How far past max lift would you like to see it "flow well" .050?.0100? more? and by "flow well past" do you mean the CFM should still be increasing or just not backing up a lot? if it just holds the peak CFM from say .350-.500 at a fairly constant CFM but isn't gaining anything or dropping off at all is that okay?
Thanks

Brad,
It needs to be on the flow bench and the quietness is the sound of the air. Usually test 0.100" ~ 0.150" past your required maximum lift and don't worry about the behavior past that limit.
