Drag racers never are satisfied until they have made the perfect run. Winning demands such an attitude, but achieving the goal is incredibly difficult. Nowhere is the quest for perfection more intense than in the grueling NHRA eliminators of Pro Stock and Pro Stock Truck. Fields usually are separated by mere hundredths and rounds regularly are won or lost by less than that. Making or missing the show and winning or losing require a perfectly prepared vehicle.
Nothing can be compromised, especially what's inside the bellhousing.
Clutch set-up must be precise so the vehicle and driver leave the starting line first and cross the finish line as the winner. Ironically, clutch tuning lacks precision, which is so important to every other component on a Pro Stock car or truck. Just as the clutch is covered by a bellhousing, setting up the all-important device is shrouded in mystery. Even the most astute clutch-tuning wizard cannot predict exactly how a clutch will perform. Thanks to the ingenuity of Kyle Carrothers, though, clutch set-up is moving from magic to science.
