ABSTRACT:
An apparatus for automatically controlling the activation of the throttle on a carburetor on the engine of a drag race car before the start of the race while staging the car. The apparatus eliminates some of the tasks a driver must perform during the process of staging and launching a race vehicle on the starting line(such as physically depressing the throttle pedal) using a starting line throttle actuation system for Pro tree and Full tree modes for controlling the throttle opening. In both Pro and Full tree modes, the staging process is simplified by allowing the driver to stage with the throttle pedal pre-depressed in the wide open down position, with the actual opening of the throttle controlled by the starting line throttle actuation control system. The apparatus has the driver use the same staging procedure for both Pro tree and Full tree races, thus eliminating separate training that has been required for Pro and Full tree races. The apparatus automatically controls the timing and opening rate of the throttle, eliminates driver error in failing to open the throttle at the correct time in response to the race start signal, and reduces or eliminates engine stumble caused by applying the throttle too quickly.
