Thread: Anyone run an Electric Water Pump on the Street???

Tweet

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....

Hi Bill, I was going to run an electric water pump on my LS6 454 in my roadster. The electric pump worked like a champ during the dyno runs and during the break in period at my engine builders. 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.

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....

and Kitz , brushless would be nice

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.

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
