Re: cold air intake stats
here is some more info
Since I installed my 38R, my filter minder trips when I get on it. There are two possibilities:
I still have the "weaker" filter minder that I've heard about.
My modified Motorcraft AIS (Donaldson) isn't up to the task.
While scouring the net for CFM data on touted filter systems, this is what I've found so far (if it is all to be believed):
Stock CFM = 277
Napa 6637 CFM = 425
AFE Stage 2 CFM = 582
Motorcraft AIS CFM = 775
AirAid Stage 2 CFM (oiled) = 820
7.3L theoretical MAX CFM = 850 CFM
I'm looking for:
Something that doesn't trip the Filter Minder.
As quiet as I can get, understanding it doesn't get as good as the AIS.
The 6637 is out of the question because it fails at everything on the list... compared to what I'm used to. I've heard them.
Please feel free to poke holes at the numbers I acquired if you know better. If you're beast is using the Filter Minder (whine-free) and and more ponies than I am, what are you using? If you think my Filter Minder is failing miserably, chime in.
