Title: Electric fans
Post by: Rez Zuki 87 on January 18, 2011, 07:56:36 PM: What kind of horsepower gains would I get if I switch to an electric fan?

Very little. If you have a viscous coupled fan then it spends most of its time free-wheeling, it only locks up when the engine gets hotter than normal, at that point you will gain (or not lose) maybe 2bhp, with a corresponding improvement in fuel consumption. The main reason for retro-fitting an electric fan is that it can be disabled when wading which prevents water being sprayed all round the engine bay.The viscous fan also wears out pretty quickly when being used as a propellor.

One item to remember is that a huge percentage gain may be barely noticeable. 2hp doesn't sound like much, but it's a 2-4% gain in power. The same with mileage, if you gain 2.5% then (for me) it's a mighty .75 mpg, or 7 miles per tank. When you think about it, 2.5% is a huge jump in efficiency for such a small amount of work.
