I had my new VF34 turbo fitted and mapped and yesterday i noticed when i rev the engine I can hear the turbo spin up and down as well.

The turbo was purchased from a member on here as NEW and didn't notice any play in the shaft.

Any ideas what this is!?

 

i have the same got one new from someone who is on here .

 

they are a roller bearing turbo and some noise is perfectly normal

 

As above it's normal, cracking turbo wish I never sold mine, you get used to the whine and then learn how to make it whine like a b!tch.

who's selling new ones and how much for?

 

My VF22 also makes a whine, sounds like a dam supercharger.

No issues at all with it, think its just the sound of the roller bearing turbos
