Got Er Done . . .
I agree, an easy Mod. Did it in 20 min w/ a dremel tool. We'll see how effective it is now that we have open air. I also don't think H2O is problem as with the stock it i the Blue fiber and w/ Airaid it is an oil soaked filter so H2O shouldn't be an issue as to penetration through them.

One thing you guys have to remember about compressors (a turbo is a compressor) the suction pressure is directly related to the performance of the compressor, the compression ratio, and the final discharge pressure. More than likely what the gain of this mod is in traffic you are using more dense air charge, due to it being ambient, and not whats in the engine compartment. The ram air would be allowing your turbo to react quicker because it will have positive pressure coming into it, not vacuum, thus allowing it to operate more efficiently. The turbo will only boost exactly as you mention, what ever it calls for, how easily it acheives this is where the minimal performance gain comes in. It also makes the effiency of the intercooler better by the charge air coming in at ambient, which would explain the drop in EGT after letting off the throttle.

ahhhhhh... grasshopper! the cooler the air the more dense....so therfore better combustion. or complete combustion... you have enlightened me! makes sense. if you start with cooler more dense air,,,the better the turbo does at compressing it. i would have to say that this mod is worth it. might cause more filter clogging but thats a trade off you would have to decide

Hey Ryan, Your the first person I've run accross that believes it makes a differance pushing air into a turbo! I once had a fellow tell me it was a waste to have ram air on a diesel. It already has it and its called a turbo. Super dutys are easy to go one more step. Cut the hole in the core support 4" round and use PVC pipe and fittings into the air box. The next step is a 3' to 4" rubber adapter and a 4" 45 degree elbow to make it 4" all the way to the turbo. The plastic pipe doesn't conduct heat like aluminum or steel but is way smoother than rubber.

Ramsmoker, mrxlh is right, he just might not be getting it across the best way. While the stock engine only allows so much boost, dont equate boost to mass of air entering the engine. An inititial colder dose will be more dense so after it is compressed up to XX PSI it will still have more mass.
I agree the gains are probably small but, this is the best mod on a $ for hp gain ratio. Even if it worth only 3-5 Hp think of the 3 cents you spent on tool wear and electricity to do the mod.

It's really about the temperature--bottom line. It's actually possible (I've seen the data logger) that the second intake air sensor CAN give a cooler reading than the first intake air sensor if the available air charge is there. THIS IS NOT TYPICAL nor should you ever expect it in the real world. If you go to the Kennebell website and read some of their research about "cold air intakes" and what their research has shown then you know why they will only honor warranty when their kits are used with the factory air induction. Check it out--good reading on forced air induction (supercharger/turbocharger).

Don't u think the filter itself is a little denser than an oil soaked rag . . .

Well, I went ahead with this mod. I read somewhere about someone making a damper out of a VHS cover and choke cable. I made one out of 316 SS painted to match with cable going into cab. Since this truck came with the K&N open style filter, I figure that giving the unit fresh cool air, instead of pulling air from around the motor/Radiator would benefit. Mucho power? Ungodly results? Probably not, but since I like to tinker, and giving the engine cool air vs the air heated from the rad/motor seems to make sense, why not.
