Electric fan?

Hello,
I know this has been covered but can't seem to find the answers I need. Help!
I have a 2007 Tacoma V6. The engine/cooling/radiator fan draws power directly from the engine which takes horse power. If I were to replace this fan with an electric model, would I see any throttle response in take off or lower speed gains when passing? Would there be an increase in MPG. Has anyone done this?
Thanks.

 

Ok, sounds good. Since i do tow a boat, I think i will leave it alone.

 

As Chris was saying Fans have come a long ways from what they used to install, you should have seen some of the goofy things we tried in the old days such as flexy fans which were supposed to straighten out the blades at high speeds and reduce drag, most ended up grenading and throwing hunks of fiberglass around the engine compartment.
I've only run with one guy that went with an electric fan and it wasn't because he was chasing horsepower, it was because shortly after he dropped a small block Chevy and an auto trans in his CJ he was crossing a stream and hit a hole which dipped his fan under water, fans don't make very good propellers and the blades bent which trashed his brand new Tranny cooler.
He ended up installing an electric with a switch on the dash so he could shut it off.

 

I have had v8 tundra’s and v6 Tacoma’s and it always seems that in the Tacoma’s there is power loss some place when you start off from a stop. I am not talking gunning it, just normal acceleration. So, I was thinking it was with the fan. I guess it could be a heavy fly wheel.
