I just got back from engine lab. And talked to him about the ctr crank pulley. I told him the story on how they are known to shattering oil pumps because there is no harmonic balacner. He said basically " Thats a balacning problem" So iam thinking if iam balacning the whole bottom end with the crank pulley to the machine it would be fine to use.

I already told him that its going to see at the highest 10K although I don't really see any reason to go that high. But just in case, leaves room for error I guess. Iam doing the street performance balance which I think and he said would be best. What do you guys think about this? If not its easy to switch over to a b16 crank pulley.
