water pumps

[bugsyc]

What is the general concensus about changing to an electric water pump.Is it worth it to regain the parasitic loss???Which pump would you go with???Miezer? model?? inquireing minds want to kmow

[sailsmen]

You put an electric pump in place of a mechanical one but they both have a pulley being turned by a belt?
Doesn't make any sense to me.

Yes but the electric pumps pulley is just an idler pulley, where as the mechanical pumps pulley is driving the pump(impeller)!

[SC Cheesehead]

There are quite a few guys running them with no problems, not certain the performace gains are worth the cost, IMO, but that's just me.

I know. I don't think any potential gains offset the costs and downside. What is the life of the electirc motor?

The EMP is a better choice.

Agreed! those electric pumps are very pricey, but i would like to have one:cool:

[CBT]

I have one I got from Mmatt, never installed it. Probably never will, I guess I should post it for sellz, just another box taking up space.

You make a good point there! i know a few guys who have had to replace the electric pumps after they burned out, but they say they luv em!

I hear a lot about the emp pump, but i wonder is it realy any better than oem??

+1 on the EMP, if you're planning to change out the water pump for a potential performance enhancement.

A lot of info on the EMP in the thread I linked including the "laws of physics".:lol:

[MOTOWN]

Interesting thread, but still a bit skeptical

[guspech750]

I'd be afraid of the electric pump failing and not noticing the car overheating while cruising and listening to some tunes.

That a better than OEM pump could be designed or that an eletric pump makes sense for a street car?

[John Nero]

i have one in my car for a few years now - no problems - i have a led light hooked up under the hood and in the car that tells me the pump is runnung - i am guessing it is good for a few more HP - the coolent flow is the same at all rpms

That's prolly the most common concern I've heard raised about the electric pumps. They're pretty reliable, but the concern about failure seems to be an issue for a lot of folks.

Wow, read that thread in 13 minutes? You are the King of speed reading.

I dont doubt that the emp flows better, thats clear after looking at the impeller design, i just wonder if it truly has less drag, or not?

As for the electric pump i like it, but the price scares me away!

Unless someone has one in there garage they will never use:P

Same here.

You don't "gain" HP like when you install underdrive pulleys. You do "free up" about 10 HP with an electric pump.

[slickster]

Well it's also a good peace of mind mod for 150. If you ever needed to replace your pump this is what you should do. I will just for the peace of mind along with oil pump and t'stat

[Captain Dynball]

Main problem with an electric pump is it can randomly go out where as the mechanical pump typically has many warning signs.

I've seen mechanical water pumps go out with no signs too.

[slickster]

I would run a led like John Nero said and replace every 3years I'm sure it's good for longer then that. But then I'm that guy that keeps a constant eye noise ear and fell on things

[bugsyc]

Ford Racing does have an electric water pump.anyone know anything about it.reasonably priced... Part# M-8501-L54...$119

[MOTOWN]

I think its a good idea to keep an extra serpintine belt, and water pump in the trunk organizer

With extra fuses as well

Ford probably gets the pump from Mezier. This is the one I have installed.

Here is Mezier's website. http://www.meziere.com/ps-1158-1126-wp346s.aspx

I carry my OEM water pump, spare belt and tools on my organizer.

The pump you are looking at is a intercooler pump for a heat exchanger......

Did you notice any power

[fastblackmerc]

Not by the SOP meter :D

Haven't had it dyno'd yet.

[bolsen]

Has anybody dynod an EMP or Meziere? If the EMP is as good as the Meziere, that is what I will go with. I can't justify $380+ on a pump without proven gains. You can purchase Cobra intake cams for $200-300 with a proven 20-30hp gain. Seem like a no-brainer to me.

You are correct, but it should take you less than an hour to replace the water pump. Including burping the system.

As for proven gains, search the many Mustang forums.....

I could not find a before and after ewp on a modular. Lots of ls1 etc info on them. 10rwhp with pulley. I've also seen some ewp's that would last a few months or less and cook motors but nothing bad about the melzer or stewert. Blackend has had the melzer for 3 or so years now with no problems. Idk if it's worth 350 maybe a last resort if your really bored but I would still have something wired so that i would get a warning light and a loud sound if it fails. Or just be happy with udp

I'm running a EMP pump for the last 4 years with zero issues. I just do not trust my engine to a electric motor that has to constantly run for hours on end.

If I were to replace mine I'd go with the EMP. I just can't trust an electric one. The only benefits that I can agree with are I'm sure it does free up some more power over the EMP and that you can run it with the car being off.

[sailsmen]

45K+ on my EMP.

[omarauder]

On the street, wouldn't any gains made by eliminating the mech pump be replaced by the loss you get by increasing the power into the alternator in order to generate current to drive the electric pump? Or am I missing something?

[fastblackmerc]

The alternator doesn't have to put more voltage out. The water pump runs off a switched circuit from the battery.

So yes, your missing something.... :beer: :D

Someone had a good post about, I believe it was called, The Big 3 Upgrade. It had something to do with upgrading the size of the positive cable and 2 other wires to compensate for a bigger stereo system in thier Marauder. I asked back then if a side benefit would be running an electric water pump and it drawing less juice. I can't recollect exactly. I will have to break down and use the search function, see if I can find it.

I've done the upgrade from the stock wire to 2 & 4 gauge wire.

[TooManyFords]

The reason I went with the electric pump is so I can hit a switch and turn both the pump and the electric fans on while the car is not running in the pits. This speeds cooling down the motor.

For a DD, I would just use a factory pump.

I've got one available but not in a garage. PM me.

Agreed, the voltage will stay regulated to 13.6 - 14 volts, but the alternator will have to supply more amps to run the motor. Volts x Amps = Power = Horses..
It could be that the electric motor route is more efficient than the mechanical pump, saving power that way. I'm only considering a DD where the electric motor would have to run continuously while the engine is running. For racing it would probably be different..

[warren]

Just had my Miezer rebuilt after several years use.
Factory tested 11 - 14 hp gain. Makes it real easy to burp
your cooling system because you can run it without the engine on.
Gor mine from Dennis Reinhart originally.
