Does electric fan improve MPG?

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.

What is the advantage of a flex fan?

The biggest advantage to flex fans is their ability to pull more air through the radiator at an idle than a clutch-operated fan. This is particularly useful on engines running high compression ratios that are more difficult to cool.

Are Flex fans better?

For high rpm use, flex fans are considered an upgrade over clutch fans. They can be a good choice for modified vehicles turning 6,000 – 8,000 rpm. Advantages include: They move more air for better cooling.

Do electric fans add horsepower?

We’ll jump right into the heart of the matter: An electric fan is the better performance solution, freeing up maximum horsepower and mpg.

Do electric fans increase horsepower?

What is the difference between a flex fan and a clutch fan?

Flex fans don’t use a clutch and therefore operate at 100 percent of water pump speed, making them more efficient than clutch fans. Considered a step up from clutch fans, these fans are typically lighter than clutch fans and often feature blades that flatten out at higher rpms for greater efficiency.

Are electric cooling fans better than Clutchfans?

Does a clutch fan Rob horsepower?

The answer is there is no difference. If your fan clutch is operating properly, and the fan is not required there is minimum drag, almost insignificant. If the fan is required the clutch kicks in and the fan uses maybe one or two HP to turn it.

Are electric fan conversions worth it?

Switching to an electric fan helps 2 ways. It improves FE, and it frees up power when you want. My F150 has had no fan at all for about 3 or 4 years now. It rarely is sitting still in city traffic; as long as it’s moving it’s been fine, even when working hard.

How much HP is lost from a fan?

More typical was a loss of between 13 and 19 hp between 3,600 and 5,900 rpm (see Test B). The accompanying charts reveal that the average power loss with just the simple engine-driven fan was 18 hp or an average of 6 percent across the entire powerband!
