hey ppls.
I'm looking at a new turbo (high flow) soon, and I have seen a fair few turbos lying around in various forms over my time.
When you spin the wheels by hand, some spin heaps some not at all.
Plain bearing turbos dont spin at all after your finger comes off.
Ball Bearing turbos spin a few revolutions, but some keep spinning for a long time after the car stops.
This HAS to be a good sign that the turbo is free to spin as much as it likes.
So, is there a special bearing or something that makes this happen?
Is it a Ceramic bearing that does it?
Do the GCG high flows do it?
All Help Appreciated.
