Carburetor Air Bells & Intake Velocity Stacks

What Does a Carburetor Velocity Stack Do?

A carburetor velocity stack is a performance accessory designed to enhance the airflow dynamics in a vehicle's intake system. Its primary functions include:

• Improved Airflow: Velocity stacks are engineered to streamline and accelerate the incoming air as it enters the carburetor or throttle body. This results in a more direct and efficient flow of air into the engine, which can lead to increased power and throttle response.
• Enhanced Air Distribution: By promoting smoother airflow, velocity stacks help distribute air evenly to each cylinder in the engine. This balanced air distribution can lead to improved combustion and better overall engine performance.
• Reduced Turbulence: Velocity stacks are designed to minimize air turbulence and disruption as air enters the intake. Reduced turbulence can result in less resistance to airflow, allowing the engine to breathe more freely.
• Increased Engine Efficiency: When a carburetor velocity stack is properly matched to the engine's specifications, it can contribute to better fuel atomization and combustion efficiency, potentially leading to increased horsepower and torque.

Do Velocity Stacks Improve Performance?

Yes, velocity stacks can significantly improve the performance of a vehicle's engine, especially in high-performance and racing applications. When properly designed and tuned to match the engine's characteristics, velocity stacks can deliver several performance benefits, including:

• Increased Horsepower: The improved airflow dynamics provided by velocity stacks can result in increased horsepower output, making the engine more powerful.
• Better Throttle Response: The streamlined airflow allows for quicker throttle response, reducing lag when accelerating.
• Enhanced Torque: Velocity stacks can improve low-end torque, providing better performance at lower RPMs.
• Improved Engine Sound: Some enthusiasts appreciate the unique engine sound produced by velocity stacks, which can add to the overall driving experience.

How Much Does a Carburetor Velocity Stack Cost?

The cost of a carburetor velocity stack can vary depending on factors such as brand, material, size, and design. On average, you can expect to pay between $20 and $200 or more for a velocity stack. High-quality stacks designed for specific applications tend to be at the higher end of this price range.

It's essential to choose a velocity stack that matches your engine's requirements and tuning goals. Investing in a well-designed velocity stack can be a worthwhile upgrade for enthusiasts looking to maximize their engine's performance.
