John Earl Lingenfelter (October 6, 1945 in East Freedom, Pennsylvania – December 25, 2003 in Decatur, Indiana) was an NHRA driver, engineer and tuner.
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.
Motor Trend tested a Tahoe tuned by Lingenfelter and achieved a 5.1 second 0-60 time as well as a 0.95g lateral acceleration figure.
Lingenfelter built the engine for "Big Red", a 1969 Camaro that has achieved speeds in excess of 200 mph.
He was critically injured during an NHRA Summit Sports Compact drag racing event at Pomona, California on October 27, 2002.
