I wanted to get everyones opinion, as I am fairly uneducated when it comes to this matter. I have, as my alternate air source, ram air that is unfiltered in to my IO-390 with AFP fuel injection (very similar to Dan Checkoway's setup). I do get quite a boost, but I ave been afraid to use it at low altitudes out of fear of all the dirt and junk floating around (not to mention bugs). I have used it quite a few times up over 5k+ (4k+ agl) where I fealt comfortable that the bugs weren't as prevelant and there was probably less dust/dirt floating around compared to down low.
Some people have told me I am being paranoid, that aside from dust storms or other obvious dirty air situations I will be just fine at say 1k' agl. Others have told me that I am crazy to have unfiltered ram air at any altitude.
Does anyone have an opinion, or info that they can pass along in educating me about the use of my ram air at different altitudes. By the way, I am in MN, it is well below freezing 1/2 the year with NO bugs at all, plus with all the snow and such there is no dust blowing around like other places in the US.
