Message	If you start pushing towards 1000rwhp, I think it is foolish to run an undampened lightweight pulley, considering how much is at risk if you blow your engine. Of the broken cranks that I've seen...they were all running undampened pullies. But then again they were approaching 1000 rwhp...so it is hard to say if the crank broke because of too much power, or it was due to destructive harmonics.
