Don't have any sound clips to send--just my personal experience/advice on a Pete Jackson "Noisy" drive. I ran one in a small block pro-street Vega and can tell you your g/f would not like it after about 3 days of the constant whine.
Sure ,everyone would turn heads at car shows when fired up (as I pushed in my ear plugs
) I changed it to a good double roller chain drive after about 2 months. Won't ever use one again. And then there are those harmonic issues involved too. Just my 2 cents worth.
