Epic turbo noise..turbine

[travisreeve]

Hi guys.. I have a 20vt in my mk1 golf AGU k03 turbo.

When i boot it the turbo spools up and then seems to make an epic turbine kinda sound pretty dam loud aswell. Im taking it this is a problem the car seems to be boosting okay but i have no gauge to confirm this and some times in 4th 5th at low revs the car seem to want to judder

Any thoughts on this would be appreciated

I would love to mate but i really dont wanna risk it if its something bad.. Best way to describe it is it sounds like a turbine of a plane aha

What intake you running ?? A cone filter will make the turbine louder.. if enclosed intake you shouldn't really hear much.. You checked for boost leaks ?? and correct boost ??

Could be a turbo bearing

Think he means he doesn't want to risk running the car to take a video mate.

remove the TIP and see if the shaft has any movement. a little movement up and down and side to side is fine movement in and out is not

Is the noise on boost or as you come off?
