It seems like pretty much all sports have rules that limit how much technology can improve performance. I have always though it would be fun to do a mythbusters-style show that tried to see just how much faster/farther/longer people could go with no limits on mechanical aids (as long as there weren't motors). So how far could you hit a golf ball if there were no rules on how the club or the ball were made, how fast could someone swim if there were no rules on what you could wear, etc.
