Just so you can read it again. ^^^^Since there are alot of turbo issues with the 6.7 if you remove the silencer ring you will also be voiding the warranty on the turbo. If you can afford a couple grand for a new turbo go ahead and remove it. Dyno results have show a 25 to 40 HP LOSS when the ring was removed. It is more than just a silencer, it actually helps direct the air into the turbo.
Couldnt you just say when the turbo "let go" that all the turbo housing and pieces flew apart even the ring?DO NOT remove it, my gfs uncle works in the turbo lab at cummins. He gave me a good reason somethin bout direction of air, and to keep the turbo from surging, and mainly to keep it in one piece. he showed me pieces of turbos where the ring was removed, it looked like someone straped a stick of tnt to it.
Alright, I was thinking that plastic/foam deal was the silencer ring because it also directs the airflow and quiets the whistle. Maybe somebody else knows what it's called.Mine was a metal chamfered ring pressed in the intake side with an extension toward the compressor turbine
