Hi.

Im wondering where you guys decide to use an electric water pump, or if its just to have it running while in the pits with the engine off, to cool things down with small radiators/limited airflow.

I have a dsm, and Im converting to auto. Im just concerned with blowing a rad hose due to too much pressure from the RPM's with the auto. I've seen it happen.

I could just weld -16 fittings to my inlets/outlets and use braided lines, but with an electric pump it would keep the pressure down, and I do like the idea of being able to run it in the pits.

My tbelt dosen't run my waterpump, so it would be as easy as putting a blockoff plate where my waterpump is, and welding a -16 bung onto it, and plumibing in a meziere pump.

My second question is, which pump is the most common to use? As well as line size, is -12 and a 55gpm pump enough?

Thanks.

 

I broke my water pump last year and some how some way, didn't damage anything. I got real lucky, but I'd like to run one next season if the street classes permit it. In the pits, we just run fans and it's more then enough to cool our cars between runs.

On my buddy's evo, he runs a hard blocked 4g63 motor and hes and electric pump to aid with cooling the head since there's no water running through the block.

 

do you get more power to the weels with an electric waterpump??? on a b serie??i think so because your belt don't need to drive it. but i'm not sure

 

you definitely free up some power...but its negligible.

I think the reasons to do an electric water pump are:
- Space
- Simplicity (no T-Stat needed)
- Frees up HP by eliminating the drive belt (some application)
- Cool in between rounds better

I'm sure there are more...im having a rough morning

 

Space? As in you have space to waste under the hood and want to put a pump there? I'm not sure how you'd be saving any space putting in that pump.. Well, unless the pump was on a shelf and you needed the space for something better.

 

haha thats funny. i actually have one on the shelf that ive tried about 40 times to put under my hood, but its heavy and no matter where you put it its ugly. i think im just not going to use it because its ugly hahaha

 

I figured it wasn't worth it for me. I did weld some -16s to the rad/engine and did the hoses outa stainless braided. Figured it would help with reliability.

 

I guess you're thinking B Series and I'm thinking K? I dunno...freed up space in my application and made things simpler.

 

for those looking to get that extra 2-3 hp and allows u to cool motor without having motor on which helps. for a k-series cleans up that side of the motor.

 

i dont know, my car cools down no problem without any fans sitting on top of the engine blowing on it.

 

The time you'll want an electric water pump would be:

- shorten cool down times greatly between runs

- spinning the engine at a really high RPM, so it improves reliability in a fashion which the stock water pump isn't going to crap out; or when it does, it won't cause carnage with your timing belt and bring your whole motor with it

- Prevent heatsoak on the motor so the head won't overheat. But this doesn't really apply to B-series, but more so for bigger engines like a VW VR6, or an iron block 6-cyl's, etc..

- Improve cooling on street cars. The stock water pump is under-driven compared to most other makes and models of engines. You'll notice our B-series like to get hot when sitting at idle, but a little bump in revs will help bring the temps down. An electric water pump will help in that regards.

That's all I can think of

 

How reliable are these electric water pumps?

 

I'm looking for one if someone's gone one FS

 

very,, ive had mines for 5 years now and did everything with it from long road trips to track rentals with it and no probs

 

If you guys keep the theromostat in the car how does it really cool down? Once the thermo closes the water stops from going past that point...Just wondering

 

they just remove them...hell i run mine with stock pump without a thermostat and it never gets over 190 unless its 90+ out then it might read 200 at the top.

 

I have a Meziere kit minus the pump delete plate/wheel. Golden Eagle sells them seperatley though. PM me if you're interested.

 

You're suppose to drill a bypass hole in the thermostat when installing an EWP. At least that is what Meziere recommends....

 

I could have sworn i saw tony post somewhere too run the thermo.. Guess i was wrong.

this is what ive done numerous times and it works perfect or you could get a restrictor jegs/summit sell them

 

why don't you ask dsm guy's? I'm sure they'll know, better for dsm set ups?
