The Pennington F.A.S.T. racing crew has had similar experinces to what was described above with that type of reproduction pulleys. The centers cracked and broke out of them much faster than the original GM pulleys did. Of course, they are making way north of 400 horsepower, but even so, maybe changing them out should just be considered periodic maintence.
