Heh, taken it out today again. I am pretty sure the blades are catching. I am running a K14 at 14.5 psi (standard pressure). I had taken the turbo off to replace the manifold gasket so I don't know if that might have caused it. It was running 22psi before though. I don't know if it is because I didn't change the oil for a couple years, but then I had only done about 6k the last couple years anyway.
