Spiking in popularity in the 1990’s, the Turbo became, and remains a race car lovers favorite! The following excerpt from Randy Leffingwell’s book Porsche Turbo: The Inside Story of Stuttgart’s Turbocharged Road and Race Cars offers an inside look at the first half of the turbo’s most popular decade! Racing in the 1990s The 3,164cc twin-turbocharged ?at six developed 474 horsepower at 6,900 rpm. Sadly, co-driver Walter Röhrl collided with a spinning prototype six hours into the 24 at Le Mans and the car retired. Porsche Archive 1993 964 TURBO S LM 3.3-LITER Porsche has created special cars for Le Mans since 1951. These vehicles have served as proving grounds for engineering ideas and publicity generators drawing new customers to the company. One such effort arrived in 1993, when the World Sportscar Championship (WSC) had disappeared and a new series was to begin the next year. For the ?rst time in several years, Le Mans organizers welcomed production-derived GT cars to the grid. Into this mix, Porsche inserted the nearly unique 911 Turbo S Le Mans GT. The competition department assembled one car for the race and another as a test and development model. Hans Mezger’s engineers tweaked the 3,164cc twin-turbo Typ M30/69SL to develop 474 horsepower at 7,500 rpm and to create 406 pounds-feet of torque at 5,200 rpm. The car weighed 2,328 pounds. It debuted in March 1993 at Sebring, where it won GT class and ?nished seventh overall. At Le Mans, it quali?ed as the fastest GT car and hopes were high. Then a few minutes after 10:00 p.m. on the car’s seventy-ninth lap, a 2-liter prototype spinning out of control collided with team driver Walter Röhrl. The impact split the oil cooler and ruined the engine before he reached the pits. Before the season ended, Porsche sold the car to privateer Jack Lecomte. At Daytona in February 1994, despite a qualifying session incident that adversely affected handling, the car ?nished second overall. It took ?rst in a four-hour race at Paul Ricard, repeated at Jarama in Spain and again at Suzuka in Japan, ?nishing the season with a win at Zuhaï, China. The GT America pulled out of theDaytona pits for practice. It used theTyp M30/69 ?at six. This Brumos entry retired after 467 laps with a broken fan belt. Porsche Archive The Typ 993 GT2 used Porsche’s 3,600cc twin-turbocharged M64/81 that developed 450 horsepower at 5,700 rpm. Weissach motorsports department assembled forty-three of the cars that weighed 2,425 pounds. Porsche Archive Following development and testing at Weissach in February 1992, Porsche shipped the car to Brumos Porsche in Jacksonville,Florida. Hurley Haywood drove it to the season championship. Porsche Archive 1993 964 3.6-LITER IMSA SUPERCAR Starting in 1991, Porsche drivers contested IMSA’s Bridgestone Supercar Championship in 911 models. By 1993, Brumos Racing in Jacksonville, Florida, ran the factory-supported effort. All entries ran identical Bridgestone street tires. Porsche’s competition department engineers and Brumos’ racing team pulled 450 horsepower from the 3,600cc M64/69SL twin-turbo engine at 6,000 rpm; it developed 395 pounds-feet of torque at 4,800. Vehicle weight was tied to engine displacement, and the supercar raced at 3,155 pounds, carrying 220 pounds of ballast to meet the minimum, but placed exactly where Norbert Singer and his engineering staff had calculated to enhance handling. In 1993, with American Hurley Haywood and German Hans Stuck sharing driving duties, the Brumos team took the season championship and Stuck claimed the driver’s title.

Porsche made history when it brought turbocharging to the racing world in the form of the 917. When strict regulations regarding engine displacement took away the option of bigger engines, manufacturers turned to forced induction. In its wildest trim, the original 12-cylinder turbocharged Porsche racing engine yielded as much as 1,400 horsepower! Porsche’s official philosophy was that racing cars must have a connection to street cars, so it was preordained that Porsche would eventually produce a turbocharged version of its air-cooled flat-six cylinder engine. The resulting 930 Turbo appeared in the spring of 1975 in Europe. Acceleration from 0 to 100 kilometers per hour took a scant 5.5 seconds, and its top speed was 155 miles per hour. The Turbo’s distinctive rear wing let the world know that this was something very special. It was nothing less than the rebirth of the high-performance automobile. At a time when the big-block engines in America’s so-called “muscle cars” were putting out 180 horsepower and the engines in exotic supercars weren’t much more ambitious, the lightweight Porsche was a genuine rocket. Porsche Turbo: The Inside Story of Stuttgart’s Turbocharged Road and Race Cars celebrates Porsche’s five decades of turbocharged supercar performance, both on the track and on the street. It covers all of the major racing cars as well as the turbocharged street cars, including the 930, 935, 924, 944, 968, 911, and Cayenne Panamera. Don’t let this one fly past you!
