stillen lightweight crank pulley

Is the stock crank internally balanced? If so, there's no harmonic damper. If you see a rubber band like ring as part of the pulley, that's the elastomer for absorbing operation noises such belt rotation sound. A harmonic dampering pulley is easy to spot such as those on domestic engines. Someone should take a picture of the pulley.

The stock pulley is not a harmonic damper, and the engine is internally balanced. There is a rubber piece for NVH reduction. This information is correct.
