Im sure it already been ask but

does an electric water will keep up the task in a street car
why I ask is my brother have a chance to buy a new one
for almost nothing and he ask what was I thinking about that

I never ran one so hard for me to tell but I told him
that I will ask FABO the question
and Im sure I will have the right answer


thanks Bob
 
They, sometimes work on limited use street cars (to the burger joint and back). More than often they lead to a "Why is my car running hot?" thread.
 
And now, for a short, true, somewhat funny story.

Back in my Navy days, I had a '64 426 Dodge. I tore the dash out and built a custom dash. Went "downtown" to get the usual, common, standard, S&W black face mechanical gauges, only the joint didn't HAVE a matching trio!!!! This guy talked me into some Custom Crap S&W had just come out with and they didn't even have a mechanical temp gauge in them either, but he talked me into an electric one, AND I SHOULD HAVE FREEKIN JUST LEFT

Anyhow, I get this all installed, and the gauge runs right down on the cold peg. Now I had pulled the heater out of the car, so "no help" there

Anyhow after a couple? of weeks suddenly one day!!! the gauge!!! started reading "normal!!!"

EXCEPT THEN I noticed that it pinged "sometimes" and puked water when parked.

LOOOOOOOOOONNNNNNnnnnnnggggggg...............story short..................

I finally ended up pulling the rad, the pump, to inspect things. Everything looked "fine."

Until I tripped on the pump housing, and it "jingled!!!!" The pump had a stamped steel impeller and had rusted right off the shaft. That engine was running only on convection cooling!!!!

Amazingly, it didn't do "all that bad" except in slow traffic.

Better than a mechanical pump. They hold constant and consistant flow. Just make sure you get one that is rated for street use which referes not to it's ability to cool but longevity. I put one in my last car which has been primarlity street driven for over 10 years.

I used a CSI pump.



thanks Bob


A couple notes. An electric pump, at least in my experience wil tighten the gap between the radiator and the water pump. I used twin electric fans. The pump sat between them.

Started by someone who lacks knowledge or has made poor choices.

One more thing. Hook your power line to the pump to a light on the dash so you know it is receiving power. DOn't ask how I know that...
 
I just read the couple hundred threads about cooling issues we have here every year. Start reading those and you will know exactly what the problem is with cooling an a-body.
 
The main reason for running an electric pump is to gain HP, the mech ones obviously rob power from the engine, if your only running the car on the street there is little advantage apart from they look cool, and as 1968formulas340 says, your next post may well be "why's my car running hot?"
I'm struggling with my CSR, if your running low comp and iron heads you may be ok, high comp and ally heads doesnt seem to be a good recipe in my humble experience.
 
nope he s running a little 360 .040 over
.509 mp cam
10.25 cr.
and 915 heads

he bought a champion rad
he s suppose or wanna install bot in the same time

Primary reason to run an electric pump is to improve cooling. YOu don't gain much HP. It also simplifies your pulley setup or eliminates the need for pulleys completely on a drag car.

I ran 10.5:1 with aluminum heads on my 440 with the CSI pump. I had a be cool rad with twin fans. 180 thermo. NEVER had an issue.
 
limited use they are good. horse power had a motor in their dyno and started out with an electric and it did not keep it cool and went back to the belt by the end of the run.
 
have a friend that used to run an electric wp on his 74 cuda. ran fine for quite a few years. drove it quite a bit on the street. never really took it on long drives because it had 4:30 gears but a lot of local driving with a 26" rad and some taurus electric fan. car always ran cool.


then after detuning the car so he could drive it more with the family the damn thing took a **** an hour and a half from home. needless to say it has a stock water pump, stock pulleys and a belt driven fan on it now. all parts store things he can get if need be while out on the road.

This can be an issue as i've never seen electric pumps at a Autozone..

However, I have AAA and Hagerty so most times if any of my vehciles (or trailer) has an issue that requires aything extensive it went home on the hook.

true AAA is a life saver and we should all probably have it. the thing is if you just lose a wp or a belt then its an easy fix on the side of the road. changing from an electric wp to a stock set up is not an easy swap on the side of the road (unless you carry everything to do it in your trunk). plus depending how far AAA will tow ya it could cost a bundle. i have the higher 150 mile option which is a good distance for most of the time. but i like to take my cars further than that. and if i can fix it on the side of the road i would much rather do that and continue on my little trip then have to be towed home.

it really depends what you do with your car. i like to take mine on long cruises so with cooling and ignition things like that i rely on the K.I.S.S ( Keep It Simple Stupid) philosophy. i want to be ably to fix that stuff wherever i may be. belt driven fan and pump, mechanical fuel pump and stock or HEI style ignition system is how i roll.....
 
I will let him your comment and idea
he is the boss

he will decide if he still wanna go electric pump or no

thanks Bob
 
Some of the problems with Electric water pumps are people either use the cheapest one they can find or they use the standard flowing pump that is rated at 20-35 GPM on higher HP applications thats not enough. Call some of the Manufactures and talk to them, with the proper set up for a complete cooling system you shouldn't have any issues. I used Mezerie HD pumps (45GPM) on previous builds and currently am building a 416 engine and will be using the same pump on that build along with Dual electric fans and Aluminum Crossflow Radiator.

My current setup is a mech water pump, lol. I'll aways run a lectric fuel pump though. And they are available at autozone ;)

HEI!!?? Did this site just crash? :D
 
I've had a Mezerie 35 gpm on my car occasional use car for almost 5 years now and never had a cooling issue - actually I have an issue of it running too cool in cool weather. These pumps don't have a bypass on them so you can't run a T-stat unless you drill holes in it. I run an orifice plate in mine and it runs quite cool (typically 180-190 in hot weather, 160 in cool weather)..
 
Do they make one piece electric water pumps for Chrysler now. I have never really shopped for one but it seems like looking through catalogs all that I ever saw listed was the kit that uses a stock water pump with a toothed gear and a small electric motor.

Sure they do. Bolt right up to the block ports.
 
I thought the purpose for one is to eliminate parasitic drag on the engine, for drag racers. The electric pump takes power from the battery, so is kind of a mild form of cheating, like adding a hybrid drive. Longer term, the battery is recharged by the alternator, and loses make the over-all load higher, making the engine less efficient. I see where it would aid water flow at idle though. I wouldn't want the reliability issues.
 
One of the things I like about electric pumps is that you can run them when the engine is off. I always let mine run for several minutes after turning the engine off (along with the electric fan) to cool down a bit.
Today's brand name electric pumps last for thousands of hours of operation - many, many years, depending on how much you drive your car. Not much different than a mechanical pumps life expectancy.

From CSR.....

Information about your

Water Pump

Q: Do you recommend the use of CSR Water Pumps for street use?
A: Yes, a large percentage of pumps are sold to street users.

Q: What is the life expectancy of the electric motor?
A: The motor should be replaced at 3500 hours or 50,000 miles of everyday use
