carb.
As for the sock type filters I used them on the 42 DCOE we had on our
original 510 and while they worked okay, there was a wire frame (looked like
a large hair roller) that went inside the airhorn to prevent sucking the
sock into the carb. Now I can't help but feel that the wire frame disturbed
the airflow into the carb, particularly at higher RPM. Was is enough to make
a huge difference? Don't know without tests, but for the real world probably
not.
An alternative would be to get some K&Ns (or others), possibly from APT down
in Riverside. They have a wide variety of depths, diameters and offset base
plates (if needed) to fit pretty much any installation.
HTH, Ron
