possible turbo noise?

[dtballer]

I have recently noticed that after i accelerate hard and then let off the gas the engine makes like a deep swoosh sound than kind of pop or clank its hard to explain the noise.I have no acceleration problems and I only hear it when i let off the gas pedal. Any ideas??

[dtballer]

Here are a couple videos that i took to try and capture the noise my and ideas whats up with my truck. Turbo is stock after market intake and exhaust. Any and all help is muchly appreciated. The first video where i am not moving i am in gear thats when it makes the noise if im in park you do not hear it much.

Vid 1 and 3 are just normal noises, its just excess air pressure in the intake system between the turbo and the engine. The noise is just the extra pressure releasing back through the turbo, like i said, completely normal, nothing to worry about.

The 2nd vid, i noticed some surge, thats the rapid ch-ch-ch-ch-ch noise when accelerating. That can potentially damage a turbo if it happens a lot. There are cures for that. The cheapest is to get what most call a wicked wheel, its just a different designed compressor wheel. That will cure surge most of the time. Some times it wont though, and in which case the only other way to cure it is to get a ported intake housing.

A wicked wheel costs about $60 from xtremediesel, and a ported housing is about $450.

Hey dtballer, I had the same problem. I have just dealt with it for two years and I finally got sick of it. This morning I installed the wicked wheel. I am happy with it now, no turbo surge and the whistle at higher RPM's is sweet. You will be happy with that.
When you install, look around for the eaiser install instructions. The directions tell you to take the entire turbo out of the truck but you do not have to. I changed mine out with only taking off the compressor housing, all you need is a compressor and impact gun. This saved me a couple of hours and a lot of headaches. Good luck.
