The Carter 9058S ThermoQuad TQ 4-barrel carburetor is a legendary piece of automotive history, specifically designed for the powerful 1976 Mopar 440 V-8 engines found in Chrysler and Dodge vehicles. This carburetor is not just a simple air-fuel mixture controller; it's a symphony of precision engineering and performance-enhancing technology.
The Carter 9058S ThermoQuad TQ is a quad-barrel carburetor, meaning it has four separate barrels, each feeding a cylinder in the engine. This design allows for more efficient fuel delivery, resulting in increased power and torque. The ThermoQuad TQ takes this concept a step further by incorporating a unique temperature compensation feature.
The ThermoQuad TQ features a thermostatic air choker that responds to engine temperature changes. In colder conditions, the choker restricts airflow to the carburetor, enriching the fuel-air mixture to help the engine start more easily. As the engine warms up, the choker opens, allowing more air to flow, which in turn leans out the fuel-air mixture for improved performance and fuel efficiency.
The Carter 9058S ThermoQuad TQ also features a vacuum secondary system. This system allows additional fuel to be delivered to the engine under high RPMs or high load conditions, providing an extra boost of power when it's needed most. The vacuum secondary is adjustable, allowing you to fine-tune the carburetor to your specific engine and driving conditions.
The ThermoQuad TQ is constructed of high-quality materials, including a cast aluminum body and brass internals. This ensures durability and longevity, even under the extreme conditions of high-performance driving. The carburetor is also easy to adjust and maintain, with accessible float bowls, adjustable idle mixture screws, and a removable air cleaner.
In summary, the Carter 9058S ThermoQuad TQ 4-barrel carburetor is a testament to Carter's commitment to performance and innovation. It's a versatile and powerful carburetor that can be tuned to meet the specific needs of your 1976 Mopar 440 V-8 engine, providing reliable and exhilarating performance every time you hit the road.
