Randall, Please tell me if this is wrongheaded thinking. First I bought the 12" fan because *they* said is was the correct one for my car. Going past that, the stock fan (yellow plastic not stock/stock) is 12" and has 56 sq in of blade area and the electric has 42 sq in of blade area. Both fans have similar pitch. Can't tell you the degrees as I just lined them up with a T square and didn't go for the protractor. The electric has a more *efficient* blade configuration, but this is where I think the electric is superior. The stock fan is limited to the air movement by the rotation of the engine at idle. Let's say 800 rpm whereas the electric is 1800 rpm. Will I not get better results from the electric for the same diameter fan considering the 25% reduction in the blade area? Am I just plain dumb for not putting on both?
