Yes, I am talking about impeller. Vanes have some wear on edges. Most worn place is
from shaft to midlength. So, there is not contact with housing. Phil Payne suggested
it is a nut (from shaft, if I remember correctly). I think if it happened it happened
before me because I did not find any object inside and I guess I could've hear some
noise from it.
I am trying to find why the car attain boot too slow and I feel lack of power compare to
my second car. That car has K-24 but the difference in response on stepping on gas is so
big that I don't believe it is
