If your only purpose for an intake is to create more power, then knock yourself out - go for it!

Good luck doing that sucking in hot under-hood air.

I like my intake to do everything the vehicle manufacturer intended - and more.

Whatever turns your crank, dude.

I never said they were great, I just asked if you ever considered why they were there. Some are good, some suck, but they all do two things: provide the most possible efficiency for the flow they do allow in terms of cooling the intake and protecting the intake from FOD, most notably water ingestion.

I suggest you just install the BHAF any way you like and be done with it.

i did read the whole thing ... mainly because I could not beleive you brought physics into a bhaf air filter thread .

Just to throw some more wood on the fire, I'll bet you that your airfilter with your chioce of air box will make less power then my intake pipe with no filter on it

You would absolutely win that bet. But let's not debate the merits of doing it one way or the other, how much difference it would make, or if it was worth it one way or the other, depending on your goals for the truck.

BTW, here's some pics of my 1st Gen's BHAF. It's a filter commonly used on the NASCAR circuit, WIX 46433, 625CFM:

cooler air going through the turbo would be better bc its more dense and would be even more dense when compressed, air going to a turbo charger is the same concept as going into a naturally aspirated engine

I understand your "theory".. but the fact is, the turbo will superheat the air anyways. It doesn't matter if the "cold air intake" makes the air temps 5 or even 10* cooler. The turbo heats it right up anyways.

I don't know about you, but my turbo runs boost around 5-7psi cruising down the highway. It's not "superheating" anything under those normal conditions. Even under max boost, the air coming out of it to the intercooler is still the same number of degrees cooler relatively speaking, as it was going in + the compression factor as I already explained.

Sorry you don't get it 85_305.

Why don't you just admit you're wrong for saying intake air temperature doesn't matter, so we can leave this on the dead thread pile and get on with it?

So just because you are only boosting 5-7 psi cruising down the road your turbo isn't hot? Please tell me that isn't what you are trying to say. What pushes the turbo? The EXHAUST. 5-600* cruising-temperature exhaust. 1200+* wot/towing exhaust. Not cool by ANY stretch of the imagination.

Yes, the intercooler cools the intake charge.. hence the name inter+cooler.
