Should be pegging it with a 10%. Before you go and buy a new belt, use some sand paper to roughen up the pulley. Also, its kind of hot out so it may be low because of that. Try it at night.

Belt, Supercharger, Gates Auto Zone K080392

P/N--- Metric P/N--- Eff. Lngth--- Outside Length
4080374--- 8PK0950 8--- 37.438--- 38.188
4080384--- 8PK0975 8--- 38.5--- 39.25
4080390--- 8PK0990 8--- 39 --- 39.75
4080392--- 8PK0995 8--- 39.25 --- 40 *** Stock belt for stock pulley
4080400--- 8PK1015 8--- 40 --- 40.75
4080407--- 8PK1035 8--- 40.75 --- 41.5
4080415--- 8PK1055 8--- 41.5 --- 42.25

Most people use the stock belt above even with smaller pulleys. You can find those others by the same std. number.
P/N breaks down to 4080374 = 4-?, 08=# of ribs, 0374 = 3.74" effective length.
Metric # is the same, just in centimeters I think.
