I'm looking for the crank pulley diameter for an S2 (6 rib pulley) and don't have a set of calipers and don't trust the string method with belts on. Can any S2 owners please measure their crank pulley diameter for me.

Thanks in Advance!

 

if you want, i can head to silverstar after work (if they're open) and see if they have one and measure it.

that is, assuming you dont get your measurements before that.

 

Thanks for the offer Juan, but if I don't hear a number by the time I get off work, then I'll stop at Kregan's on the way home and get a cheapy dial caliper.

As a side note, I think I need to order a new SC pulley with larger dia so I'm not running so much boost. my calcs based off the string method of measuring say I'll be running almost 8lbs, and that sounds like trouble to me, but I need a good measurement to be sure.
