Feb 15, 2017 · Velocity stacks are also called intake trumpets, which gives you a bit better idea what they are. They're little trumpet-shaped air intakes for your engine. The trumpet shape smooths the flow...

A velocity stack, trumpet, or air horn [1] is a typically flared, parallel-sided tubular device fitted individually or in groupings to the entry of an engine's air intake system to smooth high speed airflow, and allow engine intake track tuning to incorporate pressure pulses created by …

May 7, 2023 · Discover the history and science behind velocity stacks, their crucial role in high-performance engines, and how they enhance modern cold air intakes for optimal power and efficiency. Unleash your engine's true potential with this fascinating deep dive.

The goal of stack design is to specify the minimum flow of the exhaust system, exhaust velocity, and stack height that ensures acceptable air quality at all locations of concern. This also reduces the exhaust system’s energy consumption.

Apr 20, 2024 · Velocity stacks, also known as intake trumpets, are trumpet-shaped air intakes for the engine. Their shape makes the airflow to the intake smoother, allowing the most air possible to flow through the given intake volume to generate more power for the engine.

Oct 28, 2009 · Here's EVERYTHING I know about velocity stacks: Short for high RPM/horsepower (think F1 engine). Long for torque (think classic fuel injected drag race engine) Mixed lengths for wide powerband (think CanAm engine) Nice wide rolled-over radius at the inlet works best for all lengths (per David Vizard's tests): _____

Oct 3, 2024 · Velocity stacks enhance the flow of air into the air intake system, leading to more complete fuel combustion. The lengths of these stacks are carefully calculated to align with specific engine harmonics, advancing the engine’s …

A velocity stack is a trumpet-shaped device of differing lengths which is fitted to the air entry of an engine's intake system, carburetor or fuel injection It is designed to: 1. Allow smooth and even entry of air at high velocities into the intake tract with the flow stream adhering to the pipe walls.
