I didn't change the intake
it's still stock air box

the whistle noise sounds like a vacum machine sucking up air instead of bov letting air out

 

DUDE! I didn't even think about this, the WR makes a high pitched whistle and is particularly noisy when moving air at higer rpms

 

I guarantee you installed the turbo to lower intercooler pipe gasket upside down.....

10 to 1 odds

 

or you have a bad turbo, sell it to me for 500 bucks and get out while you can!!!!



















[disclaimer:ON]tis a joke, not saying FP is selling bad turbos[/disclaimer:OFF]

 

the whistle start when boost start
at 1 psi

 

I have the helix lower IC pipe
there is no gasket in between

 

then there is the problem...you can't have medal bolt to medal like that with no gasket.....

did you have it like that before the turbo install?

 

the stock tubo didn't have a gaskiet on the outlet to the lower IC pipe

yes I can hear the stock turbo spool when I pay very very close attention
but the white rabbit sounds 10x louder

 

ok, im talking about where the compressor side of the turbo bolts to the pipe....is that the same thing you are talking about?

Ive never replaced my lower intercooler piping, so i don't know what upgraded ones come with....does the helix one come with a new pipe that bolts directly to the turbo?

 

yes we are on the same track
I double checked my old turbo and pipe
it just bolts up without gasket

 

well, there should be a gasket there. If its the stock hard pipe coming off the turbo then there should DEF be a gasket there.

i don't see how helix could make a pipe that wouldn't need a gasket there either(if they even replace that piece).

did you unbolt that pipe from the turbo when you replaced your lower intercooler piping, and bolt it back to the stock turbo...or did you do the lower IC piping with the new turbo?

 

What psi r u boosting? I had the same noise with another turbo upgrade. I swap to a stiffer spring in my Forge bov then the noise went away. Maybe your bov can't handle the higher boost with the WR.

 

he said it starts making that noise at 1psi, doesn't sound like a faulty BOV to me.

 

My bad, you're right, if it start at 1 psi then maybe some line is leaking or WR's tail is wagging. LOL...

 

I was wondering the same thing
but the lower Ic never taken off of the Stock turbo until this morning
from factory there is no gasket
