Cowl air intake.

[thx997303]

I built an intake similar to the hypermax intake today. Man, what a difference. Better throttle response, feels like more power.

But man, cutting the hole for it was a pain. I cut a 4" hole to the passenger side of the brake booster with a hole saw. Darn spot is not flat.

Anyway, used a dryer vent tube and a 90* elbow. Works great.

This should be done to all of these trucks in my opinion.

Pics?

Well here's the hole in the firewall.

And here's the coupler I used placed in the hole.

I'll post a pic of the completed thing when I take one.

And here it is, in all it's ugly splendor.

I think I'll replace the aluminum pipe with plastic, but I had this lying around. I also intend to seal up the whole thing with HVAC aluminum tape. Should work nicely.

Also, I gotta figure out why my pictures always come out blurry. Hopefully I have that fixed.

hmmmm wondering why is this a better set up for the intake? im curious

 

[kc0stp]

Cold (outside) + pressurized air vs hot (engine bay) + static air

 

[icanfixall]

Air pressure builds up off the windshield so its forced into the intake. This is an old drag racer and NASCAR trick from many years ago. EVERY NASCAR intake is designed this way. Watch for it next time you watch a race or see the hood off a car in the pits.

ok, i can see the advantage, never really thought of that

Still has that nice cast aluminum air preheater like mine, workin on a setup to get rid of that on mine then may resort to pulling factory turbo since I was unable to remove 2 of the outlet bolts to go 3in flange to dp.

 

[thx997303]

Yeah, I'm still thinking about how to get rid of that massive thing. Maybe some sort of inline cone filter, and a silicone elbow to the turbo to isolate the heat.

Maybe something like this K&N shapewise, bolted between two flanges.

I wonder about this one too. Seems to be for a 5.4 L F150
