Subject: Re: Air filters X-Original-Date: Tue, 13 Dec 2005 15:47:54 -0500 X-Original-To: Lancair Mailing List X-Mailer: Apple Mail (2.746.2) According to Lycoming, my IO360B1F will gulp 1,150 lbs/hr of air. The K&N filter people say their filter material is designed to pass air at the rate of 6cf/min so it's relatively easy to calculate the filter area and end up with a cfm rating for the filter. Now, the question is... how does one equate lbs/hr to cfm in order to come up with the right size filter? Angier Ames N4ZQ N3ZQ
