Turbo Noises
Well fellas I was playing around a little why'll ago and i stomped on the truck and it overboosted like 80# and ever since it makes a siren noise that is coming from the turbo. I took it to the dealer and they checked turbo for carbon build up and found none.They also cleaned the EGR and decooked the turbo what ever that means.The sound is still there.I am loosing nothing as far as performance and I Checked myself and there is no play in the turbo shaft at all and I cannot find no intercooler leakes. Does anybody have any advise?

Maybe You Just Broke it in :)
|
what boost#'s do you have now, normal?
|
Same as before no problems other than siren noise.:su:
|
Where are all the 6.0 guys, some one has an idea.
|
Is it using any coolant?
|
He said nothing has changed in performance, and it is not using coolant.
|
Yeah I had what sounds like a similar problem with my 04' work truck but mine was going thru coolant.

I have a performance wheel and housing on mine and have never seen more than 42psi.
If it boosted to 80psi either the vains were sticking and all of a sudden unstuck or your bearings are toast. Make sure it has no play front to back because it could and the wheel could be touching the housing and causing this siren noise...ask me how i know:poak:

iracemx6 There is no play in my turbo shaft at all. All the mods you have on your truck as far as injectors(what size) and turbo are the way I'm thinking of going. How does your truck run and what kind of price are you looking at. Did you stud your truck?
