Random Trivia Department: In his book The Unfair Advantage, Mark Donohue tells of working with Bosch engineers to develop the fuel-injection pump for the first turbocharged Porsche 917. It was a long and drawn-out process, one made more difficult by the fact that both Porsche and Bosch believed the car to be perfect when Donohue first drove it*.
After much prodding and testing, the Germans produced a pump calibration that they claimed was closer to what Donohue wanted. He immediately tested it on the car, shattering the lap record at Weissach in the process. The story has been told before, but it never gets old:
By the end of the year, the five-liter engine was up to 880 horsepower, and the best 5.4-liter engine in 1973 was eventually good for 1190 horsepower. All the time they kept asking, 'Now does it have enough?' And I kept saying, 'I still can't spin the wheels all the way down the straightaway.'"
Incidentally, if you haven't read the book, it's fascinating. Unfair is one of the most entertaining, wide-ranging, and informative motorsport books ever written. If you do nothing else with your life, read A) the chapter on how Penske made the Trans-Am Camaros work and B) the section on the turbocharged 917s. Fascinating stuff, all told by a humble, funny, and thoroughly charming guy. And I was born too damn late.
*Light-switch boost, an on-off throttle, and 800-plus horsepower? Let's go with, er, no.
