They do make a different noise. But, I found mine very, very tight from the factory. Loosened it up a bit and everything's rosy now.

The belt also needs alignment between the pulley side rims. I adjust mine on a lift in the garage with the engine in third gear. Just be careful with the pinkies close to a rotating wheel.

BTW, really tight is probably hard on the rear bearings and the drive shaft bearing as well. This is my second belt drive so I learned a little from the first.
