Although its last active owner Dieter Inzenhofer will retire later this month, the legendary ANDIAL name is set to stay in the Porsche family as Porsche Motorsports North America, Inc. announced it has purchased the brand for future use.
ANDIAL is an anagram made from the names of the founding members – the late Arnold Wagner AN; Dieter Inzenhofer DI; and former PMNA president and current consultant Alwin Springer AL. From the company's formation in 1975, it evolved into one of America's most successful and respected independent authorities on Porsche performance tuning.
“We have always considered ANDIAL a member of the Porsche family,and now we are pleased to have the name become an official part of Porsche Motorsport. Arnold, Dieter and Alwin played a key role in growing the prominence of Porsche racing in North America, and their reputation was well-known among both racers and Porsche street car owners well beyond North America,” said Jens Walther, president of Porsche Motorsports North America, Inc.
Plans on how the company will use the ANDIAL name have yet to be formulated.
Inzenhofer, who, along with Wagner met Springer at Vasek Polak's Porsche dealership in Manhattan Beach, Calif., in the late 1960s, is pleased that his company will now be part of Porsche Motorsport North America.
“My whole career and professional reputation has been built on ANDIAL's success with Porsche performance and tuning, and I couldn't ask for a better outcome of my decision to retire than have Porsche Motorsport buy our name,” said Inzenhofer.
Some of ANDIAL's major Porsche sports car racing accomplishments include:
• The 24 Hours of Daytona saw ANDIAL-prepared Porsches in the winner's circle from 1983-'87 and again in 1989. In the 1987 race, the first-through fifth-place finishers were in ANDIAL-powered cars.
• Winning the IMSA Supercar Series championship in 1992.
• IMSA-GT Championships in 1983, 1985, 1986 and 1987; North American GT-1 Endurance Cup Championship in 1994 and GTS-2 in 1996.
• Winning the SCCA World Challenge championship in 1994.
• Class wins at Pikes Peak in 1994, 1996, 1997 and 1998.
The impressive list of drivers that campaigned ANDIAL-powered Porsches include Al Holbert, Mario and Michael Andretti, Al Unser Sr. and Jr., A.J. Foyt, Derek Bell, Rolf Stommelen, Johnny Rutherford, Danny Ongais, The Whittington brothers, Bob Wollek, Harald Grohs, Hurley Haywood, Hans-Joachim Stuck, Jim Busby, Pete Halsmer and Jeff Zwart.
Along with ANDIAL's racing ventures, the company developed street-tuned performance applications. In 2004, with their ex-partner Springer officially retired from PMNA, Inzenhofer and Wagner reduced their workload but
did not retire entirely. Instead, they moved from Santa Ana, Calif., to a smaller location in nearby Fountain Valley and gave up the daily Porsche service business, focusing on their specialties, including engine projects, maintaining prior special engines and restoring race or other significant cars, and they continued to supply parts that customers had come to rely on during the preceding three decades.
