I got my Hypermax kit installed!
I went over to a friends house since his garage is big enough to get my truck out of the rain and installed my Hypermax cowl induction kit. So far I like it, my cruising egt's are down 150*, I get to hear the turbo a little better and it makes a cool sucking noise when I punch the throttle. It will be another week before I can see if my mpg improves any.

It pulls in cooler outside air from the cowl area, same place your heat-A/C gets air from. It's supposed to help lower egt's and possibly improve economy. The only problems with the setup is the pain of cutting a hole in the firewall. It's also suggested to disconnect the hose if you have to drive in heavy rain and if you get a heavy snow, make sure to brush the snow off the cowl panel so the engine can get air.
I think they make a kit like this for the N/A trucks as well.

I have the same setup, and that sucking sound was a huge surprise for me. I've gotten used to it for the most part, but I would rather it were gone. I keep meaning to fab up a 4" T fitting to allow me to run the Hypermax and the Ford cold air intake.
The next question I have is about the ATS/Ford filter set-up. Does anyone know if performance improves by moving to a really big cone element?

Now I'm curious that doesn't look like it would get as much air as a modified front air intake. Is there a drain in there somewhere it looks like it routs water straight to the motor when the pickup is parked.

It moves more air, I can't say exactly how much, but I also noticed lower EGT with the Hypermax cowl intake.

My cowl drains are functioning and I have the drain hole in the airbox, so I'm not worried about water getting into the motor.
I kind of wish this kit made more noise, it's definitely noticeable, but if I turn the radio on low volume I can't hear the sucking/turbo noise any more. I like to open the rear slider just to hear my exhaust better, nothing quite as cool as an engine performing it's function.

If you really want it louder, I suppose you could cut another hole in the interior side of the firewall and have it pull air straight from the cab...

Seeing as the turbo airbox hooks up to the stock ford intake hose, shouldn't this work on N/A trucks as is? Shouldn't be any difference that I can think of....

The area at the base of the windshield is a high pressure area.
Not as much high pressure as the front of the truck, but still better than under the hood for both lower heat and higher pressure.
On a NA engine, either the front or cowl area are better than under the hood, every possible PSI of intake air pressure is better than less.
looking at that system, I think blowing snow could cake the filter just like it does with my front ram air, and if that happens your engine will stall from lack of air when the filter ices over.
If you have trees where you park your truck, watch the cowl drains don't get blocked.
Water into the engine would be bad news.

I cranked a case tractor, or tried to that had a gasket out on the air intake after it had been raining a couple days. Water probably shot out 10 feet from the headgasket, it wasn't a good day.

hey a cowl induction setup.nice!
they've done studies vs ram air,and this setup is actually more effective unless your speeding.
i like!!!
edit,
dang.i must have read this back along in hot rod mags etc.
oddly a quick search on the net isn't finding much.
i'll check into this more and post some stuff latter tho,less others beat me to it.
