Granted this article is a few years old this might give people an indication. Average Salary
In a 2008 “Ebony” magazine article, leading National Hot Rod Association (NHRA) stock drag racer Tom Hammonds estimated the average salary of a successful professional drag racer at about $150,000 per year. Adjusted for 2011 inflation rates, that comes to about $158,000 annually. In 2007, DragList journalist Steve Klemetti collected a sampling over 350 professional drag racers. The majority of pro racers — those with average performance records — reported annual earnings in the $20,000 to $40,000 range.
Earnings Range
Earnings reported on DragStrip's 2007 list exhibited a staggering range, starting as low as $250 and reaching as high as $1.08 million. Of the 359 drag racers that reported salaries, 16 percent earned over $100,000, 5 percent earned between $50,000 and $100,000, 6 percent earned between $30,000 and $50,000 and 12 percent earned between $20,000 and $30,000.
