SECRET WEAPON INTAKE
The Secret Weapon Intake Systems is an result of countless hours of testing and tuning of air intake velocity, Airmass and Airspeed for each vehicle application. The Result, an intake system that performs better than any Cold Air Intake, but with a Short Ram. It is possible by Weapon*R's Patent Pending Speed Velocity theory, By creating a higher airspeed in the intake path you increase airmass and airspeed, which greatly increase horsepower.
This is possible by Creating two different paths of airflow, both flowing at different airspeeds, due to the tubing diameter in which the air is traveling. Now when the 2 different paths of air meet,they create a vacuum, which is where the airspeed starts to multiply, forcing more air into the engine at a higher rate, creating more horsepower.
The Secret Weapon Intake Systems are carefully CNC mendrel bent out of 6061 Aluminum, and then Hand Tig Welded in sections to ensure a constant balance in airflow, regulation in airspeed, positive seal and proper fittment. Each one of these intake systems are carefully tuned, by matching the engines displacement, air intake capacity and airspeed to the intake systems tube size,length and secondary pathway tubing diameters to maximize the full potential of the SECRET WEAPON INTAKE SYSTEM.
This Intake is Matched with our Newly designed SW1 Filter, which provides maximum airflow, with the protection of high quality dense Poly Urethane Foam. Many studies have shown Flow rates of up to 80% more Air and Better Dirt Filtration with Foam Filter than the conventional cotton filter. The SW1 main feature is an Computer CAD Designed and Flow benched Tested TURBO Velocity Stack, which greatly increases airflow ,airspeed and airmass into the engine, therefore increasing engine performance. Another one of the SW1 Filters great features are the capability to be dis-assembled to be cleaned and then re-assembled after cleanings or to change the color of the foam filtering element.
We would like to explain how the " SECRET WEAPON " Intake system works.
Here are some pictures of a flow test done with our specially designed flow bench.
Our flow bench is very similar to those used to test flow in machine shops. We measure pressure, in this case vacuum pressure, inside of the pipe. The form of measurement we use is in H2O, or inches of water. This is the same as a majority of industry flow benches. Almost all flow benches use a meter called a Manometer, which has actual water in it, to make its measurements. We opted for a more precise method, using a precision tuned digital vacuum meter, provided to us by The DigiVac Company. The easiest to read this is the higher the number on the display, the better the flow is through the pipe. All test shown were performed using a Craftsman 5hp wet/dry vacuum as a vacuum source.
Picture 1 : Picture of the PATENT PENDING " Secret Weapon Intake Pipe " design. You can see the smaller inner tube used to increase velocity. The airflow through the inner tube has a higher velocity than a standard 3" intake pipe. The higher velocity / volume of airflow from the inner pipe creates a low-pressure vacuum at the throttle body end of the pipe, called a Venturi. This Venturi draws the air from the outer pipe, increasing its velocity, and increasing the overall volume of air entering the engine.
Picture 2 :In this picture, we first test a standard 3” pipe. Here you can see that the display is reading 1.4 in H20. We cap off the other pipe to provide a more accurate reading.
Picture 3 : In this picture we are now testing the Secret Weapon design. We see that the reading has increased to 2.3 in H20. This increase is due to the small inner pipe increasing velocity in the intake tract.
Picture 4 : In this photo, we test a pretty good-sized K&N style gauze filter. You can see that with this filter, the reading has actually DECREASED down to 2.0 inH2O.
Picture 5 : Swapping a Secret Weapon filter for the gauze filter, shows a large increase over the gauge filter and over just the open pipe as well. The improved velocity stack and filter design encourages the air to flow in a direct route through the pipe while maintaining a high velocity and low restriction.
What does this all mean?
The Secret Weapon uses two important laws of physics to increase airflow. The first law is Boyles law. This law basically states that as air velocity increases, its volume increases as well, while the pressure decreases. The second law is the Bernoulli Equation, where a moving fluid (in this case air) has a lower pressure than air that is standing still, or is moving slowly. This same law is used in NASCAR for both downforce and "drafting." When we increase the air velocity in the intake, we create a low pressure area that draws a higher volume of air than a standard intake would. In layman's terms, we are creating a vacuum effect using natural laws of physics.
Do the Weapon*R Air Filters, filter dirt better than K&N / AEM / Injen Air Filters?
The Secret Weapon Air Filter is made of Polyeurethane Foam, which is rated at 300 Pores per square inch. Whereas the K&N / AEM / INJEN air filters are rated at 30-60 pores per square inch. This means that there is more dirt particles passing through the air filter to the engine when using their filters.
Why is the Secret Weapon Air Filter so much better?
The reason why the Secret Weapon Air Filter flows much better than any other filter on the market today is because of the specially designed Velocity Stack inside the air filter, it helps gather more air into the air filter and velocitize the air into the intake tube.
