Peninsular makes a different upper intake...I have one in the basement somewhere....makes it easier to run an ATA IC I suppose (I just modified my upper to work)...

One member was talking about building a complete intake assembly from the intake runners up. Leo

May I know why you want to mod your intake?
The reason you cannot google is because it is not the most common mod for 6.5. Unless intercooler mod or "S" vin mod to "F". I am not sure if there is any performance gain from it. If there is, I have not seen anybody did a write up about it.

i was thinking that if you could find one with better air flow it would let the engine breath easier. As it does in a gasser.

Are you talking about air intake or intake manifold?

Changing the intake won't do anything. You have a 3500 which means you probably already have a "F"(non egr). Not the same as gasser. These engines are turbo charged. Changing the waste gate will do more than any intake swap.

Like Aces said, we're turbo'd, which means constant pressure. I would think some gains could be had by gasket matching and some port work. Not much gains, but some.

IF by chance you are talking about the entire intake manifold, I am currently making one like NVW said. Once it is done I will post a thread on it here, and any results.

My first diesel!
My profession tells me that a smooth wall and rounded corners will flow better than the "bumps" left from casting and the hard corners at the transition from the upper plenum to the intake manifold. Laminar flow vs. Turbulent flow. Might make some difference.

I've called a couple of diesel shops by me (ford no less) and the guy told me flat out, polishing does make a difference. Remove any and all imperfections, he said. Again, not sure just how much benefits we'll see.

Iv'e talked to a couple myself and they said the same thing. But none of them would say if spending the money would see any increase of horsepower.So i think i've answered my ? on this one.
