Earnhardt Jr., on today's engine failure

Dale Earnhardt Jr comments on engine failure during practice for the Budweiser Duel at Daytona Qualifying Races: WHAT HAPPENED?“We broke a motor, it’s as simple as that. They’ll figure out what happen. I’m sure there is some logical explanation as to what happened, but, we’ll just put a new one in and start at the back of the Qualifier tomorrow, and race up through there.”WILL YOU GO TO BED A LITTLE WORRIED TONIGHT? “No, it’s just part of racing.”IS THIS ANY SORT OF A SETBACK? “Not really. Everything is good. We were just making some single car runs by ourselves. Everything seemed like it was working. Just trying to find a little more speed, and we found a few things that seemed to help the car. We’ll try to get out in this next practice, and see what else we can learn, but everything should be fine.”DID YOU HAVE ANY WARNING THAT IT WAS GOING?“No.”
