Turbo stopped whistling
 

Well i know this sounds weird but up until a few nights ago my turbo made the normal whistling sound when it started boosting. After my wastegate line came apart and my turbo boosted 15psi it no longer makes this noise i fixed the line and the turbo boosts fine with no screeching noises but it doesn't sound the same anymore. any ideas, oh and its a t25 i know its small, i've got a t3 48. 60. waiting to be installed so i'm not too concerned i just thought it was odd.

Re: Turbo stopped whistling
 

maybe you fucked your engine and it doesn't spool the turbo as well anymore

Re: Turbo stopped whistling
 

nah it boosts just fine no oil burning nothing it just doesnt whistle anymore

Re: Turbo stopped whistling
 

does that have the adjustable nut on the wastegate? if it does you might have set it lower or somthin. im wingin it here weird prob, hope you figure it out.

Re: Turbo stopped whistling
 

no its not adjustable i did however raise the boost yesterday with no affect on the whistling of the turbo. i thought that maybe the blades of the turbo had become dirty or something maybe changing the pitch but i cleaned them yesterday with no luck i'm stumped here

Re: Turbo stopped whistling
 

did you do anything with the air filter setup since the last time it made this sound?

Re: Turbo stopped whistling
 

Why not get someone to step on the gas and you listen to where the noise is coming from?

Re: Turbo stopped whistling
 

i think thats the problem. there is no noise, the turbo lost its spooling noise. i almost thinking that it might be an air issue

Re: Turbo stopped whistling
 

if it boosts the same its fine
you might have actually fixed it :P

Re: Turbo stopped whistling
 

no cause i have a t25 and it screams when spoolin.i have mine on 13 psi and the sounds is sweet

Re: Turbo stopped whistling
 

go buy a new Turbo whistler :S

Re: Turbo stopped whistling
 

lol, did any liquid go up your charge pipe? maybe it coated it or something, you could always buy a new turbo (bigger) ;D

Re: Turbo stopped whistling
 

It couldn't think of anything else to whistle to.

Re: Turbo stopped whistling
 

its probably just not happy anymore. you need to do what makes your turbo happy... just like the little VW Fast guy says

Re: Turbo stopped whistling
 

Who cares its only a T25 :-\
This is an obvious sign that you need to uprgrade

Re: Turbo stopped whistling
 

yeah like buy it some flowers, tell it that it looks pretty today, you know that kind of stuff ::)

Re: Turbo stopped whistling
 

yeah no ---- read up top i have a t3 .48/.60 waiting to go in i just moved and need to get my ---- together. i was just curious if this had happened to anyone else thats all

Re: Turbo stopped whistling
 

Mabe you overspun the turbo and cooked a little of the bearings in it? Now you have like .00000001 more clearnace in the center of the turbo, so it sounds a little different.

Re: Turbo stopped whistling
 

(dont qoute me) iv been told the whistle is the turbo vibrating when it spools at higher rpm, maybe just maybe something happend and it got perfectaly balnced and now it bearly vibrates
