D Turbo

[SCSG-G4]

The new C- turbos are not really loud whistlers like the old ones. Can hardly tell the difference. Maybe it will be louder when it loosens up a bit but as of now it’s not that bad.

If you don't have the two types side by side for a comparison I'll go with a natural loss of hearing due to age (whether the loss is in the turbo or the listener remains to be determined).

I'm just thinking about all the posts I've read here in the past about everyone and their dog wanting a whistler turbo. Look how far we've come

I guess I've never experienced a loud turbo. The turbo that came with the Cat 3116 in my deuce has a pleasant whine to it, but definitely not deafening. It might have to do with the muffler too

I was thinking the same thing. Everybody just had to have the C turbo years ago, and 20 years ago when I got mine with the D turbo, I kept think just how nice that sounded and that I definitely didn't want anything louder.

For "light" work and parades it's hard to beat that whistle in a low boost low rpm situation, After the C is spooled and building boost though, it's hard to hear the engine under it, for me anyway. I want to try a D after the inevitable happens and the C quits just to see what "quiet" is like. If you ever have the muffler off of the A3 and it's safe to do so, start it. You'll either love it, hate it, or learn to hate it .

Well now that I’ve had the opportunity to drive it with both, I prefer the D. I’m going to try to rebuild my D and if all goes well may reinstall it.
