How much horsepower does electric fans add?
In a normal pickup situation, even in high ambient temperatures, the electric fan system will only draw a maximum of about 5 horsepower from the engine. This significant savings improves fuel economy, and, in turn, reduces emissions while improving vehicle performance.
How do you size an electric radiator fan?
When it comes to diameter, you should get a fan that covers as much of the radiator core as possible. Measure the area with the existing fan and shroud removed to find out how much room you have to work with. Larger fans will keep your car idling in the heat for longer period of time without overheating.
How many amps does a contour fan pull?
Similar to the Mark VIII fans the Contour dual fans draw ~32 amps and spike close to 100 on start up.
Are electric fans worth it?
Although they will place an additional draw on the electrical system, they are a more efficient alternative to mechanical fans and don’t cause the dreaded parasitic horsepower loss. Here are a few other advantages of electric fans: Consistent cooling—they maintain their airflow at all times. Reduced water pump wear.
What is the main advantage of having an electric cooling fan compared to a directly driven fan?
A key advantage of electric fans is increased engine cooling and improved air conditioning cooling at idle, when it is most needed. In addition, replacing an engine-driven fan can increase horsepower and improve fuel economy as the engine drag from turning the fan is eliminated.
What size electric fan do I need?
As a general rule of thumb, follow these minimum cubic feet per minute (cfm) ratings when using an electric fan as the primary cooling source on a basic engine: 1,250 cfm for a 4-cylinder. 2,000 cfm for a 6-cylinder. 2,500 cfm for a 8-cylinder.
Is it better for radiator fans to push or pull?
A Push configuration is more efficient in cooling when its blowing cool(er) air from outside the plenum through a radiator. A Push also makes your build louder. In Pull configuration the fan or fans are drawing an air stream out of the radiator.
Why is an electric fan better than mechanical?
Electric Fans An electric fan completely removes the mechanical load of spinning the fan from the engine. It places an additional draw on the electrical system, but this is a more efficient means of spinning a fan, and it has a smaller impact on engine drag.
How do you upgrade a cooling fan on a 1993 Mustang?
Upgrade the stock cooling fan on your 1979-1993 Mustang with this Contour electric fan assembly! From the factory, your Mustang has a single fan blade attached to a fan clutch that is bolted to the water pump pulley.
How many CFM does a Ford Mustang fan have?
Combining approximately 3,500 CFM fan output into a compact, factory-style assembly was a very attractive choice for 1979-1993 Mustangs looking for a cooling upgrade. This fan assembly measures 24-1/4″ wide, 16-3/4″ tall, and is 3.5″ deep.
Where is the fan blade on a Ford Mustang?
From the factory, your Mustang has a single fan blade attached to a fan clutch that is bolted to the water pump pulley. This causes parasitic loss as your engine has to spin the assembly and as you modify your engine this single fan blade has a hard time keeping up with the demands of your newfound power.
Can a Ford Contour fan be upgraded to an electric?
Contour Fan Upgrade Converting the stock cooling fan setup to an electric fan from a Ford Contour or Mercury Mystique has been a popular upgrade for Fox owners since the late ’90s. Combining approximately 3,500 CFM fan output into a compact, factory-style assembly was a very attractive choice for 1979-1993 Mustangs looking for a cooling upgrade.
