Jim Posted June 25, 2006 Share Posted June 25, 2006 When turning my car off i can hear the turbo spinning down to a stop. (like on the big bb turbo's)..sound goes on for a fair few seconds the reason i ask is a friend of mine also has a highflow turbo but his does not do this.....maybe his is not bb?? anyone else have this? cheers ...Jim Link to comment https://www.sau.com.au/forums/topic/123717-q-for-those-with-a-highflow-rb25-turbo/ Share on other sites More sharing options...
R31Nismoid Posted June 25, 2006 Share Posted June 25, 2006 One of you had a pod and the other doesnt? Generally thats a good reason. If you have a airbox or enclosed pod the sound is not very audible. If thats not the case, your friend probably doesnt have a Ball Bearing turbo. No great drama...

Bass Junky Posted June 26, 2006 Share Posted June 26, 2006 BezerkR32 ALL R32 - R34 turbos are Ball Bearing. 100% The noise is not to worry about, mine makes it. I love it! But it has often got me thinking that noise means things are touching each other..... What are my wheels touching, or it it simply the sound of the bearings turning which is then amplified/resonated by the compressor/turbine wheels?

skylinecouple Posted June 26, 2006 Share Posted June 26, 2006 Had my hi-flow for 2 years at 1 bar with standard air box and k& n panel. Never had any noises after turn off.Oh,......there was that time the engine fell on the ground,but that was more of a clunk than a turbo whine.

The Mafia Posted June 26, 2006 Share Posted June 26, 2006 well, I have a Garrett GT30 with a 4 inch intake, through a 90mm AFM to a big motherf**ker assed pod. Anyone want to hear it spool? Also, takes about 30 seconds to nearly a minute to completely spin down with that metalic noise after the engine has been turned off.
