gtx2863R whistling
 

hi
I just installed my brand new gtx2863r and what's different from my previous T3/T4 turbo is the whistling sound the turbo makes.

is it normal ?

Did you happen to drive by attractive women? A wolf whistling turbo would pull a premium one week before Race Wars.

Re: gtx2863R whistling
 

Yes. Due to the anti-surge ported shroud compressor cover

Re: gtx2863R whistling
 

Anti surge?

Not that piece of sh!t housing in the 2nd picture.

This is a real port-shroud anti-surge housing.

This is what your housing looks like, right, alperx?

The map-width enhancement groove of the housing is what's causing your whistling.http://img.photobucket.com/albums/v2...T3076RMAP2.jpg

Anti surge turbos whistle/make a high pitched sound above certain pressure ratios. It's perfectly normal

They really dont start to sing until 20+ psi

I drove a big diesel box truck with an s400g with a ported shroud that ran 40-45psi... sounded so sexy

Re: gtx2863R whistling
 

I understand the difference, I was just merely showing a couple examples. It is easily searched that the drilled shroud isn't in the same ball park... anyways, I only use Garrett's to begin with. Starting to get the bitter bug of old age are we? Haha!

If you mean my knee aches every time it rains, or I'm taking more supplements than food, yeah.. :scared:

You know you're old when you open your cabinet and the first thing you see is your Metamucil.

Re: gtx2863R whistling
 

No, you know you are old when you reach for the cabinet that has your Metamucil and instead have to turn and hurry off to the restroom.
