Sorry, had to add a catchy title like Woody does...

Just received my Eurocharged pulley today and wanted to do a physical comparison between the ones I now have. Figured I'd share the info with you guys while I was at it.

Firstly, I have to say that the Eurocharged pulley looks well made, with sturdy aircraft grade rivets. Also note, it uses an NSK 32BD45DU bearing vs. the NSK 32BD45DUM used in the stock and C3 pulleys.

So, how do they "measure up"?

Note: I used a digital slide caliper and measured them each at the peak of the grooves (where the belt will ride). On the Stock and EC pulley the lip is the same as the groove peaks. However, on the C3 pulley the lip is larger at 65mm.

Stock:
Dia - 74.0mm
Wt - 41.8 oz

Code 3 (2nd Gen):
Dia - 63.7mm
Wt - 32.8 oz

Eurocharged "61"
Dia - 61.9mm
Wt - 22.8 oz

The EC pulley is also substantially lighter due to the use of aluminum.
Not sure if the benefit of lightness will outweigh the sturdiness of steel, but time will tell.
