    Small Power Pulley mod for M54 cars

    I have been installing several power pulley kits from UUC on M54 and S52 cars lately and as a result, have quite the pile of water pump and power steering pump pulleys in my garage. The S52 and M54 share the same diameter power steering pump pulley (different offset) but the water pump pulley on the S52 is slightly larger than the M54 pulley. By my calculation the fan and water pump will be under-driven by 8.2% with this mod and has been tested by the M division.

    The 11511730554 pulley from the S52 cars is 132mm in diameter
    The 11511436590 pulley from the M54 cars is 122mm in diameter

    You can install the S52 water pump pulley on the M54 car with the 6PK1562 belt (longer than stock belt of 6PK1538).
