But don't get the impression that Moby Dick was just an aero kit on a 935, as there were other, less visible changes to the race car.
The turbocharged flat six was bumped up to displace 3.2 liters and fitted with water-cooled heads. When it was time to race, the four-valve engine developed 750 horsepower. Since the Le Mans circuit runs clockwise, the driver's seat was moved to the right to optimize weight distribution. On the Mulsanne Straight, it could hit a blistering 235 mph.
Moby Dick qualified third at Le Mans in 1978, behind two Group 6 prototypes ( Renault Alpine and a Porsche 936). While it was the fastest on the straights, it finished in eighth place after an oil leak became an issue. It ran in two more races that year before Porsche retired it to the museum. Three clones were eventually built, and they raced well into the 1980s.
