whistling turbo

[letemlaf]

my turbo when under very slight acceleration will make a whistling sound.

sounds like a person whistling or something.

has anyone else got that?

on the weekend i changed back to a standard bov because the other wasnt working correctly, so now the intake sounds from the pod sound completely different too.

thats not a problem is it?

not sure if it it the same thing that i had, but after 2 weeks having this whitsle now it is really bad and i am buying a new turbo. you might just have somesort of air leak though, just get it checked out by a mechanic.

depends what pod filter you have, some make a slight whistle at about -0.4bar, due to turbulence. the stock bov does actually change the induction noise the pod filter makes, perfectly normal. It will be more distinct with the stock bov.

my turbo whistle is much louder since i got the dump pipe done

i like it

when i got the exhuast done on mine with the dumpy it whistled and then when the pod went on you could really hear loud sucking and you could still hear the sucking although not as loud when in vacuum...

i would think its normal, if your worried go get the car checked out to ease your worries

I miss my loud whistle from the stock turbo since changing to a GT2535,it's for a good cause thou!!

when you have an impellor that's spinning at like 10,000rpm then its going to make a whistle

[Parag0n]

Isn't it more like 150,000 RPM lol ?

Isn't it more like 150,000 RPM lol ?

right on the money

The Stock turbos go between 80,000 and 120,000 rpm... hence the idling required before you shut the motor off to feed them oil while the spin down to a low enough speed.

The whistle is normal. Mine whistles, and apparently its the air going throught the air flow meter wires, or the turbo sucking in all that nice air.

If you open the intake up, and the dump pipes the turbo is going to get more air, hence the whistling. So stop panicing dude, its just air noise. Learn to love it.. Cause I absolutely love that noise... You know the bitch is working
