After reading all five pages of this, the newb has a question. I understand it takes a little bit of gas to run an electrical device such as an electrical fan but surely it takes way more horsepower to run an engine mounted clutch fan. Even when the clutch fan is in "neutral" it still is 8 (my f150 truck) pounds of rotating mass. I imagine eight pounds of rotating mass takes weigh more energy to move than an electrically driven fan. Just my thoughts though.
