Cowin is considered a pioneer in Australian drag racing. Cowin was a trucker with a need for speed who began his racing career in 1973 when he and his wife invested everything they had and purchased the famed Psycho nitro-fueled drag car. This led to Cowin moving into nitro Funny Car and Top Fuel racing in Australia and the U.S. While primarily a Top Fuel driver in Australia, he campaigned Funny Cars while in the U.S. and finished as runner-up at the 1987 NHRA Winternationals. In 1993, driving a Top Fuel dragster, Cowin was the first in Australia to run under five seconds with a pass of 4.895. In 1995 he won the Australian Top Fuel championship. In 2013, he created the Outlaw Nitro Funny Car Series, which became a huge success, bringing racers from across Australia and New Zealand together. He was inducted into the Australian National Drag Racing Association Hall of Fame in 2013 and into the Australian Motorsports Hall of Fame in 2018. In 2020 he was named the No. 4 driver on the ANDRA Top 10 drivers list. Graeme has a reputation for being a person of integrity and creativity in the sport. Due to his knowledge of the sport, he opened his own business, Rocket Industries, a leader in the performance parts and equipment provider for drag racers in Australia.
