Filter Minders for Dummies

[davidbrady]

For completeness I called Racor Parker and spoke with them about the air filter used on my LXi. I'm running an ECO-SM 099842007. Racor gave me the following restriction specs for that filter. The DD S-60 has a full tilt flow rate of 1170 CFM:

4 in of H2O at 1120 CFM
6 in of H2O at 1400 CFM
8 in of H2O at 1630 CFM

So adding the filter into my previous calcs gives us an overall restriction that's probably half DD's clean air filter requirement of 12 inches of H2O. I think we're good.
