could anyone give me an example of a turbo bark???
i really don't think i have heard one yet, but when i kill the engine sometimes it sounds like a ****** off bird churping or maybe barking??
will it hurt the turbo?

 

It really does sound like a dog barking. You'll hear "woofwoofwoof" when you jump off the accelerator at high boost.

If you do it a lot you can hurt the turbo. Just ease off the gas at high boost levels unless it's an emergency and you will never have a problem.

The chirp you hear is the belt, it's caused by the high compression engine stopping instantly and the accessories trying to drive the belt.

 

Funny even with my TST on 7/7, I only barked my stocker once...

But with this Sledpuller66, I have barked it like 10 times now on accident... When the TST feels you lift even slightly fast, the fuel is cut back quick, and whoops, barky,barky

FWIW

PS - and trust me, just like my first turbo bark, you will be like, OHHH.... THATS what it sounds like!!!

 

I second what Tomeygun said. If you have a boost gauge will drop some the jump back up a couple psi and keep doing this cycling until it is at 0 boost

 

What you are hearing "CHIRPING" upon shutdown is the serpentine belt when all that power comes to an abrupt halt. Perfectly normal. When I bought my truck, there was a yellow tag on the cig lighter stating to expect the "Chirp" upon shutdown.

Others were concerned about the chirp and replaced their belts with a "GatorBack" from Goodyear (I beleive that to be the source). Mine chirpped for about 3 -5k constantly. Once in a long while it might do it, but I never pay attention to it anymore.

 

thanks for the input
i guess i haven't experienced it yet
hopefully when i get the new turbo and injectors i won't have that prob.
