An otherwise relatively unremarkable hour of racing at Daytona was livened up by a lead change at the front, where Mike Conway and his Action Express Racing Cadillac DPi-V.R stretched out to 23 seconds over Dane Cameron’s Acura Team Penske ARX-05. Conway, on a slightly alternate strategy, used fresh tires to gap Cameron by as much as two seconds per lap at times.

Ford Chip Ganassi’s ownership of GT Le Mans was unchallenged as Dirk Muller and Scott Dixon maintained a one-lap lead over Corvette. Trading of the GT Daytona lead also continued as Madison Snow’s Lamborghini kept eight seconds in hand over Rik Breukers’ Lamborghini.

At 2:55, the No. 78 Jackie Chan DC Racing ORECA 07 driven by Ho-Pin Tung ambled to pit lane without its rear wing. Tung blew the first chicane at the Bus Stop and slid off the circuit into the tires with the rear of the car. Already down multiple laps, the incident did not drastically impact the car’s position in the field.

Mazda’s travails continued as Harry Tincknell, already down 30 laps, stopped for a new left-rear tire after the previous unit blew.

At 2:40, just as a new hour of racing commenced, Pipo Derani pitted with white smoke pouring from the right side of the Nissan DPi’s engine bay.

Asked if the engine had blown, Derani told IMSA Radio “Yeah.”

The Nissan was pushed to the garage where the sister entry, more than 100 laps down, was being tended to by the ESM crew.
