In a product category that is saturated with cheap knockoff designs, the Power X Wing stands out as the most innovative velocity intake carburetor divider that money can buy. The Power X Wing's unique design maximizes airflow to increase horsepower, torque and responsiveness, without restrictions to your existing carburetor. Precision fit engineering ensures easy installation in each make and model available. The Boyesen PowerWing is designed to increase air velocity inside your carburetor. It does this by streamlining incoming air and works to better prepare the Turbulent air for entry into the carburetor making the flow or air particles more laminar and dense. Simply stated, increasing air speed and density are the two most important aspects of gaining performance in your intake system. That is precisely what the Power X Wing delivers.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan class=\"wrap\"\u003eTHE UNIVERSAL PROBLEM\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eAir becomes very turbulent when it passes through your machine's air boot. Because modern air boots are designed to work AROUND your machine's rear shock, they often sacrifice air speed and air density when delivering it to the carburetor. Instead, most, if not all modern air boots deliver incoming air to your machine's carburetor in a turbulent state. As a result, the turbulent air does not mix in the optimal ratio with fuel while passing through the venturi of the carburetor. In this regard, air boots have always limited the performance of your machine's engine potential, especially in the areas of low-end responsiveness and torque output.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan class=\"wrap\"\u003eTHE EASY SOLUTION\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eThe solution to this turbulent air problem is found in the design of the Power X Wing's air divider wings. The wings are designed to protrude back into the air boot space, speeding up and straightening the air through its four channels and walls, effectively eliminating the turbulence caused from the air being previously directed through the air boot. As the incoming air becomes less turbulent, the molecules are calmed down and take up less volume. Therefore the air molecules are forced closer together, producing a denser air charge. This charge also increases in velocity, because stable and less turbulent air has less friction when it moves at high speed. Furthermore, the air, which is now more laminar (smooth) in flow, is better able to pass the venture and mix with fuel in the proper ration needed for maximum engine efficiency.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan class=\"wrap\"\u003eTHE POWER X WING ADVANTAGE\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eWith improved air flow to your machine's carburetor, you will experience a dramatically improved and immediate increase in throttle response, as well as a substantial increase in the low to mid-range torque.
