electric water pump?

[JoeliusZ28]

anyone running one of these?

Im thinking about picking one up, supposedly they can free up 10rwhp. ive heard cars can run both cooler and hotter after making the switch. is there need for concern about them failing? I would imagine it wouldnt be very good if one quit on you, anyone got any experience with that?

In a majority of our LT1/LT4 builds we use the CSI electric water pump, and we have jet to have any problems. It frees up some power, and in our cases allows the customer to run the less expensive Cloyes timing set.

I ALMOST put one of these on my car ( Meziere) . The same shop that did my cam work talked me out of it saying that they had problems with the aluminum warping and therefore leaking so I never had it done BUT I was talking with one of my buddy Dave ( who happens to be a mechanic and fellow horsepower nut) and he said the shop was probably B.S'ing me because they didnt want to put it on because the shop was so busy. That shop (Generations Plus)was a nightmare for me they promised me my car back in 3 weeks but they had it for 5 months! And they closed down shortly after ( Apparently I wasnt the only one getting screwed and they had like 11 lawsuit against them ). So I tend to think my buddy was right but I thought I should mention it.

e-water pumps arent supposed to leak from what ive read. my only concern is the pump failing... cause i could see that causing some issues real quick. am i paranoid or not?

[01SunsetWS6]

no i dont think your paranoid, it definatly something to think about. A good pump should not fail but with all electronics there is a possibilityof failure. i would make sure to have a good water temp guage and put it somewhere it is easily monitored. there are also switches that engineers use that hook into the comp. i dont know where to get them but they use a pyrometer and would shut the engine down if it reaches a certain temp like lets say 220 so they would not fry the motor.

the thing that scares me about the e-pumps is that they are only rated to last x-thousand hours. im pretty confident in my factory temp guage, it seems to read accurately.

Why risk it for a few HP? If you were running a drag car, then I would use one, but for a daily driver...not me.

Regular water pumps will also wear out. I'd just rig up a temp LED or something and run it, if she starts getting hot the light would get in your face and you'd be able to shut it down in time.

[SlipStreamZ28]

Well thats just the thing,its not a daily driver. More of a summer car from what hes told me. But I agree unless its a drag car its kinda a waste of money
One nice thing though is their a little smaller so it unclutters your front end a bit. It might even be small enough that you could pull the opti-spark off without removing the water pump which would be nice but im only guessing so dont quote me on that.

In all honesty joel I doubt you'll see 10rwhp out of a electric water pump mostly because our pumps are cam driven not belt.
electric water pump and a under drive kit yeah maybe but not just the pump itself. Not to mention the pump is gonna cost about $170 plus another $60 for the install stuff plus labor (unless you do it yourself) . Meiziere does make a heavy duty model for our cars if you really want to do it though, although I dont know that it will last any longer.

[JoeliusZ28]

yea ive seen dynos that have shown 9rwhp from the switch. I agree that seems like alot, but thats a good gain for $160.

and yea the car is not a daily driver... never will be again. Ive had it over 3 years now and have only put 11,800 on it in that time.

wow im surprized, usualy companies really inflate the horsepower gains.

[c0ncEpT]

The word on the street is that they are only good for 30K miles.

What he said...there's better ways to gain 10hp...IMHO...

if my car were a DD i would never consider it. i wouldve never done longtubes either in that case. but what i like about this mod is that its 5-10rwhp... freed up. It isnt adding any horsepower, or putting any more stress on anything, its simply allowing the engine to send its power where it belongs. therefore this should also warrant a gas mileage increase.

Im pretty sure this is something im gonna do. I will probably replace the pump after 25k just to be safe. (25k on my car should be about 7-8 years of use... thats not bad).

one last question though... do e-waterpumps continue to run after you shut the car engine off and leave the ignition on? If so this is definitely something i want to do to help my car stay cool at the track.

You can wire it however you want.
