Velocity Stacks For Engines

Velocity Stacks For Engines

Velocity stacks, also known as air horns or trumpets, are a type of intake system that is commonly used in high-performance engines. These stacks are designed to improve the flow of air into the engine by reducing turbulence and increasing the velocity of the air entering the intake manifold. This improved airflow can lead to increased horsepower and torque, as well as improved throttle response and engine sound. The basic design of a velocity stack consists of a cylindrical tube with a flared opening at one end. The flared end is positioned facing the incoming air, while the other end is attached to the intake manifold. The shape of the flared end is carefully designed to create a smooth transition from the outside air to the inside of the tube, reducing turbulence and increasing the velocity of the air as it enters the engine. One of the key benefits of velocity stacks is their ability to increase the resonance of the intake system. This resonance can create a pressure wave that helps to push more air into the engine during the intake stroke, resulting in improved engine performance. However, it is important to note that the design of the velocity stack must be carefully matched to the engine's specific characteristics in order to achieve optimal performance gains. In addition to their performance benefits, velocity stacks are also popular among car enthusiasts for their aesthetic appeal. They can be made from a variety of materials, including aluminum, carbon fiber, and stainless steel, and can be finished in a range of colors and textures to match the style of the vehicle.
