I was watching some NHRA top alcohol competition and was amazed how those funny cars launched; rev'd high before they were even staged, then roll in to staged. Seems like that would burn up any type of clutch...

trans brake can only be used in automatic transmission, those cars are not using automatic transmissions.

To prevent loss of traction, power transfers from the engine to the rear tires via a complex timer-controlled clutch system. The centrifugal force that squeezes together the five or six discs and four or five steel floaters plates is applied gradually in infinitesimal stages. The procedure is controlled by a hydraulic-fluid-powered throwout bearing and ram until complete one-to-one lockup with the engine and drivetrain is achieved, which occurs about three seconds into the run. The rear end has a 12-inch-diameter ring gear. It must be of the live axle style and use only 3.20:1 gears.

they have what they call a trans brake, it releases the engine from the trans and allows it to rev up so they can launch. the hold the button, hit the rev limiter and lights action camera......it is so cool
