Bellmouth Velocity Stack Aluminum 3In Inlet O.D

The Bellmouth Velocity Stack Aluminum 3 Inch Inlet O.D. from VIBRANT PERFORMANCE is a precision intake velocity stack designed to enhance airflow dynamics in high-performance engine builds. This component is essential for builders and enthusiasts who recognize the importance of efficient air movement for improved volumetric efficiency and throttle response. Whether tuning a carbureted classic or upgrading a forced-induction setup, this velocity stack is engineered to optimize air intake.

Constructed from aircraft-grade aluminum, the velocity stack features a precision-molded bellmouth inlet geometry that facilitates a smooth transition from atmospheric pressure into the fuel or air-metering system. The 3-inch outer diameter inlet is designed to match common carb flange and manifold bore standards, while the bellmouth profile minimizes turbulence and pressure losses, enhancing peak power delivery. Weighing just 0.3 lbs, the lightweight design is crucial for responsive throttle modulation and accurate fuel metering.

This velocity stack is ideal for various applications, including carbureted and fuel-injected systems, as well as forced induction setups. Its design ensures consistent velocity characteristics across the RPM range, making it a reliable choice for dyno tuning. Builders looking to maximize performance will find that this component significantly improves air intake efficiency.
