1. A time operated throttle closing device for use on a drag racing vehicle which comprises:
- means for selectively closing the throttle of an engine of a drag racing vehicle;
means for selectively deactivating said closing means;
means for sensing the initiation of the acceleration of the drag racing vehicle;
an adjustable timer for measuring a preselected period of time from the initiation of acceleration of the drag racing vehicle;
means for activating the closing means after the predetermined period of time has elapsed.

6. A time operated throttle closing device for use on a drag racing vehicle which comprises:
-
a pneumatically operated cylinder and piston; and a piston rod operatively connecting the cylinder piston to the throttle linkage of the drag racing vehicle so as to close the throttle when air is injected into the cylinder; and spring loading means for returning the piston and piston rod to its original position after the injected air is vented from the cylinder; and a valve connected to the cylinder for selectively injecting high pressure air into the cylinder or venting air from the cylinder; and a rechargeable high pressure air tank; and piping means connecting the high pressure air tank to the valve; and means for sensing initiation of movement of the drag racing vehicle; and an adjustable timer for measuring first and second, sequential, preselected periods of time from the initiation of acceleration of the vehicle; and solenoid control means for opening the valve to inject air into the cylinder at the conclusion of the first period of time, and for venting the valve to vent air from the cylinder at the conclusion of the second period of time.
