Electric Fan Hp Gain

Many electric fans can be pre set to turn on from between 180.

Electric fan hp gain. One of those periodic fads has hit jeep land where everybody is converting from the stock belt driven viscous cooling fans to electric cooling fans claiming to gain hp and as much as 1 0 mpg fuel economy. I don t think 10 horsepower is an unrealistic estimate of the power gain i realized. Its dyno proven that electric fans give you hp. I was very skeptical of the horsepower claims made concerning electric fans but after that short trip i was sold on the idea.

Make sure the electric fan covers 70 percent of the radiator core and moves enough airflow for the engine size a rule of thumb is at least 2 800 cfm for a 5 0l engine. It looks much nicer and cleaner in the engine compartment. The electric fan would be a cooling solution for vehicles that typically drive at low vehicle speeds with low engine rpm such as cruising. How much largely depends on how big your engine is and how fast your motor spins but it does give you power.

Yes it will take additional horses to turn the alternator when the electric fan is running but you will achieve a noticeable gain when the fan is static which should be most of the time that the jeep is moving street time. Cost is 100 for the fan. Slow off road and stop and go will cost you horses. Once your moving the fan will be off.

An electric fan won t switch on until you get stuck in traffic or idling in the driveway. Anyway the 4 7l and 3 7l have one electric fan that mounts to the radiator and fits perfect in the hemi rams and is even plug and play. 5 is not uncommon. A nice little bonus is an increase in mpg.

So you basically get rid of a clutch fan and a smaller electric fan in place of a new shroud single fan setup.
