Shifnoid Starting Line Controller & Throttle Stop

Product images may differ from actual product appearance.

Starting Line Controller #254-SN-8000
Eliminate ignition box popping and banging on the starting line. The simple release of a button controls the throttle from a preset launch RPM to full throttle, all while the gas pedal is to the floor. Starting line RPM can be set as low as idle. Launch with a transbrake or line lock. The controller works with all ignitions and includes solenoid and hardware. It cannot be used as a throttle stop.

Double Adjustable Throttle Stop #254-SN-8800
Now 40% stronger, this dual control unit has built-in valves to control both the opening and closing speeds of the throttle. It can function as a throttle stop or starting line controller. For the ultimate consistency, opening and closing rates are pneumatically controlled. This unit is ideal for hard-to-pull linkages, such as dual carbs and fuel injection, and it includes a remote-mount 4-way solenoid, quick-connect fittings, and air line.
