What small block Mopar electric water pump to use?

While at Monster Mopar I ran three classes, two were back to back, and I need to be able to do some quick cooling down.

I tried the belt driven electric motor on the water pump (Moroso) but it lasted 2 passes before the motor fried on it (last year).

What do you guys recommend?

Does it have to be electric? Running like that I'd rather have a high flow water pump, overdriven turned by a belt.

Husband said he wants electric.

Damn. If my wife listened like that, I'd have an alcohol funny car!


Well, in that case, I've used the Miezere (sp) pump. I can't remember the GPM but it was the biggest I could find.

Messier is a top not product with great service. I have had one for about 18 years and it has needed service once.

Merziere is top notch, but if you're looking to save a few bucks I've had good luck with Proform. That and a Champion 2 core radiator keep my iron headed 408 under 170 degrees on the street and plenty cool at the track.

Have Meziere on both mills.... and I'd do it again

running lots of classes? go BIG on the radiator. I also have my water pump and electric fans wired into and extension cord plug. Hook it up to a deep cycle battery while in the pits. That was I can cool all I want and not beat up on my primary battery.

I would recommend this with a good electric fan. This will help keep it simple.. bolt up and go.. https://m.summitracing.com/parts/mor-635...4saAtPBEALw_wcB

I have that one and like it.
Key thing is between round cooldown not running down your battery.
I like the idea Jbody had in his post, using a spare battery.

How tight did you have the belt on the Moroso? Tight belt will kill those little motors.

I like my Meziere pump, trouble free for years.

To save a little room on the front of my motor I did a little welding and milled off the water pump recess. That way I did not need to use a block off plate. Saved about 3/4" and a little weight

I've used the moroso billet electric one for about 3 years now. No problems ever.

Meziere is a great company with excellent customer service. I would go that way with a good electric fan and shroud if possible.

Whatever electric pump you use, make sure you have VERY GOOD grounds.

Meziere

lol! he's my crew chief, so I have to listen to him. Plus he's my favorite person in the world.

Probably too tight! Good to know, thanks!

we'll do that.

Thanks guys!

I have been running a ProForm on my small block for around 5 years on the street and track. It cools down quick between rounds and keeps it cool on the street.

I run the meziere that mounts on radiator and I love it!

Kath.. I've been running the Merziere pump for
about
15 years.. I have 2 of them.. very good product
EDIT
Also.. they make 3 versions of the electric
pump.. a 35,42 and a 55 gal per minute.. the 35
is all you need for racing but for the street
you might want to step up in volume.. I'm thinking
about changing the motor on my smaller one to put
in a 55GPM in my hot rod.. I havent had any issue
with the smaller one but it is a option(and its
just a motor change

Meziere I've had mine for over 20 years.

Thanks Mike...and Guitar....and everyone else! Much appreciated!

Dustedu please share the water pump set up.

Probably one something like this. My small tire car came with one mounted on the frame and I bought two of Andy's water manifolds.

Meziere is the way to go. One other thought why not get a cooling station like the stock/super stock guys use? It takes 5 minutes to drop engine temp below 100 degrees. If you are doing that much hot lapping what about trans temps?

My Friend makes and sells these.

Use a 8 blade pump mech pump Air cool between round using a electric rad fan The electric water pumps are for all out race car with between round charging.
Is this car a drag only car? .

I've never had any issues with a electric water
pump.. look at production cars.. they run electric..
if they have the flow(most do) there wont be any issue

Yes it is, for now.

I bought a CSR pump back in 2007 for my Dakota and ran it as a daily driver till 2009, last year the motor finally died. Contacted CSR and bought a new motor for it, swapped it out and works great when my engine is in the truck, lol.

Probably more like this, I would like to move to one of these as it would open up fan options for me.

Two outlets, I machined cover flat and tapped the engine plate for two 3/4" holes in line win he holes in cover

Dusting off this thread, as I am curious: Has anyone used this pump and figured out a way to hook up heater hoses? I have two threaded ports on the Indy intake; one location can be one heater hose but the other one one will source engine temp.

Just wondering out loud if it's possible.

Thanks!

Just a guess, but if you drill and tap that anywhere on the flat portion near the block water inlets I imagine it would divert some water to the heater core, but I don't know if it would be enough or not.

See my poor illustration with the blue area being the area to open up for a fitting.

Thanks! I was thinking he same, but was hoping someone was successful before I fire up the drill press.

I guess a concern would be that the heater core ends up the path of least resistance and that side of the engine doesn't get as much flow as the other side. I don't drive mine much in the winter so when I do I just plan on freezing lol.

Meziere housing with block off plate that I made Stewart remote pump LOVE IT

You need to remember that for water to flow through the heater one side is on the inlet side (bottom hose) of the radiator water pump inlet(suction) and the other side, intake manifold fitting is on the outlet side( hot water to the heater)
