electric water pump

[Bellevensian]

hey guys, i am planning on getting an electric water pump and was wondering if you guys knew of one that is significantly better without spending over 200 bucks. I saw one made by Weiland in JEGS but i dont know (quality wise) what brand is better than another.....................

Weiland aka Holley, I wouldn\'t expect low quality out of them.



I don\'t know a lot about electric water pumps, I really rarely see anyone use them and if they do it\'s not for street use. The others that I see are for solving clearance problems, but I\'m sure there\'s someone else with more knowledge than me that will chime in...

electric water pumps have a higher failure rate the mechanicals they also tend to stick out farther then a mechanical and they but a heavier strain on your altenator so no big stereos for you. I would recommend not using them.. there rgeat for race applications for faster rev up and because they dont get used as much as a daily driver.

so is it worth getting a larger alternator if i decided to get an electric water pump?

In my professional opinion stick with amechanical water pump it\'ll last you a f@#K of a lot longer and it doesn\'t rob that much horse power considering getting a larger alt will pull your engine down just as much if not more.

How many amps do you think the pumps draw? The motors look relitivley small. Ive never heard anything about them going bad but ive never seen many on the street adn water and motors dont mix well. I have heard of people solving big block cooling problems by installing them because they dont lose flow at idle. And if i rember car craft did a dyno test of water pumps, not on the engine but they made a flow and drive hp tester, even the best aftermarket pump drew around 8 hp a stock used ~12hp.

How many amps depends on the pump and how much coolant it needs to flow you dont see them on the streets because of the failure rate the pump continuesly pumps water at a given speed no matter how fast your engine is running so in order to cool for the higher rpm ranges it needs to be cooling at its highest speed all the time or as soon as you goto pass someone your temp will climb to quickly. in racing applications and dyno applications these are perfect because you dont need to drive any accessories with a belt.

[Bellevensian]

so thats why they fail on the street is because they run at a high rate all the time?

You got it!

They say it will run 5500 hrs. That\'s a lot of driving! Pulls 5.8A-not much if you ask me.

To each there own. Just one thing people will tell you many things to get you to buy there products dont believe eveyrthing. I\'ll give you something to think about for example to see if a pump would last 5500 means they had to run it continusly for 229 days now you and I know that they couldn\'t properly test this pump 24 hours a day because if it failed when nobody was there they wouldn\'t see it so lets say they do 40 hour weeks that means they ran it for 2.29 Years hrmm well the products been out for less then a year according to what Ive read about that pump... so how do they come up with these figure! well it comes down to the simple fact that the bearing used by the motor in there pump has been tested and can continuesly run for 5500 hrs until failure this is an example. so techincaly your pump may last more then 5500 hrs which could be a good thing but any electric motor thats self enclosed that sees a continues load and various conditions is not going to run for more then 550Hrs in reality. and Im sorry to say if its only drawling 5.8A\'s which is less then your head lights its not doing its job because no motor is that effiecent at pushing a load even a meager electric fan draws 15Amps and it Barely would take heat out of a rad so most automotive fans run 30A min because thats what it takes to transfer head from the rad to the air. and it uses an even smaller motor then that pump and can be stopped by hand. Do your research if they really are as good as they say everyone would be using them wouldn\'t they. I mean electrioc pumps are great for short cycle activities like racing but for day to day use under various circumstances they just wont hold up. A good example of a motor that does a good job is a fuel pump it runs in all kinds of circumstances lasts fairly long gets continuesly fresh lubricant ie gas and does have bearings but even they fail after time and still draw min of 8 amp to push a small amount of fluid.

Not to put down CSI in any way or form they make excellent pumps just remember there racing pumps not exactly for a daily driver!
