Stoffer was on her game Sunday, with an average reaction time of .029 seconds, including a terrific .009 light in a holeshot victory over defending Pro Stock Motorcycle champion Eddie Krawiec in the semifinals.

In the final, though, Stoffer made her slowest pass of the weekend, 7.029 seconds at 190.48 mph, to fall to Ray's 6.920-second run at 192.77 mph.

"We slowed down progressively through the weekend," Stoffer said. "We did notice we were starting to lose a little vacuum on it. We're definitely going to take that motor out, and we'll have a new motor for St. Louis. We weren't exactly sure if it was the battery or the vacuum or what it was, so we went ahead and ran it.

"It actually spun pretty good in the right lane. We had run the right lane in the first round, and we ran pretty good there. But in the fourth round, it had a little more heat in it, and it was a little more slippery. Our 60-foot fell off."
