Interesting. Now I wonder what the numbers would be if you systematically changed out intake parts individually from stock so you could see what the actual limiting factors are with the stock intake setup?

Air takes the path of least residence, so any little molded ridge or jagged edge will create the slightest bit of hinderance in flow. The stock airtube has that flex piece so that is a start (all of the jagged edges), I'm not quite sure where or what else in the tube or Airbox hinders flow but I'm sure there are quite a bit of things due to the need to be able to mass produce these things fast on fords part. The PMAS reps would be able to answer this question more accurately than myselfInteresting.

Oh trust me there is LOTS in the upper and lower parts of the airbox to hinder the air flow.. I had to cut it all out! lolAir takes the path of least residence, so any little molded ridge or jagged edge will create the slightest bit of hinderance in flow.

Hood up but air temps were higher with pulls on our kit as the room was hotter by 10 degrees and the car wasn't moving for any of the tests. If anything temps into our filter would be higher because more air is being drawn from the engine compartment that way and not as much from the grill opening.Thought I'd jump over to this thread.
2 questions for PMAS…
1. Were your dyno tests run with hood open or hood shut? Sorry I have to bring this up but with your design wanting to seal to the hood I need to compare apples to apples and I don't drive with the hood up.
2. Do you think it would be a good idea to open up the honeycombs in the grille in front of your intake to flow more air? In other words are those 4 holes in the grille a restriction or not? Would more holes be better for your setup?
Thanks you have been great with your communication on the site here.
Ya I would be interested in seeing those too.PMAS do we have any final install pics of it with the heat shield and blue filter ;-p
Also a picture from a better angle like top down.
this!.. I have been thinking about opening that inlet up as well. I cant see it hurting anything but if there is no intake box would there really be a purpose since that incoming air wouldn't really make it to the filter? I guess some "cooler" air would be better than none at all. I think that is the ONLY thing I don't like about this intake... lack of actual incoming cool air from outside the hot motor bay. Maybe it does use that air somehow and I just don't know it ??Thought I'd jump over to this thread.
