Race car technology
For many years race car builders and drivers have been controlling undercarriage turbulence to their advantage.
 By controlling the distance to the pavement, plus the width of the nose piece, vehicle drag and handling can be controlled. This allows the car to be more stable, increase power, and reduces fuel consumption, thereby increasing the distance between fuel stops.

Reduced turbulence
When a large vehicle travels over a wet road, there is substantial amount of "splash and spray" which is forced from underneath the vehicle.
This turbulence not only interferes with the driver's visibility and control of the vehicle, but can also be a concern to other vehicles during passing. Turbo Shield greatly reduces this turbulence, increasing safety as well as those around you. |

Improved fuel mileage
Attached to a vehicle just in front of the axle, the extremely durable polypropylene
Turbo Shield greatly reduces undercarriage turbulence.
With significantly less drag, operators of semi-tractors, dump trucks, step vans,
motor homes and pickup trucks can see improved mileage.

Improved aerodynamics
Air that would normally travel underneath the vehicle and create significant turbulence is diverted around and down the sides, making large vehicles much more controllable and safer.
As the air in front of a vehicle is diverted around the wheels, a vortex vacuum is created underneath. Thus, allowing air to enter through the radiator opening resulting in a cooler engine and less drag on the front of the vehicle.

Since the air flow through the radiator opening is critical for engine and
drive line cooling, by controlling the amount of air entering under the front
bumper an efficient air flow is achieved. A simple analogy is pouring liquid
to fast into a funnel. The liquid trying to exit is slowed and becomes
turbulent due to suction. By controlling the amount of liquid poured
into the funnel, the liquid passes through effortlessly. |

Magnehelic pressure gauges were used to determine under-hood air flow.
A censor on top of the engine, along with another censor between the frame
and oil pan were pointed rearward. Tubing from the censors to the low
pressure side of the gauges was installed.
As the air enters from the front, it passes over the censors creating a
suction. This method is used to determine how the air flow helps heat
dissipation. Our results with the unit lowered showed a 70% increase in
air flow over the top of the engine, with a 40% increase near the pan.
This increase produced a five degree drop in water temperature, which
indicates cooler operating temperatures, and longer component life. |
