Do electric fans improve HP output?

I knew it was a savings but never really looked in to how much. I run SPAL pusher and puller fans, one on a toggle switch and one on the AC switch. Both route through relays. Id also be curious on their ALT only cost 1hp. From the pictures it was run on a dyno and only had the fan and whatever for distributor I'm guessing. I run a 180amp ALT so would all things being equal, use less HP since its working less?

Now for elec. water pumps and how much are they worth. I've been wanting to run one for a long time on the street. Some have had great results and others not so much so its always 50/50. With the fans above and my current system. I idle in Florida sun with the AC on all day and dont go past 185*.

I'd always wondered about an electric water pump too, but I was always hesitant on how much power it'd draw and if there would be any kind of savings.

So we change out the water pump for an electric, swap the fans for electric, lose the power brakes, ac, and power steering...

1000hp?

Nah, but when you have a smaller engine, electric fans do make a difference. Unless you have a track car, you don't want to give up the creature comforts.
 
Cast iron VS alum water pump might make a little difference on heat dissipation but wonder what they do for HP?
 
Back when they first came out electric
water pumps were considered track only
items. Is that still the case?

As far as I know, the answer is yes, track only. While they will be ok for limited duty cycles they don't pass enough water to be effective for all driving conditions. I will look into this a little more. Good question.
 
I didn't read the link but Less gas used but more strain on the vehicles electrical system and with EV's they have no need for a WP
 
After reading parts of the article I guess EV's do use electric WP's ?, also just love reading "Asias Rising Disposable Income"
 
For our cars, with original small block, there are these:
50 gpm does not seem like enough to me but so far I have been unable to find a comparison with the flow rates of mechanical pumps.
The other issue are the lack of fittings for heater hoses.
If one were to use a pump as shown in the BMW video how would you adapt a set of hose fittings to the front of the engine?
Lots of issues here.
The additional electric power required would lead to wire harness additions and changes as well as a different alternator.
