Indianapolis, IN — In describing a World of Outlaws (WoO) Sprint car race, fast is probably the most used descriptor. After all, these 1,300-pound cars put out nearly 900 horsepower on dirt tracks that range in size from quarter-miles to half-miles. Lap times can range from under the 10-second mark to closer to 19 seconds, depending on how “fast” the surface is. For three-time and defending WoO champion Donny Schatz, the key is knowing just how fast to go.
