Aww come on, half of us know that you have a 6.0 intake installed already.
Show us some pics!

 

Here are the dyno results I was talking about comparing a cold-air intake (AFE Stage 2) to the 6637 (called "Tymar"), and no filter at all ("open element"). Pretty interesting numbers:

 

I really, really don't want to start pulling worms up outta Clux's can, but please allow me to make one comment, and then hope y'all will go search the old threads that cover this in richly satisfying detail:

What is missing from this thought experiment is boost. A naturally aspirated engine hoovers up whatever it can get; cooler air will indeed make a difference. A turbo packing in 25 psi or so has a vastly greater impact on density. (pun intended ) More boost is not more power in a linear relationship, there are diminishing returns. And the heating by compression/cooling via the IC adds numbing complexity. Somewhere in the midst of all that the impact of the original ambient temp is drowned out by bigger factors related to boost. HTH.

 

I thought I read somewhere the 6.0 intake was good up to around 400 hp then became restrictive? Am I remembering wrong?

 

I guess we'll find out...

 

I apologize if I've stirred up trouble. I'm trying to think this through for myself as well. Logic tells me that engines love cool air. I picture our trucks climbing a long, steep grade and towing 5-10K lbs, a 1000 lb iron engine circulating 15 qts of hot oil, a couple of large cast iron exhaust manifold getting up to 1200 degrees, and a big, cherry red turbo to top it all off. That engine bay has got to be hot (certainly hotter than running a couple of dyno pulls), and I'm thinking it prefers cool, clean air over warm/hot, clean air.

Granted, a highly modded engine that makes more than twice the intended stock horsepower is going to need a lot more air, but I suspect it would still benefit from getting that same increased volume of air at a cooler temperature. If we're comparing apples to apples, we'd see a dyno run comparing the Tymar filter as normally installed versus enclosed for cool air.

At that point, the AIS wasn't engineered to supply air to a 500 hp engine, so if you're lucky enough to make that kind of power, you need a freer flowing intake for sure.

Sorry again for stirring the pot. This stuff is fun to think about, isn't it? I'll go back to lurking...

 

You're not the first or the last........................

I run on dirt much more than I'm on pavement. A lot of these pickups never get off the pavement so it's not so much a consideration, but for me having the intake pull air from up front is as much about getting clean air as it is about getting cold air.

 

"the IC adds numbing complexity" I don't know why, since the IC does add to the equation, but I found your choice of words refreshingly funny.

A great point! Dynos are one thing, but real world application is another. I venture to say many dyno runs are done with engines not fully up to operating temperature. I sure wish someone had real world underhood temps while pulling a 7000 lb travel trailer up a 10 mile, 10% grade with OATs in the 90's.
Yep, for me cool & clean is how I want to protect my investment.
