Dedenbear TS1A - THROTTLE STOP; BASEPLATE STYLE; CO2 ACTUATED; STD. HOLLEY 4150 (SINGLE ACTING)

Dedenbears Bear Stop(TM) base plate throttle stops sit underneath the carburetor and operate a second set of butterflies to limit air/fuel flow while allowing the carburetor to remain in wide open position in order to help assist a drag car in an electronics class precisely dial in to a pre-determined ET (such as Super classes) or to aid in running a higher MPH for a given ET. Typically used with a throttle stop timer, there are two actuating methods available offering options for improved simplicity and consistency or maximum tunability. Electric solenoid stops are simple, consistent, reliable and work for a majority of applications. CO2 or air stops offer a tunable flow rate, allowing greater control over the stop butterfly open rate (and in dual-acting models which offer control over close rates as well!), reducing the likelihood of spinning the tires on a high powered car when you transition back off the stop during a run.
