Strange sound on Boost.

[chief]

his has just happened today and i'm a little concerned about it.

When the car is on load and the turbo is spooling up not only do i have the normal whistling sound of spool up i also have a really sound of something that sounds like an air leak or someone letting down a car tyre.

Really confused as there;

is no smoke.

Seems to be constant boost

Doesnt appear to be slower " could be wrong"

Cannot locate any holes on any of the visible pipes and nothing seems to be off.

Car is an EP91 Glanza and bog standard under the hood.

Just concerned and want to get this sorted before something happens - was worried i have a fooked turbo blade or something....

Doesnt sound like a blowing exhaust either.

sounds liek an air leak. youll have to check all the hoses etc to find it.

dont worry though, it isnt fucked. its a simple fix, you just need to locate it.

This happened to me too after fiddling about i found there was a leak in a vacum hose going to my turbo timer . So i would say u have a leaky hose somewhere
