I'll measure mine up and post. I originally measured from the outer edge on the face of te pulley. So 2.75 is definitely larger than the surface the belt rides on so 2.44 may actually be the right length. If that's the case 2.5 seems to be the choice to go with. The alternator is a billet unit and I'm told that it can handle quite a bit more rpm than a cs144 without even warming up.
