Thanks for the honest opinion. Most of what I have read from guys who have put on e fans has said "it gained me 3-5 mpg!" or similar unlikely sounding numbers.

My guess was that the fuel savings would be minor. That is why I decided to try to actually measure what the old belt driven clutch fan was actually using after getting the good suggestion/technic from ttoyoda. There is no accurate way for me to measure the before and after FE gain with a mod like this unless the gain is very large or unless you want to do an extensive A B A type of test. Again, my only need to know the FE gain is for pride/ego, since I had already spent the money. Thanks again.
