Electric water pump
Turbo Mini Forums

Right , i must of looked through 5 differend threads on water pumps and flow rates and im completely confused.

Ive only had the mini running a few times (probs with mj , fueling etc) but the twat wont stay cold. Ive got a davis craig water pump and after messing on sat ive managed to brake it.

Got the car running and after 5mins it spewed its water out (id left the rad cap off) then decided to put the cap on and see if that would help but it didnt it split the water pump.

I dont want to get into flow rates etc id just like to no what people are using and what rad set up you have. When i got mine i didnt do any reading up i just presumed that it flowed water and was made for cars job done, obviously not

Im running a metro set up, front mounted rad with expansion tank and thermostat blanking sleve.

Ive briefly spoken to si p today and the thaught is thats its been flowing too much water and could of quite easyly got air locked and bust, id did take the top hose off the other week and omg it fired it out of the top, so it seams to kinda make sence.

Any help guys.

Rick

ps, i think in the meantime in going to cobble together a standard pump just to check everything else

Im using a Meziere pump (flow 80l/min or something like that) with chiquecento rad. I don't think these pump like restrictions so to be on the safe side I used a shuttle type thermostat. Been fine for 2 years now, and to be honest sometimes struggle to get it up to temp on cold days. lol

Im using the same pump and my temps are usually around 70deg, sometimes cooler

Ive got a massive rad and a crossflow of water though

what were the temps like with the side rad and no fan Nic?

a lot higher!!

90+

Interesting...

did you find you had to turn the fan on to keep it cool on the motorway at all?

It used to run all the time tbh

Do you both just run the pump or is there a contoler with them

Rick

Cheers Nic,

thats what i'm pretty much seeing, looks like I better have a cooling system rethink.

Sorry for the Hijack Rick!

we're not running a controller

Ive often thought about putting a variable resistor in though so i can keep it warm when following slow traffic

No worries joe, it just nice to see whats peolpes thaughts are in reality rather than practice.

Ive just put mine on a switch so the theory was fire the car up then two mins later flick the pump on and i could also leve it on after ive turned the engine off.

Rick.

Nic, matty , got a link to them , there seams to be loads in the states

Rick

thats were ours came from, jegs.com

Point taken tom, it did cross my mind , il have to put it so i can overide it so it can be left on when the engine is off.

Mike its a map from james' site

I have mine on a switch, it just becomes habit to switch it on now. And it somes in handy to cool the turbo/engine down after you switch it off to avoid heat soak etc.

Mine ran about 20 degrees hotter when my ignition timing was retarded too much.

I have a handy button that I press and it turns on the fan and pump for 10mins, optional on shutdown

Sorry to thread hijack, but does anybody know if this pump would be suitable?

I believe the flow rate is about 20liters/min.

Yes i moved to the darkside

Instagram @jdm_brett

Going on from this does flow rate really effect it that much, is the ideal flow rate 80litres/min and what will happen if i fit lets just say a 120litres/min what will happen? will it not flow as well due to the coolant being flown to fast ?

i second that comment, i was going to buy the 115litres a min davies craig (alloy) pump WITH the controller?
