Meziere Electric Water Pump

[crouse]

What's the deal with the Meziere Electric Water Pumps. Are they worth the money? Where's the best place to buy one? Any issues? How long do they last? Thanks, Curt

[DOOM]

They suck!!!!

[sailsmen]

No, why not go with an electric oil pump? How about an electric engine?

Any minor "benefit" is far out weighed by costs and a lack of durability.

You'll get a lot of pro's and cons. IMO, save the money. If they fail then you are dead in the water, a mechanical waterpump even when the seal fails will still get you home. Not only will you have to spend nearly $400 for one, but then you'll have to wire it up and install a LED on the dash to be certain its even working. All that for 10hp. A EMP waterpump will free up horsepower and costs less then half for the Meziere with less hassles or risk.

Is it a track only car? If not stick with a belt driven pump.

[bolsen]

Yeah, EMP's are supposed to be the ****.

That's what I have on mine! :up:

I had a meizere fail on me before! :down: :mad2:

OEM until it goes.......

OEM until it goes.......

I replaced my pump as a preventitive measure. Only $30 and peace of mind.

I think Zack mentioned using the Cobra water pump...anyone remember the details?

Has anyone ever posted about a stock water pump going bad?

I don't know about Marauders specifically but working as a mechanic I've only replaced one water pump on a modular and that was on my own CV at ~190K and ~20 years.

[Blackmobile]

I think that answers the OP question!

Thanks for the responses. I do have the Stewart Warner EMP water pump, so I think I'll stick with that.

i have never seen OEM WP go bad on any mod motor.
the only way i would replace one is on 150k miles one.

I read that the Aviator has the better water pump for the 4.6 4V...

I'm running an Evans water pump FWIW

[John Nero]

i have an electric pump for over 3 years - no problems

I have 2 years on mine... no problems.

I have 2 years on mine... no problems.

7 years on the mach1, no problems. Then again, it hardly ever moved in the last 4 years or so.

The benefits, beside the hp freed up are these - better cooling in stop and go traffic as it's not based on RPM, it flows constant. This was noticeable in Arizona heat. And if you're so inclined, you can wire switches to turn it and the fans on in the pits at the track to cool down between passes. Also, I see it as an alternative to underdrive pulleys, with the added benefit that you don't have to set the idle higher and the alternator wont struggle to supply the electricity at idle.

[massacre]

Another benefit is at the drags, with an electric cooling fan and elec water pump, you can cool down between runs.

I had mine on for a few years and never had any problems, if you are looking for every pony you can they are worth it. They are a little more involved to install but mine worked very well with no issues.

Would also like to hear more about this.......

[DOOM]

Just a matter of time.

Will happen quicker on a daily driven car!

+5!

I've had mine on since 2005 and had no problems.....except those created by a loose relay = my fault.
Even if you don't notice your temperature gauge, the engine management system will let you know if the Meziere pump has failed.
The computer pulls so much timing from the engine as it gets hot that the car suddenly feels like a dog!....That will force you to scan your gauges while saying "WTF!?"..and see the high temp.

Also, mod motors from 99 and up (I think, might be earlier) also go into an alternate firing limp mode where it takes turns in firing each cylinder, instead pumping nothing but air thru each cylinder every other ignition stroke, allowing the engine to limp to safety with minimal heat created. If you don't notice the timing pulled, you will be noticing 4 missing cylinders... ;)
