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 myself

This, particularly the bold.

Years ago in college I did some flowbench testing of various intake tubes and air cleaners, and the 'accordion'/flex portion of an intake tract was always a culprit when it came to restriction. My guess is that the raised portions internally set up a boundary layer of airflow along the section of flexible tube, effectively restricting flow to a degree.

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! lol

Hi everyone. My car was used to develop this kit. First let me say I see no reason what so ever that other cars will see the same results. Car is stock other than ford resonator delete that I dont care for, to raspy. I am not a dyno operator or super tech but did spend 24 years as a tool maker so I do have some wrenching skill. Dyno pulls were performed by a very skilled and respected dyno shop. First off impressions is that it is very large and looks very good and in your face in person. It is a tight fit at elbow but when adjusted fits and clears hood. Mass air meter is a work of art and allows lots of room to grow. Driving impressions. I believe throttle response improved, Can hear the motor more, I have removed sound tube. Real seat of the pants improvement from 4000 rpm and above. Car idles and drives perfect. In my opinion this kit is for the real car guy that values real performance. 100% confident this will perform as stated. Did I say it is big. Now that I have said all this I do have to say that it is coming off as I have had a stage 2 procharger sitting in the garage for a month waiting to go on and can not wait any longer. Special thanks to Nick at P MAS. Everything turned out great.

Sorry, for some reason I want to keep the first Kit. Just thought it was kinda cool to have my car used to develop something for the mustang.

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.

Thought I'd jump over to this thread.

3 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?

3. Will you offer a warranty/limited warranty on the included MAF sensor included in the kit?

Thanks you have been great with your communication on the site here. :)

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.

Yes, anything you can do to improve airflow will help flow and temps.

Ya I would be interested in seeing those too.

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 ??
