Clutch slip? We ain't got no Clutch slip........

We don't need no clutch slip. I don't have to show you any stinking clutch slip!

Provoking the snake: SRT® Viper launch control explained.

Launch control in the SRT Viper works on the principle that the rear tires reach their optimal adhesion at approximately 25-percent longitudinal slip. The tires need to turn about 25-percent faster than the car is moving to meet this goal. While launching the Viper, for every 100 feet the car moves, the rear tires turn 125 feet. A small amount of the tire is sheared with every revolution.

Launch control works by balancing the engine’s output with the rear tire’s ability to put that power to the ground and accelerate the car as quickly as possible. The most challenging part of a launch is starting from a standstill. In order to keep the engine in its powerband, drivers typically have to slip the clutch significantly at the beginning of a launch. While fast, this is very challenging to do and is extremely hard on the clutch. The beauty of launch control is that instead of slipping the clutch, it slips the tires in order to keep the engine in the best part of its powerband during acceleration runs. ... ained.html
