Quin Epperly

Quincy David Epperly (March 3, 1913 – January 7, 2001) was an American race car builder. He developed an innovative 'lay-down' style of roadster with a low center of gravity.

Biography
Epperly was born in Floyd, Virginia, to John Wesley and Iowa Texas Epperly. After completing a correspondence course in "Theory of Aircraft Construction", Epperly moved to Southern California in 1940 to work for Lockheed and Pacific Airmotive. During the Second World War, he joined the Coast Guard Reserve to spend evenings after work on watch at the Wilmington Coast Guard Patrol Base.

Indy car racing
In the late 1940s, Epperly went to work for Frank Kurtis building racing car bodies; this led to a lifelong career in the racing business.

During the mid-1950s Epperly opened his own shop in Lawndale, California, where he came up with a radical approach in racing car design, by placing a four-cylinder Offenhauser engine on its side, rather than in the upright position, as was the usual custom for the Indianapolis roadsters of that era. Called the "laydown Offy," it allowed for better high-speed aerodynamics and oval-track weight distribution.

Epperly's cars competed in five FIA World Championship races - the, , , and  Indianapolis 500; he performed bodywork on the race winner in 1957 and 1958.

Drag racing
Epperly also built the body for the first Spirit of America land speed racer, out of his shop in Gardena, California.

Epperly worked with Nye Frank and Craig Breedlove on the dragster Spirit II in 1964, and with Frank on the Flying Wedge streamliner dragster built for Don Prudhomme in 1971.

Later work
A notable restoration by Epperly was the engine for the Cooper Type 54-Climax, which, in the hands of Jack Brabham, began the "rear engine revolution" at Indianapolis. The restoration earned the car the coveted Monterey Cup at the 1991 Monterey Historic races, when, driven again by Brabham, it performed perfectly. It later traveled to the Festival of Speed at Goodwood in 1993, to Australia in 1995 for the CART Surfer's Paradise race, to Michigan International Raceway in 1996 for the U.S. 500 (where demonstration laps at around 140 mph were made), and to the California Speedway in 1997 for the Marlboro 500.

His last major project was to complete the body restoration of his own Demler Special #99 in 1998. The Demler had finished second in the 1958 Indianapolis 500.
