Electric Water Pump? Pros & Cons

Seen my other Jackstand?
Well I think electric water pumps are capable of moving JUST as much water as standard ones, possibly more in idle and cruise conditions....the only issues I know of are the price and altering the pulley setup to exclude a W/P......and the fact that theyre only rated for a certain amount of operating hours for the motor to last. On a drag car would I run one? Absolutely. On a weekend warrior street car? Absolutely. On a daily driver with lots of mileage? Hesitant.

If you wire it up with a variable speed controller like a DCC like I did then it does varry the flow of water, and combined with a Mark VIII fan it cools my car awesome.
Most electric water pumps also have a longer expected life span than mechanical pumps.
I fear electrical failures and an overheated car. The horsepower gained probably isnt enough to really feel on the street and warrant the cost. I jus got a stock replacement ford racing pump which is brand new and it cools the car fine. The electric one as stated before might be worth it where every last horsepower is needed.
An electric pump means you have to have an electric fan, because there is no place to mount the mechanical fan assembly. That means you need a 3G or other alternator capable of 130 amps or more to power everything. Add on top of that the requirement of a pair of controllers to operate the electrical water pump and electrical fan and you would have some complex electrical wiring to install & maintain. Electrical expertise is not one of the top skills here on Stangnet, so if you are typical of most guys, you might find the whole process beyond your current skill level.
i have 50,000 on my meziere pump thats on my 347, i run a permacool 16" fan and a GM 140 amp-one wire alt with no problems at all, if you call meziere they absolutely approve of continuous street duty with they're pumps, how many people posting here have actually used an electric pump in street duty??? i have and it works fine.
what all did u need to convert to a gm 140amp? Im getting ready to do the same thing
There are no good things that can happen from having an electric pump for the street.
Just asking for trouble, and it won't be if, it will be when.
50,000 miles is like 45,000 more than most people get out of them.
They don't even get you enough hp to justify the $300. Put the money in the heads or something else.

i gotta agree with you here, i have a damn turbo under my hood and my mechanical pump with a stock rad did the job cooling wise. i just don't see the point of doing it on a street car. i had an electric fan die on me and it left me stranded, since then i keep everythin simple.

I have an electric water pump and there is more to it than just hp gains
-Cools a lot better at idle which is when most people have cooling problems
-I have the ability to run the water pump with the car off, cooling down the car in between runs for better E/T's!
-Looks awesome
-One less pulley to deal with
For a all out street car, buy a good mechanical
For a car that will see the track and the street both good amounts, but an electric.
You don't really every need an electric pump, just some added benefits over a mechanical if you need them aka those I mentioned above.

88 gt 50 and 2000xp8, what kind of electric water pumps have YOU used personally on the street,since YOU'VE obviously had such bad experiences with them please share the maufacturer of the the pump that has let YOU down so that no one else gets stuck in YOUR situation.. or are you just repeating what somebodys brothers best friend told they're cousin at they're uncle's stepson's cookout two years ago??? i had used a stewart stage two pump on my ranger because it was a shortend version with big flow and severe duty bearing and such, the problem with big volume pumps is that they dont flow as well as a stock at idle, has to do with impeller design just like a turbo or centrifical supercharger etc, any thing over idle and they flow respectively more so much so that at 6,000 rpm with my stewart pump i was moving so much water that it was rupturing my heater cores, if i slowed the pump down (with a larger pulley) it wouldnt cool at idle ... see what im getting at here.... electric pumps have they;re impeller designed to run at a specific rpm, thus the efficiency of that impeller is nearly double that of a mechanical pump, the electric doesnt have to operate any where from 800 rpm-6,500, it is probly set a 3,450 rpm and all the cavitation,turbulance and flow distribution problems can be corrected if your working without the variable know as rpm., as for the issue of electrical failures stranding you ... get over it, your whole car operates off of electric, its obiously not an issue for your electric fan,fuel pump,radio,computer,coil,tfi,wipers,radio,lights,etc. and jrichker- meziere pumps come with a dummy pulley built into the pump motor that allows you keep all you pulley hardware and stock belt, and speak for yourself, I am qualified and have "electrical skills" just swaping to an electric pump DOESNT demand a new alternator, the pumps only pull between 5 and 7 amps, probly less than your stereo, and you dont need seperate controllers, have run when your ignition is on just like anything else, not doing that can cause steam pockets or boil off inside the motor if the pump doesnt run, then those incompotent users spread false rumors of how the product is junk.. the GM alternater is identical so the early for pivot type except the pivot on the gm is 3/8 and the ford is 7/16 so just drill the hole out and run a 4 guage(or larger) wire up to your battery or battery side of your starter selinoid
Every electric water pump I have ever looked at has had more than twice the life expectancy of a mechanical pump.
I have a Stewart's Components remote mounted electric water pump on a daily driven GT with a Mark VIII fan and DCC controller both and the car cools awesome.
Most electric water pumps flow much more water than mechanical pumps as well.

i just put a meziere pump on my car and its top notch! i only drive this thing maybe 2,000 miles a year so it doesn't get extended use like a daily car. i haven't put many miles on it since i installed it but the motor did seem to rev a bit more freely without the mechanical pump. heres some pics!

I'm starting to see some viable information from people. I dont see why the electric water pump would be unreliable anyway. Like ranger said everything on your car is electric why worry about a water pump. I think it would be beneficial to have an electric water pump if your sitting at a stop light on the street with your bored motor and the a/c on you can watch that temp gauge creep up. If you have an electric pump it flows the same at idle or upper rpms I assume so it would be beneficial.
