Ed Pink built engines and handed them to Prudhomme. Waddell Wilson built engines and called the race from the pit box. John Lingenfelter built engines and drove them himself. At 254.76 miles per hour. In a street legal car. On a closed course in East Liberty, Ohio. With a valid license plate and working headlights. The Callaway Sledgehammer record, set in October 1988, stood for twenty five years as the fastest speed ever achieved by a street legal automobile. The engine that powered it was Lingenfelter's. The driver behind the wheel was Lingenfelter. The same man who built the horsepower trusted it enough to sit behind it at 254 mph and keep his foot on the throttle. That is a level of confidence in your own work that no dyno sheet can quantify.
Lingenfelter was born October 6, 1945, in East Freedom, Pennsylvania, and grew up in Indiana. He earned an associate's degree in drafting and design from Penn State in 1965 and went to work at International Harvester, the same company that Bill Wallace fought to build the DT466 at. Lingenfelter worked at IH during the day. At night and on weekends, he built engines and raced. By the early 1970s, the racing had become too successful to remain a hobby. In 1973, he quit IH and went full time. Over his drag racing career, Lingenfelter won thirteen NHRA national events in Competition Eliminator, the class that rewards the most precise combination of engine building, chassis tuning, and driver consistency. He was the first driver in Competition Eliminator to break the six second quarter mile barrier. Not the first engine builder. The first driver. Lingenfelter's hands built the engine that his foot sent into the six second zone.
The twin turbo Corvettes are what made the Lingenfelter name famous beyond the drag strip. In the 1990s and early 2000s, Lingenfelter Performance Engineering in Decatur, Indiana, developed twin turbo systems for C4 and C5 Corvettes that turned factory sports cars into machines that embarrassed exotics costing five times as much. The 427 cubic inch twin turbo C5 Corvette, tested by Motor Trend in June 2002, ran 0 to 60 mph in 1.97 seconds. One point nine seven seconds. The magazine called it the fastest accelerating street legal car they had ever tested. The same car ran 8.95 at 153.6 mph in the quarter mile. A street legal Corvette with license plates, headlights, and a working stereo running eight second quarter miles. The twin turbo packages made between 700 and 1,100 rear wheel horsepower depending on configuration, and the vehicles they were installed in retained the drivability of the stock cars they were based on. Motor Trend noted that Lingenfelter tuned vehicles had as much civility as the stock versions in everyday driving but were brutally fast when the throttle opened. That dual character, the ability to make four digit horsepower without sacrificing the ability to drive to the grocery store, was Lingenfelter's signature.
The Sledgehammer run deserves its own paragraph because it connected Lingenfelter to Reeves Callaway, another name on the short list of American performance legends. In 1988, Callaway asked Lingenfelter to build the engine for a modified C4 Corvette designed to set the street legal top speed record. Lingenfelter built a twin turbocharged 350 small block making 898 HP. Then he drove the car himself on the 7.5 mile oval at the Transportation Research Center in East Liberty, Ohio. 254.76 mph. Street legal. License plate. Headlights. Turn signals. A car that could theoretically be driven to the test and then driven home afterward. The record stood from 1988 to 2013, when the Hennessey Venom GT surpassed it. Twenty five years. No other street legal car on Earth went faster for a quarter century. And the driver who held the record was the same man who built the engine.
Lingenfelter also ventured into NHRA Pro Stock Truck racing in 1997, finishing second in the points standings in 1998 with a Cavalier running 7.08 at 175 mph in the quarter. At Bonneville, a Lingenfelter powered Trans Am driven by Gary Eaker reached 298 mph chasing the 300 mph barrier for full body sedans. The Lingenfelter name appeared in every form of American motorsport that involved going fast in a straight line: drag racing, top speed, land speed, and the street legal performance market that connected all three.
On October 25, 2003, during the semifinals of a Pro Stock Truck race at the NHRA Finals in Pomona, Lingenfelter lost control of his Cavalier and crashed into the concrete retaining wall at approximately 190 mph. He was on a world record setting pace when the car broke loose. He sustained serious injuries including fractured vertebrae and a head injury. John Lingenfelter died on December 25, 2003, Christmas Day, at age fifty eight, from complications of subsequent surgeries. The man who had driven 254 mph in a street legal Corvette, who had broken the six second barrier in Competition Eliminator, who had built engines making over 1,100 horsepower that retained factory drivability, died doing what he had done his entire adult life: racing an engine he built in a car he drove at a speed nobody else would have attempted.
Lingenfelter Performance Engineering continued under his cousin Ken Lingenfelter, who purchased the assets in 2008 and expanded the operation. In 2008, John was posthumously inducted into the Corvette Hall of Fame. The company continues to produce performance packages for Corvettes, Camaros, and trucks, maintaining the philosophy John established: build the most power possible while retaining the civility of the stock vehicle. The fastest street legal car in the world for twenty five years was built by a man from East Freedom, Pennsylvania, who learned engineering at Penn State, learned engines at International Harvester, and learned speed by driving his own creations at velocities that most people can't comprehend. John Lingenfelter didn't just build fast engines. He sat behind them and proved they worked. At 254 mph. That is the ultimate quality control.
