Just wondering if anyone uses a Meziere water pump of any other brand on their car?

http://www.meziere.com/

I've talked to a few people about this product, they seem to really like it in the summer time, but hate it in the winter time. Why? B/c for some reason the flow rate causes the heater in the car not to function. lol Not sure, what exactly is the case, but I'm just want to know who's had some real experience with these devices and their comments and recommendations on them.

Also if there are any other brands out there.

 

becasue the more flow makes the water/coolant not able to be heated enough for it to produce heat for the heater when it runs through the cpooer pipe in the heater core.

i wouldnt see the point for NA.
it could actually cause less cooling also. by what i just said.

 

i ran one on my car for a while and liked it. ya it ran so cold the heater wouldn't work. it did make a noticable diffrence in power too.

 

For a street driven car, the OEM waterpump is fine.

But for N/A drag guys, the gains from freeing up parasitic loss from the mechanical water pump is more important than keeping cool for 10-11 seconds.

 

evilxkid- what was the car used for w/ the elect. h2o pump? Daily driving, drag race, auto-X? Did you have a coolant temp. guage to see the change in temp.?
Thanks.

 

Are there any other brand out there that offer adjustable flow?

I'm not trying to freeze in the winter time!

it was in my daily driver. i drag race it on the weekends and arround town. i never had an after market gauge in my car so i don't know exact #'s but when it would warm up the stock temp gauge bearly registered at all. and affter driving arrould i could touch my valve cover and it would bearly be warm. if that helps.

i sold it to my friend and he's been running it for the last year. i'll ask him what his temp gauge reads. his cars turbo and runns hotter though.

 

I'm not using a pump IN THE CAR yet but I am completing the design of a digital PWM (pulse-width-modulation, like the fuel injectors) temperature/speed microcontroller system for a 12-volt electric water pump. That's the biggest complaint I hear from users - that the thing runs full power ALL THE TIME - or they have to switch it on and off constantly.

This system will run the pump AT LEAST 10% duty cycle no matter what - up to a full 100% depending on cooling needs.

Inputs: water temperature, tps, rpm, desired engine temperature (up/down set buttons and two presets (cruise/full for staging lanes).

Outputs: lcd temperature status readout, electric water pump, radiator fan.

System uses fuzzy logic (learned and stored in EEPROM) to determine best speed for different load/rpm combinations at given water temperatures. Also has redundancy into the system so the high powered 8amp final output can be automatically relay switched to ON in case of failure. Better to run full cool than not run at all.

It's all going into my new B21C5 next season - LOTS of custom digital systems to assist in hauling *** down the 1320 and through the cones. Gonna hit 11.999 on drag radials with full-looking interior (two race seats, dash, all panels, carpet). Replaced HVAC console with guages; replaced audio system with this console:



Anyway, I don't want to threadjack - but you DO need some sort of electronic management for this thing to work on a daily-driver.

Lata!

if a daily driven car, stick with a stock water pump, the life of the electric ones average 3000 hours ... for a street car thats daily driven I dont recommend using it, for a race car I do ... only because of the balance between HP/temp decrease vs. practicality is not worth it for a daily driven street car.

I use it on my street car but the car is driven on the weekends (for street/track racing, etc) ...

don't you also run ~15:1 static compression in your "street engine", Greg? (BTW, i love that thing.) i guess in metro Detroit, we also get 110 octane at some stations, so it is 'pump gas', but the lead can't be so good for cats or emissions.

 

In the near future Im gonna be switching over to a manual steering rack in my SE-R. Im gonna be taking all the spower steering stuff including the pump and that means that I will no longer have a belt tensioner for my water pump belt so Im switching over to the Meziere unit. They make one for my car and from what Im reading good thing I dont drive it everyday.

LOL thanks slofu, that is true ... but you know I'm being honest saying I only drive the car on weekends, as oppose to some people who (claim) they drive their super high compression setup cars daily to work and home LOL ...

yea this water pump is suppose to be crazy. like makes a little more whp across the whole band from wut i have heard but i heard some people going off about it if its a daily driver but forgot why. i also heard that you have to take out the whole engine if you want to install it. damn i can't remember too much but they were saying like you have to turn your car on and idle it for a while because it would be too cold. i dont remember exactly whatever but yea....

 

can we get some pics of these installed?

 

what kinda flow rates do these have, in GPH?

 

???
