Harry Hyde (January 17, 1925 – May 13, 1996) was a leading crew chief in NASCAR stock car racing in the 1960s through the 1980s, winning 56 races and 88 pole positions. He was the 1970 championship crew chief for Bobby Isaac. He inspired the Harry Hogge character in the movie Days of Thunder.
Born in Brownsville, Kentucky on January 17, 1925, he learned to be a mechanic in the Army during WWII. Upon returning home he worked as an auto mechanic and drove race cars for a couple years, then continued racing as a car builder for local competitions in Kentucky, Indiana, and Ohio.
In 1965 he was hired by Nord Krauskopf to be the crew chief of the K&K Insurance team. By 1969 the team began to see considerable success with driver Bobby Isaac, winning 17 races. In 1970 the team won the NASCAR championship and Hyde was named Mechanic of the Year.
The K&K team was one of the leaders through most of the 1970s, but in 1977 Krauskopf sold the team to J. D. Stacy. The team continued to win some races, but in 1978 the relationship between Stacy and Hyde deteriorated and Hyde left the team in mid-June. Late in 1978 Hyde would sue Stacy, and eventually would win.
In 1979 Amelio Scott hired Harry Hyde to be the crew chief for his family team in 1979 with his son Tighe Scott as the driver. Their first race together was the 1979 Daytona 500. Scott finished sixth in the race. At the following race at Rockingham Speedway, Scott recorded his best NASCAR result when he finished fourth. They competed in 15 more events that season and ten more in 1980 before parting ways.
In 1980 Hyde opened his own racing engine shop and supplied engines to various teams. In 1984, he was hired by Rick Hendrick to be crew chief for a team he was partner in, All Star Racing. The partnership did not work out, and Hendrick bought the team out forming Hendrick Motorsports. The team won three races in 1984 with Geoff Bodine driving.
