Preventing Turbo Whistle Noise

I can kinda relate. Today I was driving up a steep grade with 44 in the box listening to the engine turbo sing better than any opera singer..iv ever heard
I got goosebumps listing to the turbo ..

 

I have straight pipes on my 96 cat, and all when it is pulling all you hear is the throaty engine noise, the only time you hear the turbo whine is when I let off to shift.

 

I like the one where he is sipping coffee out of a coffee mug while going down the road. That's got disaster written all over it.

 

What is wrong with drinking coffee while driving.

 

i drink coffee while driving every day....lol

Probly thinking of this guy?

 

To stop hearing the turbo whistle look into helmholtz resonators, and get ready to do math.

Put a proper sized one on the intake and the noise will go away.

 

No I mean he was drinking out of a mug like you'd use in a restaurant, while he is moving. I drink coffee too while driving but out of a Stanley mini thermos.

 

The turbo noise has a lot to do with the compressor wheel. Some are noisier than others but they can be swapped out. This is common on the little trucks to get a little better performance out of the turbo.
