John Lingenfelter

John Earl Lingenfelter (October 6, 1945 in East Freedom, Pennsylvania – December 25, 2003 in Decatur, Indiana) was an NHRA driver, engineer and tuner.

Over his career, Lingenfelter won 13 career national event events in Competition Eliminator and was the first driver in the class to break the six-second quarter-mile barrier.

He was the founder of Lingenfelter Performance Engineering (LPE for short) in Decatur, Indiana. LPE is a shop specializing in the modification of GM vehicles such as the F-Bodies (Camaro, Firebird), B Bodies (Impala SS, Caprice, Roadmaster, Fleetwood), Corvette, CTS-V, GTO, Silverado, Suburban, Tahoe, Escalade, Denali, SSR, Hummer H2, and Sierra.
