Kellymoss with Riley enjoyed a victorious debut in the IMSA Michelin Pilot Challenge Friday at Daytona International Speedway, and it couldn’t have been more dramatic.

Riley Dickinson, who won the Porsche Carrera Cup North America Pro class championship in 2023, displayed remarkable fuel-saving skills that made a daring pit strategy orchestrated by legendary engineer Bill Riley work to perfection.

Dickinson started the last lap in second place in the No. 91 Kellymoss with Riley Porsche 718 GT4 RS Clubsport but swept into the Grand Sport (GS) class and overall lead of the BMW M Endurance Challenge when Kenton Koch pitted the No. 92 Random Vandals Racing BMW M4 GT4 (G82) for a splash of fuel.

Dickinson, who teamed with Michael McCarthy and Brady Golan, had enough fuel on board to hold off a rapidly closing Daniel Morad in the No. 57 Winward Racing Mercedes-AMG GT GT4 and win the season opener. The Kellymoss with Riley Porsche crossed the finish line with a 1.936-second advantage. Matt Plumb and Owen Trinkler finished third in the No. 46 Team TGM Aston Martin Vantage GT4, 6.554s in arrears.

Riley made the call for Dickinson to pit for fuel near the end of a full-course caution with an hour remaining in the four-hour contest. The No. 91 Porsche was in 10th place entering the final 15 minutes, but one by one competitors were forced to stop for fuel.
