France's Simon Pagenaud posted the top speed on the fastest day of the week at Indianapolis.

The Team Penske topped the Indianapolis 500 speed chart by going 230.698 mph late in Friday's practice.

Six drivers hit the 230 mark after series officials gave all cars a boost of roughly 50 horsepower for qualifying weekend.

Scott Dixon, of Target Chip Ganassi Racing, came in second at 230.655. Tony Kanaan, Dixon's teammate, was third at 230.457. American Marco Andretti was fourth at 230.312

But after two consecutive days of big crashes, there were no crashes Friday.

Qualifying for the 500 begins Saturday. The nine fastest cars will advance to Sunday's pole shootout and the final three qualifiers from Saturday can be bumped from the May 24 race.
