Is anyone running a electric water pump on a daily driver? What kind is it? and is there and benefit changing to the electric version? thanks.

not sure any eletric pumps are made for the street. i have a moroso on my car besides an expensive pump you need a 150 dollar pulley for the crank to drive the alternator.

i always thought elec. water pumps were strictly race only

Same here.

You're better off asking this on the camaroz28.com board. A bunch of folks run Meziere or CSI electric water pumps on their daily driven LT1s with much success. FWIW, both companies claim over 35 gpm flow and a 2500 hour motor life expectancy and can be run on the street with no problems.

From what I've been reading, I'd have no doubts it would cool just fine but reliability is my main concern. I'm thinking about running one myself but I'm still trying to get an idea of how reliable they really are before I do it.

i remember seeing some streetable ones in Summit cataloge.

yeah I am a little weary about, if electric pumps would hold up on the street.

Is there any power gain in going to a electric pump? I dont think it is worth it on a mild street/strip car.

thanks for the input. I here they work good on the LT1 but I had not heard anything about a 350 TPI motor.

thanks

The only purpose I could see for using one would be if you lived somewhere HOT and wanted to circulate coolant for a few minutes after the car was shut off. WIth an electric fan and electric water pump you could cool down pretty effeciently!

The http://www.meziere.com (said Mez-ear, not mez-e-air-e, like I used to think) site has more info. I sent a few emails back and forth to Don a couple years ago; interested in using the remote water pump for my 2.8 v6. (It's not similar to your v8 pumps, the whole back of the v6 pump is the gasket/sealing area!) Anyway, Don said that their pumps are extremely durable for the street, and they even offer rebuild kits for 'em.

Ah, here's the email, from March of '99 - I should clean out my email folders, eh? Here's a quote from Don Meziere:

Oh, and that November 12th he mentions... it was probably November 12th of '98, since that email was dated March 4, 1999.

The advantage of an electric pump is that you can install an SCR control and vary the speed of the pump based on engine heat, not engine RPM. You can cool the heads down quite a bit just before a run by manually cranking up the pump speed.

As for power gains or losses for a daily driver, all you're doing is transferring the load from the crankshaft directly to the alternator, which only introduced some more inefficiency. The advantage is for those short, peak-power runs you have an extra ½ HP at the cranks since the battery takes the load briefly. If that ½ HP is worth the cost and installation hassle, go for it.

thanks vader.

That was the answer I was looking for. My friend has a 70 nova, and was suggesting that I swich to a electric water pump. His car is strickly race, it hauled to the track. I dont think it is worth the time or the money for such little gain on a street/strip car.

I was just needing proof.

Thanks again.

Electric water pumps are not just for the strip anymore. Everyone talks about the Meziere 35gpm pump which works AWESOME in LT1 street vehicles. Well, Meziere also makes a 55gpm electric pump with a heavy duty motor. Yea, thats right ... 55gpm. I just bought one ...

What advantages do you think you will get with it? Do you have it installed?

Any helpful info you could share TRAXION? Did i see a pic of when you had a CSI pump? If so, how difficult was it to mount the accessory brackets? I also saw brackets that look custom on your set up! Are they? I am having trouble mounting things now without the stock pump and using the CSI pump. Any ideas or suggestions, from anyone? Thanks for your time-Bryan

Bryan,

I do have a suggestion but you are NOT going to like it. Meziere now offers a BOLT-IN electric water pump for serpentine TPI applications. It comes with an idler pulley so that you can route your belt around it just like stock. It's an awesome idea. But, be prepared to pay for this setup .... it's like $425!!

I have this same pump but WITHOUT the idler pulley. I have a fully custom setup so I really can't be of help too much. However - you could always just reroute your serpentine belt? Crank to PS to Alt to tensioner to AC to smog to crank. I haven't tried that routing but it might work ... just depends if the belt has enough footprint on the crank pulley.

Tim

Thanks a lot, You da man! Seriously though, i came across another old post and found that pump. I believe someone with a Trans Am has it, forgot his name. I believe the part # is WP3215 if i wrote it down correctly. I will have to call them on Monday and see what they have to say. Yeah, i figured your brackets were custom, really have not seen any like that around! I just looked on your picture directory and figured they were custom. On your site i don't recall you naming them. Anyways, thanks for your help. I am probally going to need some more info on other things but i'll just PM you i guess, if you have the time though, no big deal. It just looks like you have a lot more experience with this setup than most who are willing to share the info. Thanks a lot for your time again. Later-Bryan

I think you would gain quite a bit of power from an electric water pump, since you could turn it off while you raced. So you would have no draw on the alternator. I think I am just going to ditch the serpentine system and just run the crank, alt and powersteering.

That was my intention, not nec. for "more" power" though. I was planning on running a relay for the pump and the fan in my car. This way in the staging lanes i could always turn them on to cool off and shut them down for the track. Not so much for the pump but definately for the fan! The car is not even a daily driver, just my toy/money pit/baby. What my real concern is though, using the CSI pump, you can not mount the accessory brackets anywhere! As far as i can tell anyway. This was my question. How to properly hook it up and my accessories too? I will have to either go with that Meziere pump or go with a regular old aluminum pump, either Stewarts or Edelbrocks. We'll see, but i doubt i'll get this pump to work with my current set up, unless someone has any other ideas. Thanks edit: oh yeah, there was someone who posted dyno results with an electric pump. It was in an old post i found on this topic. I believe it was 11hp. Not bad but every bit counts!
