This model was Porsche’s absolute weapon of a car that performed well in ’76, and was the genesis of one of the most famous of all Porsche’s racing cars, the 935/78 Moby Dick.
Starting with a 3.0-liter flat-six from the road-going Type 930 911 Turbo, it was rebuilt and reinforced with racing strength components, reducing it to 2.85 liters, and tuned to produce 561 BHP and 438 lbs-ft of crank torque with a single turbo. At the end of the 1976 season, a fully 3.0-liter twin-turbo version was produced that could, at maximum boost of 22 PSI, produce over 630 BHP.
The car in this video is a 2.85-liter single turbo that was bought by a Porsche customer racing team, and fitted with a 1977 body to race in Group 5 in ’77 and ’78. This exact chassis came second in class at the 1977 24 Hours of Daytona.
Carrying the original Jolly Club livery that it wore in the 1970s, it is a joy to hear that single turbo spin up and the throaty exhaust bellow out its song.
