Your first post on this forum, and we get this huh??

Simple Google search will yield this and similar

Turbo Resonator
The turbo resonator is a muffler that slightly reduces the high-pitched noise that comes from the turbocharger, often referred to as turbo whine. It can also change the tone of the noise to make it sound deeper and more appealing. Most turbo resonators are simple, inexpensive and lightweight units that can be quickly installed with a few basic tools. They are often fitted as standard equipment on new turbo-powered vehicles, and can be bought from stores that sell automotive parts. Resonators are made from either plastic, aluminum, stainless steel or carbon fiber. While the plastic models are popular because they are the least expensive, they need to be checked regularly for signs of cracking.

Maybe you never saw a silencer ring either?

Both items are installed by manufacturer to quiet the diesel.

I kinda like turbo whine myself but you won't hear a stock 6.7 Powerstroke make it.

First off, I'm a n00b to this forum but NOT to diesel trucks. I am simply here asking a question from the DARK SIDE (Cummins group), because I am looking into getting a new truck and am considering buying a 6.7L Powerstroke because I find the new V8 very impressive relative to how the previous Navistar/International built Powerstroke engines were behaving.

Now, my random question for all of you 6.7L Powerstroke people is:

What is the "turbo intake tube resonator" that I see being removed with the installation of virtually any cold air intake system available for the 6.7L, and what does it do? I am referring to that big black plastic thingy (for lack of a better term) that sits pretty much in the middle on top of the engine and holds some of the coolant lines down. Yes, I know, the answer to this may seem obvious, but I still thought I would double check to make sure what this does, and what the effect of removing it would be.

Thanks in advance!

I guess the answer to the last part of your question, is that by removing the turbo intake resonator, it will make your turbo a bit louder.

When i was completely stock and just installed my S&B cold air intake, it made my turbo louder :thumb:

I just posted a video of what my S&B Intake sounds like. Go to my channel on youtube. nvhayfarmer1

 

Thanks very much!

 

One more question in regards to the turbo setup:

When I look at the turbocharger system on these trucks, I notice that the turbo has two cold air inlets for the single shaft sequential turbo, but only one of them (the top one) seems to hook up to the air filter and intake assembly. Where does the other turbo inlet (the lower one) receive air from?

Here are pictures of what I am talking about:

they both come off the filter.
