Electric Water Pump
Hey, though I'd ask if anyone has the Davis Craig EWP on their 4bie?
I sent them an email asking if it'll be ok during a water crossing and they replied that it can run for an hour underwater! They also said it'll be a good idea to have an overide switch to turn it off during water crossings.
Anyway, just wanted to get your opinions on the EWP cause I've been thinking about one.

I've heard only good things about their fans, but very mixed reviews (to say the least) about their water pumps... or indeed about any electric water pumps, when compared to stock mechanical ones.
The word is that they just don't do the job.
But, this is hearsay, not personal experience. What do you want it for exactly? To boost the mechanical one or to replace it?

This is not legal advice.
If u go the controller it will slowly pump when the engine is at operating temp and gets faster as the water heats up. I had to get a higher pressure cap for my radiator because when the pump went flat out it would unseat the cap and pump water into the overflow bottle, they do pump a fair bit of water.

Actually they are in use in some cars from the Factory but you want a Bo$ch one.tweak'e wrote:afaik the biggest problem is simply reliabilty. an electric motor is simply not as reliable as a mechanical pump. for comp or 4x4 only use an electric is proberly ok but its not really reliable enough for street use.

A workmate tried a Craig Davies electric pump as well as their thermo fans to try and extract more HP from his worked V8 HQ.
He started having overheating problems straight away and the cause was found to be the pump was cavitating the coolant.

Personal experiance about 4 years ago
I purchased one for my hilux running a 253 it failed the seal gave out after 3 months I rang them & they told me there were issues with the seals it was replaced it also failed it was replaced this one is still sitting on my bench at home as the 253 was removed not long after & I have no idea if the seal problem was fixed they did tell me they were working on it.
They did however provide enough water flow.

Sudso, what do you mean by cavitating the coolant? Is that not flowing in the one direction?
Longlux, I've 'heard' of a few failure stories with the EWP's of a few years ago. Do you know what series you had as I believe their latest one is the 3rd generation. Would like to think they've sorted out the problems of the earlier models......... BTW, the one I'm looking at is the 110 liter per minute one. It's also got a cooling fan attached.

Not sure which one this is it.
It has been sitting in the shed gathering dust.
I also got a controller for it.

I think it would work alright with the mechanical pump still attached, but I would not get rid of the mechanical pump unless it was just for short comp runs, maybe.
