Answer
Richard-

  Well...it depends on what you're doing and how you want to drive.  Normally driving on the street I'd say do it by the seat of your pants...normally around 2000-3000rpm for stop and go traffic.  For more "spirited" driving I wouldn't take it past 5000rpm...5500rpm at the most.  I'm willing to bet that your engine stops making power around 45000-5000rpms so revving it past that doesn't make sense and will damage your engine.  Hope this helps.
