K&N Horsepower Challenge

The K&N Horsepower Challenge for competitors in Pro Stock is open to eight drivers; the first seven positions will be determined by points earned at NHRA Full Throttle Drag Racing Series races since the previous bonus event, and the eighth position will be decided by fan vote.

As part of the program, a $3,000 bonus is awarded to the No. 1 qualifier at each NHRA national event. In addition to the $50,000 first prize, $10,000 will be awarded to the runner-up, $3,000 each to the two semifinalists, and $2,500 each to the four first-round finishers.
