Q For Those With A Highflow Rb25 Turbo

[Jim]

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

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... Nothing to be alarmed about

all rb25 turbos are bb thou

[stolen_s15]

Stock they are all BB. But not all hi flows are BB.

[Jim]

ye the only reason i ask is because mine is very loud.... unlike most others ive heard. Definatley can be mistaken for a large BB unit.

[Abo Bob]

I can hear mine for a while afterwards and I don't hvae a pod.

[BezerkR32]

ahhh, no they are not, standard are bush bearing, you can have your hi flow upgraded to BB.

all rb25 turbos are bb thou

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?

BASS OUT

i have a plain bearing hiflow turbo

i have the standard airbox,

only thing i can hear is my walbro fuel pump, when turning off my car.

But when my turbo is windin up, it sounds like a truck turbo.

hasnt blown up yet, sitting on 12 psi, and comes on pretty strong .

[Jim]

how do u hear the fuel pump if the car is off?

[skylinecouple]

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.

[bazr33]

when turning my car off

still on turbo timer

sorry should of said that.

So your saying when you car is turned right off, you hear the turbo winding down?

[Abo Bob]

That's right.

[The Mafia]

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.

[l0WRB]

I have a stage 3 Highflow on my rb25 and i cannot hear mine spool down after i shut off the engine?

[R31Nismoid]

Thats because its most likely NOT ball bearing

[l0WRB]

Thats because its most likely NOT ball bearing

you are correct it isn't ball bearing..
