i recently installed a new turbo inlet hose an now my cars turbo sounds different. it makes a higher pitch winding sound. also, my bov doesnt let the air out like it used to. now it kind of flutters. anyone know y its doing this?
thanks

 

with a new inlet hose.....the sound of the turbo spooling is more apparent...nothing to be concern with.....as for your bov...is it stock?

the diaghram spring could be week

 

no its aftermarket. an my turbo's spooling sound, sounds like there is a leak. my vacum is 2lbs lower than it used to be.

 

are you sure you tighted up everything super tight?

 

ya, theres not much to the inlet hose, just to the turbo, the intake, an the hose that goes to the i/c. i pluged in all the vacum hoses to. im thinkin its a gasket from the up pipe. also, i was thinking that, since i cut my muffler there is no back pressure that the wastegate isnt working properly.
