Rocky Mountain Race Week throws a group of street-legal cars making 2,000 to 3,000 horsepower into a five-day, multi-track endurance test through triple-digit Nebraska heat. This 2017 recap follows day one in Kearney, where sleep-deprived racers are still finishing builds the night before testing begins. Watch to see which of these 2,000-plus horsepower street machines actually survive the heat before the real racing even starts.
