The Quad Flow Torque Wing has horizontal and vertical air flow stabilizers which increase air flow, air speed and fuel atomization, thereby increasing performance. The Quad Flow Torque Wing may be used separately or in conjunction with any of our other products to further enhance overall performance. Install for maximum performance, then HANG ON!

The Torque Wing produces substantial gains across the RPM range. Throttle response is extremely quick. The Torque Wing is installed on the engine side of your carburetor slide. This divides the carburetor bore into four quadrants, utilizing a horizontal and vertical air stabilizer. These stabilizers virtually eliminate air turbulence thus increasing air velocity to the engine. This improves fuel atomization and power. All engines whether two cycle or four cycle have naturally occurring reversionary pulse waves in the intake tract that are very turbulent. The Torque Wing eliminates this turbulence for another rapid return trip to the engine. The horizontal stabilizer also performs another function. Any throttle position half throttle or below normally suffers a big drop in air velocity due to the air flow that goes under the carburetor slide being allowed to enter the full size of the carburetor bore producing a rolling turbulence and a corresponding drop in air velocity. The horizontal stabilizer prevents this drop in air velocity producing much quicker throttle response and a substantial increase in torque. The Torque Wing continues to kill off multi-directional turbulence all the way through full throttle. A small space is left between the torque wing and the carburetor to equalize and improve the air flow to all four quadrants.

The Torque Wing has been designed to protrude out past the end of the carburetor and into the intake manifold. This holds the air column together longer preventing the break-up which creates turbulence. In most reed valve engines, the air column is held together all the way to the reed valve. Regardless of which intake system you have, reed valve, piston port or rotary valve, the Torque Wing will produce impressive results in seamless power across the rpm range making your machine faster and easier to ride. The Torque Wing utilizes four locating tabs giving you a perfect fit in every carburetor. Two additional tabs are used to prevent the Torque Wing from twisting and also lock it into the rubber intake boot for added security. Constructed from stainless steel, it won’t rust, corrode or be affected by any fuel or additives. This product has been in development for a long time and many patent claims have been filed. Best of all, the Torque Wing is easy to install and requires no tuning. Install it, forget it and enjoy the power. Torque Wings are available for most popular small engine carburetors.
