its like a hood scoop (N/A)on a dyno = useless

hate to say it but your .02 is wrong. turning the fans off while going down the road will cause your temp to rise. No matter if you are going 55 or 110 all motors generate heat and still need some sorts of added fans to pull or push heat from the rad. air flow alone is not enuff to cool the system down. I have felt the proof of this recently. loaned my car to a friend. fuck ass didn't turn the fans on while going down the highway. popped upper rad hose. as well as blew my damn head gasket. ~true story.
As for the debate P.K. and I where having. I will agree on the loss of power w/ electric fans to an extent. thinking about it. if electric fans are not cooling the system
efficiently and have to remain on for the duration yes. they can cause a power loss. Yet that same thing needs to be in consideration for the clutch fans.
How ever either way. the whole cooling system needs to be taken into effect. what rad is the car running. what size are the fans,
"clutch (OEM / HD, does the clutch using OEM / flex) or electrical (power drain of fans, 1 or 2 speed) , cfm's, coolant ratio and coolant additives, thermostat temp, does the car have any other sorts of letting heat escape from the engine bay. All these little things can play a part on cooling and power loss.
I don't doubt your dyno charts that you have. Tho I do wonder on how much detail was taken into effects when obtaining your information. even simple things as temp of each day, humidity levels, was there a breeze blowing into the shop. can make a difference.
If I as still down in Fl. I would be willing to spend a day or two in breaking the myth of: which is better electrical or clutch.
feels like lighting just struck my brain we should email the myth busters.
