Does anyone know the true reason why TPC's supercharger has problems?

There are plenty of 996 onwers who are running centrifugal superchargers, and have had no problems thus far. Does the 996 use different engine internals then the 986?

The 996 engine block is made out of a different alloy than the 986 engine block. External component similarity aside, these are different engines.
