  Does anybody use system emulation for calculation of the running time of queries on the production system?  


I don't think it's possible. You can copy statistics of production data without copying the data itself. Pretty useful for elimination of queries with really bad plans but that's probably all you can do. Estimates of production run times will require some realistic data volumes.
