CRANK WOBBLE!! Updated, found problem

Is the crank forged?
Is it double keyed?
Is that a stock damper?

Was the blower belt too tight?

Stock forged crank, single key, stock damper. Blower belt did not appear to be to tight. The only big difference I can figure is that I was running a smaller top pulley and had the boost up to 10 to 11 lbs.
