997 Cup Throttle Blipper, this part is designed for the 997 Cup Car with a sequential gearbox. It is designed to blip the throttle for you on downshifts. Especially helpful for drivers learning to drive a sequential gearbox. With the use of the blipper we see much better wear on the internals of the gearbox and the driveshafts are lasting longer. Porsche decided to supply a different version of a throttle blipper on the 2011 Cup Cars, top teams have been using this blipper for quite some time all over the world.
