The brainstorm of Weapon R Secret Weapon Intake is the result of many hours of rigorous testing and modification of pre existing designs to arrive at the optimum characteristics to deliver the perfect air mass and airspeed to obtain more power. Surprisingly, we reached an intake system that surpassed all others in its performance. The Secret Weapon is designed using its own patented speed velocity theory that made use of the air speed and air mass in the right manner to increase the horse power. This is done by creating two different air flow paths at two different speeds through the tubing diameters that differ. This then creates a vacuum that sucks in more air and ultimately the engine develops more power.

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.
