The airflow at highway speeds should keep the engine below the turn-on temp of the electric fan.
I dragging this one up to see if there has been any new thought or experiences on this subject.
I've just done a bunch of searching and read both Deuce forums and ended up with about a 50/50 mix of opinions.
I read that the Deuce fan costs about 13 horsepower (+/-), and since I'm doing mostly driving on the 4 lane, an electric fan might give me a couple more MPG's.
Does anybody have any REAL experience with one? Good OR bad.
Size?
Cost?
Where at?
This thread indicates that : a pusher didn't work well ... but a puller just might. 3600 cmf seems to be the amount of air needed ... and two fans combined might be the best way to get that kind of performance.
BTW ... I DO agree with Jason that on the Interstate the air at road spped should be sufficient to cool the engine ...
BUT ... going up one of the long Georgia draggers ... well I can see the fan coming on to help out.
I do see that 12 VDC fans are cheaper than 24 VDC even if you include the cost of a 24-12 step down converter. Since the fan don't run unless the engine needs it ... and then it shouldn't stay on for very long ... I don't see a problem with the charging system.
I don't ever see me sitting with my truck idling for two hours.
I ran my MGB's with only a toggle switched electric fan for years. When I was racing them ... I never turned on the fan at all unless I was sitting waiting to go on the track.
But then ... a MGB ain't about 1800 pounds of hot cast iron LDT either. That's why I'm asking.
