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 :P

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?

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 .

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.

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? :D

Also, takes about 30 seconds to nearly a minute to completely spin down with that metalic noise after the engine has been turned off.

      High temp brake fluid?

      By Komdotkom · Posted

      Reasonably hard, although I haven't run it with the new Endless setup yet. The old brakes were F50's on 335mm rotors and the car did a 1:40.6 at Phillip Island which is a reasonable time, I'm seeing high 600s on the temperature paint. A guy I know ran the Endless fluid at WTAC without issues and he was doing 1:33's I think (Evo) with a 355/332 setup. I don't get out to the track as much as I'd like but we put the car on the hoist and spanner check every bolt and re-paint mark everything, bleed the brakes, change the fuel, check the coolant system and re-bleed blah blah blah before every event. Motorsport is expensive, RB's are expensive so a couple of hours before an event is time well spent. It's also a net time saving because if you can keep your RB from self destructing it saves you time in the long term!

      Hello! I'm new here, I have an R33 GTST that is currently being finished up! Last year was pretty rough, blew two stock turbos so I decided to build the car. Has been down since November, but I get it back next weekend!

      Hello, I believe my car was imported to America in the 2000s by Kaizo Industries. Would anyone be able to help me find more info on them? I've only found all the basic stuff like that paul walker bnr34, them being shutdown by feds, just stuff like that. Any help would be much appreciated, thanks!

      HKS Vcam Step Pro Issues

      By believer · Posted

      I am using Motec M150.  I am not working on the car myself actually.  My workshop is giving all these info, they are quite reputable in the industry and are very familiar with Motec and RBs and have done a few big setups with VCam and single turbo on RBs.  In fact, they built and tuned my engine from day one.  But they are stumped with my engine at the moment and cannot work out how come the compression is so low with the VCam. They told me that they have now swapped in some Kelford cams (without the VCam) and can achieve around 130psi compression and the low end torque is better, but now the engine is doughy as.  It boosts and peaks at more than 1000rpm slower, with twin HKS GTIII RS, it doesn't get full boost until over 5000rpm. I have always thought the VCam was a bit disappointing at the low rpm. To a point I had to ride the clutch a fair bit to get up a small hill from stand still.  That was when I had a clutch.  Now changing to a 8HP, I don't have that luxury and this problem has become a major issue. I am beginning to think the VCam never work since the day it was installed.  Maybe it was just sitting at the most advanced point, that is why it went good at top end but very ordinary at the bottom.  Therefore, with the help of the Holinger 6 speed and paddle shift, as long as it was moving, it drove pretty good.
