Piper gave the Porsche 917 its international debut, alongside Frank Gardner, at the Nürburgring 1,000km in 1969, the year in which he mostly campaigned a Lola T70 Mk3B. The Porsche 917, powered by a Type 912 flat-12 engine, was introduced in 1969 and initially proved unwieldy on the race track. However, continuous development improved the handling, and it went on to dominate sports-car racing in 1970 and 1971.
Legendary sports car driver David Piper drove the Porsche 917 since its inception and recalls seeing it for the first time in 1969. In the '70s, Piper built up a Porsche 917 on an original 917 chassis which he managed to acquire from Zuffenhausen’sSportteilelager. After completion, he stamped the new car with a non-917 serial number to avoid future misunderstandings with 5-LT (LT for Long Tail).
