yeah, the electric freed up a couple of horsepower, but what good is that when you're stuck in a traffic jam, or hot lapping, and the temp is ratcheting upward? i'll gladly trade 10 hp for stonewall reliability.
The electric fan moves the same amount of air whether idling or high rpm. However, the mechanical fan is moving MUCH less air at idle, which is exactly when you need it the most.
Fan clutches help by slipping at higher rpm but now there's another source of reliability problems.
What kind of "hot lapping" are you referring to?Any time the car is moving over about 20 mph the fan only gets in the way. If you're overheating while moving, either the airflow through the core is insufficient, or you don't have enough radiator. The type of fan won't matter here.
Finally, it's not "a couple" or even "10 hp", didn't you see the fan test article (and other similar tests)? Would you gladly give up 30 or 40 hp?
