Electric Waterpumps

are there any good electric water pumps that are good for daily drivers or are they just for race cars?

 

Got a couple of friends with show cars and BBC motors that drive them on the streets and have electric water pumps. I have never heard them complain of any problems. I lean towards the old fashion belt driven pumps my self but if thats what you want go for it.

 

Maybe if you drive it from the trailer to the show field but if it's a real life driver you probably want something that will be easy to find in B.F Egypt when it breaks. Cars never break where it is convenient.

 

I've wondered about this myself and never found anyone that used one on a well driven street car. Until there is proof positive they are reliable I'll let Tommy's advice carry the day. I was never real comfortable in the last century and this new one is down right scarry.

I go in the 10's at the track with an old fashion GM mechanical water pump. Then I drive it home!!!!!!!!!!!

 

I want to build a car with the radiator hidden somewhere and dont want to run a regular water pump. Want to run a g***er style tank up front and without a grill shell.

 

I've sen a bunch of street rodders do this, and a couple of drag cars that do limited stret duty, I se them a lot, so it seems to work for them.

 

some of the oems are going to electric water and power steering. eventually they'll get to us,

 

So explain to me a little better what you want and why? You still need something bolted to the engine to keep the water in the block and perhaps an alternator as well? How about a water pump and no fan?

 

A company called "Hot Heads" has a rod with no front radiator or shell. I have seen the car up close, the radiator is in the back and cooled by an electric fan but I wasn't looking for a water pump on their Hemi. I'm sure that if you pull up "Hot Heads" website you will see their rod.

 

I had good service using a Weiand electric pump on a street car w/ big block chevy.

 

I used a Moroso water pump drive 20 years ago, worked well, kept the car cool, was full drag but I drove it on the street. I would run it for a while then put it out of service, had a tough time running an alternator with it turing the water pump, had trouble getting the belt to run correctly just crank to alt..

 

I was just reading about how much water you need to move thru an engine. And the rule of thumb seems to be 10 gal/min per 100 HP. Of course most normal driving is in a low hp range, probably like 50hp for 60 mph or something like that.

Years ago I had equipment with electric water pumps to move the hot water for big heating units. They were 12VDC marine pumps with 1 1/2" copper tube sized inlets and outlets. These pumps would run as long as the engines were on, And had seals similar to a car water pump. No problems except for the occasional changing of the motor brushes. And very rarely a seal going bad. Once in a while a motor would fry. These put way more hours on them than you could ever do in a car.

I would feel comfortable with one of these in a car as the main water pump.

looks interesting, much more wallet friendly than the Meziere Ent unit I was looking at for my 440...

I've actually been looking around quite a bit. There are remote units that have only a fitting in each water pump hole and a *Y* connector away from the motor then to the remote pump. That looks more like what I am after. I just wanted to see if they were usable for street driving without overheating problems.
