Used 11mm 66 GT center flange tooth blower pulley. This pulley is 3.875" wide has a 2.00" register with six .375" bolt holes on a 2.782" bolt circle made from billet aluminum and hard anodized for wear resistance. Pulley has been bolted on but looks like it never has had a belt run on it.
If you are going to rotate the earth with a screw supercharger slap this pulley on and let the possibility of 175% overdriven cross you mind if you feel your tune up is ready for some serious boost!!!
