I just noticed something about my turbo, when the car is idling is the little turbine thing suppose to be at a dead stop?
the little fins in the intake side.

most turbos dont spin when the engine is at idle.. unless the turbine/compressor wheels are very small. This is normal.

 

Thanks man.

 

hmmm mines spins when car is idling. drag gen 3 on a 95 gsr. got the kit used. mayb its not t3/t4 and i got ripped?

 

Mine spins at idle too, and I have T3/T04E for sure. Maybe that's a good sign: nice spinning action, well oiled, light compressor wheel.

 

i got TD04 and its spins too...

 

Let me make a modification. Turbo systems that have free flowing exhausts and a hardly any backpressure, yes the turbo can spin. A turbo that doesn't spin at idle is not a sure sign of a problem, because there will be times that it's not spinning. Just make sure your turbo doesn't leak oil.. that's the main concern. Keep it cool with a turbo timer and make sure your oil feed doesn't have too much pressure.

 

Never heard where it does not spin @ Idle, TO4 spins @ idle

 

Mine isnt Ball Bearing

 

Mines spins on idle.

 

I've seen mine both spin, and NOT spin at idle, and I've got a TD04 with stock exahust.

 

Is the setup affected if it's not spinning during idle? I wouldn't think so, but anyone have any proof if it helps or does nothing?

 

Performance isnt affected at all if it isnt spinning at idle. A highly loose and free spinning turbo will spin during idle. All that means is that the turbo spins quickly when needed to, and its free spinning. No biggie.

 

sometimes mine spins, but most of the times it doesn't spin.

 

so would it matter if it spins or it doesn't at Idle ?
