Harnessing Hell: Top Fuel Clutch Development 1950-1970

This is the story of how early drag racers developed the clutch technology that has ultimately lead to the engineering wonders in today's 11,000hp top fuel dragsters and nitro funny cars. It is the story of experimentation, of failure, of accidents, and of success. The development of the multi-disc, centrifugally controlled clutch was incremental in all areas. From the materials, the design, and finally the manufacture of these pieces, everyone had their own ideas on how to approach the issue. It was one major revelation by racers. The idea that a slipping clutch as far more efficient than slipping tires that allowed performances to sky rocket while the danger level of the sport did the exact same thing. If you love the history of early drag racing, especially the mechanical side of it, you'll enjoy this deep dive into the clutches that almost stopped the sport and then those that saved it.
