Lingenfelter Performance Engineering (LPE) is a company specializing in high performance automobile modifications in Decatur, Indiana, founded by and named for NHRA driver John Lingenfelter. LPE has created high performance versions 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. The shop has also created tuning packages for the Dodge Viper and Plymouth Prowler.
In the press, LPE-tuned vehicles were reported to have as much civility as the stock vehicles upon which they were based in everyday driving. However, these vehicles were brutally fast. Motor Trend tested a Tahoe tuned by Lingenfelter and achieved a 5.1 second 0-60 time as well as a 0.9g lateral acceleration figure. These numbers match the performance figures of the C4 Corvette and GMC Syclones/Typhoons of that era. This Tahoe had its 350in.3 V8 bored and stroked to 396in.3, making 500 hp and still retaining its 4WD drivetrain. Motor Trend also tested a LPE-built Impala SS that had the same performance numbers as the last generation M5 (0-60 4.7 sec) due to its bored and stroked LT-1 (Displacement rose to 383in.3 and horsepower rose to 440)[1]. Another LPE vehicle was featured in the June 1996 issue of Car and Driver: a special C4 Corvette with a 427in.3 engine that attained a top speed of 212 mph.[1] LPE's 2001 corvette 427 with 800 Rear-Wheel horse and a twin turbo accomplished a 1.97 second 0-60. [2]. Currently, the most powerful vehicle they have in their stable is a 2006 twin-turbo Corvette Z06 with 1,109 rear wheel horsepower worth $288,540.
