Electric Water Pump

[Mopar Thunder]

Where is the best place to get an electric water pump for a small block?

[Chryco Psycho]

Mezire is probably the top brand , shop for pricing

Thanks that's what I was thinking. I'll pass it along.  Seems hard to find shops that carry electric pumps for Mopars.

Try this. It's availabale thru Summit Racing. Not cheap at $425.00 bucks!!

  is right, I must havwe missed that in Summit.  I looked thru both Jegs and Summit and other places.  There just doesn't seem to be a lot of places to buy from. That is what my friend was looking for though. Thanks moparmanoiac59

Good chance the electric won't do the job! Had a Meziere on my 496. Had to go back to mechanical, but kept the electric fan on the alum radiator. Electric might give you 2 or 3 hp advantage, but improper cooling negates that.

Little bit of physics here. If you change a function from say mech to electric there is an efficiency loss there. Someone has to pay for that loss! So if you need 2 hp to drive your water pump then you probably still require the same hp to drive an electric pump doing the same job. Plus the conversion loss in heat and wind age losses on the alternator etc to create the electricity. Where the electric options work are in race cars where they do not run alternators and simply let the battery run down over the race. Then the 2 hp gained is a benefit.
Hope this explains things a little better!

An electric water pump would need to pull 57 amps to be equivalent to a one horsepower load on the motor, from past calcs I've seen.

With the first of many oversized meals consumed,...my thougths on this subject is as follows.

I hope you guys converting from mechanical driven fuel/water/cooling to electrical ditto, are aware that it is the ALTERNATOR that will be supplying the power....the battery is merely a reservoir/accumulator/battery

Therefore, with more amps running from the alternator, it is recommended to bypass the AMP-METER, thus connect the alternator output directly to the battery.
From the battery onwards most people have got it right....

Cudabob - your conversion is fairly correct. I was pointing out to people that trying these things are a big waste of money for a street car. Money is better sent on headers, cam etc.

Merry Xmas all

Oh, I agree.  Places like Mancini will tell you that you'll only save about 3 to 5 hp by going to an electric. I noticed on my 496 street motor that the electric, which moves at only one speed, cannot support my engine when I have the revs up around 5000 or 6000.
A much bigger savings is found by dumping the mechanical fan! But an electric fan really only works well on an alum radiator, per my experience.
