The Principle Behind the Cyclone
A stock engine fan clutch is designed to operate continuously, regardless of drivetrain temperatures. Whenever the fan is operating it is a parasitic draw on both horsepower and fuel economy. The Cyclone Power Fan is designed to recoup this continual loss of power and performance.
Extensive tests on Ford V-10 and PowerStroke vehicles show that the engine fan on these vehicles are typically needed for cooling only 2% of the time. In normal driving conditions, 98% of the time, ram air is sufficient to keep the drivetrain cool. the fan is needed when outside temperatures are excessive, or when a vehicle is sitting stationary for a long period of time. In all other operating conditions the fan is simply a drain on power and fuel.
The Logic of the Cyclone
The Cyclone is designed to automatically disengage the fan when outside temperatures and normal ram air is sufficient to cool the drivetrain. Remember, most of the time there is sufficient air created from normal acceleration to keep the engine cool without running the fan.
The Cyclone also will engage the fan, when operating conditions warrant added cooling. But unlike the stock fan clutch, the Cyclone Power Fan synchronizes the fan's rotation to each engine revolution, spinning it much faster than the stock fan clutch. This improved technology provides much improved cooling to the engine and transmission.
With the Cyclone installed, there is a marked difference in air conditioner performance. There will be a dramatic increase in coolness and improved air volume.
Fluid Thermistor Control Unit Harnesses The Wind For More Power And Performance
The Cyclone Power Fan replaces the factory, or original equipment, fan clutch. The O.E. fan clutch is controlled by changes only in air temperature. Working on the same principle as an electromagnetic air conditioner compressor clutch, the Cyclone Power Fan completely disengages the stock fan or engages it on an as-need basis as determined by a state-of-the-art, fluid thermistor control unit.
The attractive control unit is conveniently mounted in the cab and has two main features: 1) a manual override option to activate high-powered cooling control and, 2) thermistor fluid sensors that read changes in outside temperature, engine coolant and transmission fluid temperature. As the outside temperature rises, throttle position changes, or as coolant fluid temperature changes, indicating stressful operating conditions, the Cyclone will engage the fan for added cooling to the engine and cab. A highly visible power light on the unit indicates when the Cyclone has engaged or disengaged the fan.
New Technology Reaps Rewards In Power And Performances
When the fan is disengages, expect a significant increase in horsepower and fuel mileage. Dyno tests repeatedly show gains of 40 more horsepower and an increase in fuel mileage on Ford PowerStroke and V-10 vehicles.
Downhill braking performance is improved with the Cyclone. In downhill towing when braking is most stressful to the vehicle, use the Cyclone to manually engage the fan and safely add powerful retarding horsepower to slow the momentum of your vehicle.
The Value Of The Cyclone
The Cyclone Power Fan is a better overall value than either power chips or performance headers and exhaust systems in delivering horsepower, performance and fuel savings. Priced substantially less, the Cyclone delivers the same increase in horsepower and fuel savings, but only the Cyclone delivers improved air conditioner performance, improved cooling to the engine and transmission and can assist with engine braking.
The Cyclone has a big performance impact for a relatively low price. Unlike performance power chips, the Cyclone does not need calibration. And unlike performance exhaust systems, the Cyclone does not in any way effect emissions.
