In the mid-Eighties, Porsche released the 962, a long-wheelbase variant of the 956, to compete in IMSA's GTP class and later in Group C (as the 962C). Even though IMSA's GTP rules stipulated that only one (unfortunately named) KKK turbocharger could be used, the 962 was bloody-your-nose fast.
This past weekend at the Monterey Historics, Mark Hotchkis proved just how fast the 962 was/is by lapping half the field in his class during a ten lap race. That's kinda ridiculous. In fact, the only car that gave Hotchkis any trouble at all was a nine-year newer ALMS Kremer-Porsche Spyder K8 (the same type of car Derek Bell raced at his final Le Mans).

Awesome vid DJ. It shows just how brutal the older IMSA cars were, and Hotchkis is clearly driving the wheels off of it. It looks like he is blowing right by some of the newer build 962’s. If so, that is a real testament to how well Hotchkis' car is running and to his driving. The 1988 (I believe) and later cars, had twin turbos, twin-cam water-cooled heads, and were much faster then the single turbo, single-cam air-cooled head cars like the Wynn’s 962 that Hotchkis is driving. I love the 956/962, here is one I worked on a bit back in my days as a P-car wrench (sorry for the poor picture quality):
I believe that is the boost knob, often labeled with $$$ to remind the driver that it’s really called the “money” knob. 
The boost gauge is in the center of the dash to the left of the oil gauge, and you can see it drop pretty well at 1:18 as he turns the knob counter-clockwise. I'm guessing he decided to back it off a bit since he put such a huge lead on the pack in the 1st lap.
He was also brake boosting for the rolling start.
