Hello Everyone! ;) Anyone here run {or have any thoughts on running} an Electric Water Pump on the street??? And if so, what make are you running??? Although my car is a daily driver I don't really drive that far from home {& I have AAA for towing ;).... Probably put 100 to 150 miles a week on it. It's a small block Chev in a '32 Ford. Summit has a 'street' one that looks JUST like a regular water pump with an electric motor on the front. Thanks all, Bill
I don't, but had thought about it about a year ago. Then I read an article by one of the companies that make them, and they advised against it. Don't remember the article, but something about the fact that the electrics were primarily designed for short trips, e.g,, drag racing and not everyday driving.
Probably someone here that actually does use one.
Most newer cars use them....Quote:

However when I installed the BBC in the roadster the electric pump was 3/4" too long so I had to switch to a Edelbrock short endurashine water pump. Now I have a practically brand new shinny chrome (except for dyno time) electric water pump laying around gathering dust. Guess it will be a paper weight if I cannot sell it. I sure wish I could have used it and my builder was very impressed with the way it cooled my roller BBC. Needless to say if mine would have fit I would be running it, but if you use one make sure it does not move TOO MUCH water because that will not give the h20 enough time too cool because it is moving so fast, but I'm sure you know that! Happy rodding.
If I ran one I would want it to be a brushless permanent magnet motor. This means the pump will have to come with an inverter box as well. I have not seen any of these out there yet.
About the water flowing too fast. I have yet to see any test results or analyses on it but I would note the following facts.
1) Say one pump is flowing twice as fast as the other. The total time in the radiator is the same, it is just there twice as often for the 2x pump.
2) Water abosrbs and transfers heat via convection and faster fluid means higher convection coefficients.
3) At the extremes it would seem faster is better. Why? Well if you have no flow you know what happens. :LOL:
There is likely an optimum, however, if you have a restriction like a thermostat (and you certainly should on the street) IMO you will be hard pressed to get the flow up too fast.

I have used the Meziere electric pumps with good results.
StylinZ what brand is your pump?:)
I have read and heard that Meziere is a very good dependable brand off and also on the street. There are a couple other very good brands but there are a lot of cheap brands too . You get what you pay for....Quote:

I run a CSI electric pump. but only about 20 to 40 miles a week. I think most people that run them have high horsepower requirements, and dont want to loose the roughly 15 horsepower it takes to turn a belted unit. Plus the down side of a belted unit is at high RPM they cavitate the water at the inpeller and do not flow at a proper rate. The electric units flow at the best rate at all times, no fluxuation. But to answer your question Ive not yet had a problem, car stays very cool.
...Thank You Bob, Bigtruckdriver, Jon, Geezer & Mooneye! So some new cars use them? Interesting.... I measured & there is room between my engine & radiator.... Yeah my car runs so cool now that I drove 25 miles w/out a fan belt the other night & it didn't heat up at all {ah, but it didn't charge very well!}....... Thanks again everyone! ;) Bill
Old post, but I am needing to run a electric water pump on the street. Would take to much typing to tell why, on other words to many pulley isues trying to get the mech. pump to work :LOL: So Was looking at A Mezier that flows around 55, or could I keep my mechinal pump and mount a belt driven motor(moroso unit) on it? Or run the good electric. Application is around a 600hp 427bbc blown, 6lbs boost, 8" convertor, hopefully my chopped32 alum. radiator can handle it. And I have still not cranked it :D
I was surprised one day to see a local T bucket running an electric pump, I always thought they were just for 1/4 mile race cars. I asked the guy how it worked and he said he bought the car that way and had put a lot of miles on it with no problems. I wonder how much they draw.

Having mechanical interference is perhaps the only reason I can see to run an electric water pump. The Meziere 55 would be my choice.Quote:

The one I was looking at draws 10-12 amps, I have nothing but a starter in my car, running a Magento so I have plenty of amps to spare:3dSMILE:
I would stick with my mechanical , but to many clearance issues. Just looking for some feedback on a good one.
I am using a CSI on my roadster with no problems at all. But i have not been very many miles. but I have drove it in the heat of the day here in Texas with no problems at all. CSI also says that they are great on the street, but I guess they would say that. Like mine so far
