INDIANAPOLIS -- The pressure of making the Indianapolis 500 amped up considerably on "Fast Friday" as teams desperately searched for the speed needed to make the biggest race of the year.
The two-day qualifying process for the 33 spots in the field begins Saturday and the final day of preparation permitted a boost in horsepower and teams trimmed their cars to the razors' edge for every tenth on the clock.
Conor Daly posted the biggest number of the week -- 231.704 mph in the draft -- to end Friday atop the leaderboard. It's a misleading number since qualifying is done in single-car runs without the tow that adds the extra speed.
