1924 Indianapolis 500

Boyer proceeded to drive the car to victory, and both drivers were credited as "co-winners" for the 1924 race.

After Boyer got out of the car and took over the #15, the #9 entry continued in the race, taken over by Ernie Ansterburg, Corum, and later Thane Houser.

"[3] Boyer re-entered the race with Corum's car and soon passed Bennett Hill and Harry Hartz.

Murphy was signaled that Boyer was rapidly closing and upped his pace, but he soon cut a tire and had to pit.

With 12 laps to go, Cooper made a passing attempt in turn 1, but skidded and again cut a tire, prompting another pit stop.
