For the most part correct …
Diesel’s do not have throttle plates … However … depended on how much boost and the size of the turbo you are running, you may want to use a blow off valve or a pressure release valve to decrese turbo shaft damage from surging. Im sure you are all familair with turbo surge …
On a diesel motor … If all that boost is suddenly shut down (powershifting, heavy throttle lift, etc …) that boost has no where to go, but back threw the turbo itself, and out of the air box. This is turbo surge or more commenly known as “turbo bark” in the diesel world. It will let out a “woof woof woof woof” sound that decends from loud to quieter. The charger on my truck will surge pretty easy now if I let it … (with more tuning I am now pushing 50psi) … But I can drive around it more or less … I try not to let off quickly and I can shift fast without it surging. But if I am running it hard and into heavy boost (30psi+) and a car or something pulls in front of me … It will surge. Any other questions please feel free to ask.
