What is a velocity stack filter?

Spectre’s air filter inlet adapters and velocity stacks are designed to allow you to attach a larger 6 inch diameter flange air filter onto a smaller diameter air intake tube. In addition, Spectre velocity stacks also have a smooth funnel shaped inlet that reduces restriction and turbulence of incoming air.

Do velocity stacks filter air?

Re: Velocity Stacks & filtering? A filter in a stack will seriously upset airflow, and defeats the purpose of a stack. In fact, those grills to stop the rabbits getting sucked into your carbs are already a very bad idea on velocity stacks.

Do velocity stacks make a difference?

In simpler terms, Velocity stacks help for a smoother airflow. This, in turn, supplies more air to the engine and if there is more air, you can burn more fuel which ultimately ends in the engine making more power. The length of a Velocity stack plays a significant role in producing efficient airflow.

What is a velocity stack motorcycle?

Think of a velocity stack as the flute of a trumpet. It attaches to the intake side of the carb or throttle body and maximizes Bernoulli’s principle to increase air speed (velocity) through the venturi. Most motocross bikes, although not all, have incorporated a velocity stack into their air-boot design.

Do velocity stacks work on Turbo?

yes they do work however you will see larger results with larger turbo’s. on one of our cusotmers cars, we tuned his car to 490whp on his 2.0 setup. while on the dyno, we swapped in a same 4″ turbo intake but with a velocity stack and it jumped to 517whp with no real changes.

Is a velocity stack safe?

The velocity stack won’t hurt your engine unless you run it without a filter as you then let in contaminants that can accelerate internal wear. Eventually you shorten the life of your engine.

What is the throttle body?

In a traditional spark ignition gasoline engine, the throttle body is the part of the air intake system that controls the amount of air that flows into an engine’s combustion chamber. It consists of a housing unit that contains a throttle plate (butterfly valve) that rotates on a shaft.

Are velocity stacks bad for your engine?

Re: For people that say velocity stacks are bad for your engine…. The real danger is not that the dirt/dust gets into your oil. The problem is getting it into your combustion chamber where it will wear your rings out prematurely.

What are trumpets on an engine?

A velocity stack’, ‘trumpet, or air horn, 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.

Does velocity stack hurt engine?

Is throttle and accelerator the same?

In a motor vehicle the control used by the driver to regulate power is sometimes called the throttle, accelerator, or gas pedal. For a gasoline engine, the throttle most commonly regulates the amount of air and fuel allowed to enter the engine. The further the pedal is pushed, the wider the throttle valve opens.
