 Sure Nick - sometimes the Fw 190A could out run a P-51D or B on the deck and sometimes it couldn't.
 
Part of the variables in the discussion include not only the engine performance at that time for either ship, whether or not friction drag was reduced by polishing, what the respective weight conditions were, etc.
 
But I believe if you follow the logic presented by Holtzauge and Harri, you can believe an Fw 190A will not only out run a 51 on the deck but also do it with 5-10,000 pounds of extra weight as the reduction in speed is trifling.
