My wife and I are planning to enter the Lone Star 150 air race this weekend in our 1977 201, and we are trying to determine what to do to prepare for the race, what to do to the plane beforehand, and looking for input as to flying technique.  There are 7 waypoints that must be passed between 500-1000 AGL.  Legs are about 15-30 miles.     So far, the cowl flaps were rerigged, we plan to fly WOT (no ram air on this plane) and around 1000 AGL.  I'd guess 180 MPH indicated is what it would do.
