which electric fan?

btwilson86 · 01-15-2010, 07:04 AM

So I've been reading about electric fan setups that people have done on these cars, and I'm actually kind of curious how often the fan comes on. It would seem to me that cre would be right about the electrical load being substantial with the fans on, but what about when they're off?

I guess what I'm really asking is, are the electric fans off long enough for you to use the power gained?

My opinion... no. Read my addendum above. Neither should really cause any significant power loss when the vehicle is moving at any decent speed. Okay... I guess my answer would actually be yes... they shouldn't need to come on while the vehicle is moving BUT the mechanical fan shouldn't be placing much load at that point either (if any).

speculation versus experience

Whatever... the bottom line is that if anyone wants to convert they need to do it right. My opinion is just that, my opinion. My hypothesis are based on my experience with all of the various components involved in other applications. There are newer components both electrical and mechanical which are more efficient than the stock fan if for no other reason than weight reduction and reduced rotational mass.
