CFM + and more

[trbo dsl]

Sorry to kill (or at least injure) multiple birds with this stone, but please bear with me…
While looking through the “archives” for any info on Air Intake kits and the new 7.3L CFM+ manifold, I came across the 6.0 to 7.3 IC swap. Looked simple enough and made sense, until it came to the “de-foil” mod. So I read how to do it as well, and sure enough, It is just how it sounds… “de-foil”.
But why? Is it to radiate more heat prior to going into the IC?
Second question was actually the first. Anyone ever use, or find any useful information on the CFM+ manifold?
Finally, has anyone ever seen real dyno numbers to justify doubling the price between a stage 1 and stage 2 air intakes (afe)?

It looks better and gives a bit more sound... There is NO heat benifit to it, it was not added for heat issues, only for sound.

what he said

pure work for looks
to give an idea have a look at an early99 engine , they came with no foil .
mine may show up in the gallery pic i have

I took the foil off and can say I didn't really notice any type of noise difference, but the pipe looks way awesome.

There is an interesting point there. The foil could kep heat in or keep engine heat out. It would be interesting to know what differences the mod makes in air temp in the tube.

I hear a lot about EGT and before I ask a real stupid question about it I am going to do a lot of reading. That being said I am going to look around for an air inlet temp gauge which I think would be equally important, as far as hosepower goes anyways.
I would like to get some sort of reading before and after the 6.0L Ic swap. Because as I'm sure everyone knows, for every 10 degrees of air inlet temp you drop, you gain 1% hp. Now obviously this is not exact, like most automotive formulas (concerning horsepower). However, it is very close.

Dont waste your time with the 6.0 cooler, you will see little if any benifit from it.

The Insulation was added for ONE reason, and ONE reason only... SOUND.

The Hot side IC pipe can see temps of 400, your engine bay does not get over 200 at worst...

ITS FOR SOUND PEOPLE...

i took my foil off and it did seem to whistle a bit more, i also took the other IC pipe off that is returning the cold air and wrapped it with high temp header wrap. Im not sure this has helped but it made sense to me.

Yeah man i really doubt it made that much of a differencebut i've been wrong before.

So there is no reason to put a 6.0 IC on ???
