Sounding like you know what your talking about and acually knowing is two, totally differant things.

To the one that is saying it will damage your engine and that F2's are not balanced is dead wrong.

Have you acually ever looked at a F2 crank? What do you think those drilled holes in the crank are? They are balanced from the factory. If they werent, they would blow apart on the dealers lot.

The stock pulley isnt damping anything. They arent filled with anything, except a thin layer of adhesive that hold the outer ring and the center piece together. The F2 is internally balanced, meaning that the external attachments are balaced independantly. As long as the flywheel and pulley are balanced within a resonable range, there will be know problem.

A harmonic damper is filled with usally epoxy, you drill through a F2 pulley and let e know how much you find, o yeah, NONE! Its not filled, solid metal except for the thin layer of the adhisive.

Carl, rest assured your engine is fine....
