Quest for 7's in the 1/8

If it will fit.....Why not!

Now, one of them Hmmmm thoughts.........
With the fan being lighter, will it engage sooner????
Putting a thought to my own question............................I think the fan blade trying to pull the air will be more resistance to the fan clutch activating then the weight!.?.....
So if the plastic fan pulls more air then it might not help.....maybe even steel a little bit of HP.

Maybe I'm way off base.
Valid Point, in my Humble opinion
