electric WP, CSR vs Meziere

[kwd1]

Hi all,
getting ready to repalce my leaking (37k) water pump with an electric. I've always heard people talk about the Meziere pump. At Summit Racing they have another kind called CSR. It's rated at a lower gallons per hour and hence current draw. I suppose this frees up power for the wheels.

Does anyone have the CSR or know anything pro or con about it?
thanks
Ken

The C4 Corvettes use a short water pump, so you have to take that into account. Also with the serpentine belt system you would have to do something about the pulley on the water pump (most electrics dont have a pulley)

I bought a Meziere electric water pump a while back, have yet to install it. The model I got has a serpentine idler pulley. I got it from Summit the model is MEZ-WP321B, and the flow rate is 55 GPM.

Hope this helps.

He has an LTX motor in his 96. The water pump on the LTs is shaft driven so there are no belt routing issues.

I have heard good things about the Meziere heavy duty water pump's reliability.

Have had a Meziere on my 96' for two seasons now and couldn't be happier. Easy install and no problems yet. I think the CSR wasn't out at the time I bought the Meziere, not sure the flow rate would be enough for the C4 as hot as these babies run.

Why are you converting to an electric pump? Is this a street car or a race only car? Just curious.

Have a great day,

It's my daily driver when the roads are dry. Since I have to fix my water pump, now would be the time to go electric.

There is a thread in the LT4 section about the CSR. From what I remember, they said the CSR doesn't work on the LT4, and they returned it to buy a Meziere. I can't fathom why it won't work still... I want to do the conversion as well, and am waiting for someone to tell me if the CSR will fit or not.

 

[MBDiagMan]

I still don't understand the purpose for putting an electric water pump on a street car. Can you elaborate?

Have a great day,

Yeah, that is a pretty good argument against the CSR. when I looked at the CSR link above, it only says LT1, not LT4!



MBDiag, the purpose is to have more power; is there a good reason not to?
If so, can you elaborate, thanks

LTX water pumped as shaft drive and on the early LT1s when the water pump fails it takes out the opti. In addition if you use an electric pump with a LTX you can use a regular SBC timing chain, (they are hundreds of $$ cheaper than the LTX chain), besides the 7-10 RWHP boost you get from the electric.

In summary:
You can get some extra HP, the price of the SBC chain makes the Electric water pump cheaper to install than factory if you are performing a cam upgrade, the pump won't puke on the OPTI and you get some HP to boot. WIN WIN

On top of what was stated above:


It also runs more efficiently... since it always runs at 'optimum' speed, the car is always getting the right flow through the engine...

One last benefit is the ability to keep it on with the engine off. This allows you to cool the engine down if you need to (like at the track).

 

[MBDiagMan]

Thanks for the explanation. I'm glad to hear that there are some good, practical reasons for using an electric pump.

I'm not sure that I buy the HP claims, but the other reasons would be enough for me.

Thanks again, one learns something new every day.

Have a great day,

:duh Man I am normally better than that. Somehow I totally missed the fact that it was an LT4. My bad.

Vettelt193 gave most of the reasons I got mine. That and whatever amount of HP boost I could get. A couple here a couple there sooner or later they start to add up.

Is the LTX motor reverse water flow ?

the LT1-4s cool the heads first while the Old small block cooled the block first

Yes,
