AVONDALE, Ariz. — Records at Phoenix International Raceway have been falling faster than the temperatures around the desert track this week.
In the NASCAR Sprint Cup first practice, Kurt Busch surpassed the old record of 136.389 m.p.h. set by Carl Edwards in November last season in the No. 99 Roush Fenway Racing Ford, with a lap of 136.539 m.p.h. in the No. 22 Penske Racing Dodge.
Busch’s record lasted only 24 hours when Edwards won the pole for Sunday’s Subway Fresh Fit 500 with a lap of 137.279 m.p.h.
Busch will start second with a lap of 137.112 m.p.h. and Kasey Kahne was third fastest at 137.996 m.p.h. in he No. 4 Red Bull Racing Toyota.
The air was unusually cold and there was a threat of rain in the Phoenix area, and that, said drivers made for ideal conditions on PIR’s one-mile oval.
Also on Saturday, Busch blew away Jimmy Spencer’s Nationwide record of 131.339 m.p.h. with a lap of 134.298 m.p.h.
The Camping World Truck series track record also fell, with Bowyer, at 133.949 m.p.h. breaking the record of 133.605 m.p.h. that Auton Dillon set in November.
