I was just wondering if anybody has picked up counts of knock by changing there crank pulley...i.e I just put unorthodox pulley kit on my car.

I have tuned a car with a crank pulley and did not see any knock that would be attributed to the crank pulley

That being said is there is only one crank pulley I would run rather then stock and they do not make them for the evo. Your stock pulley is fine and does a great job.

OFF TOPIC You have a picture of your dyno sheet. I would love to see the spool characteristics on the Hafe manifold with a GT30 turbo.
