Electric Water Pump - Anyone bothering with a controller ?
Posted By : Richard King, 20-Jan-2004, 03:25pm
Just run it fast until the engine cools down? I think the less things to twiddle with when I'm driving the better, I'd only forget to turn it up one
day and wreck my engine.
That said I don't use an electric waterpump (yet).

thats what I mean... definitely no twiddling on the track....
but run it slow while moving to the assembly area etc etc... so my engine at least gets a bit of a chance to warm up before the off...
and have it on full on the track...
see, but thats the quandry... do I need one of those controllers ?
is full blast gonna freeze me engine ?

I ran with a controller for most of last year, but I am not using it this year. So if you want one, I have a spare - any offers?
I found it tended to stay on in any case as the lowest setting is for 80 degrees C. I fitted a resistor (supplied free from Davis Craig) to bring it down top 70 degrees.
Don't worry about getting the engine up to temperature - you get plenty of time. Infact, without a fan I'm stuggling to keep the temp down until the green lights.
As for the on/off debate - you can have a seperate switch or simply link it to the ignition. Pro's and Cons? Well if you have the switch you can turn it off, but then again you can forget to turn it back on. Also, The switch should be 'out of the way', John Thomason once turned his off mid race during a particulary violent corner and ran nearly the whole race without any pump
I have an on-off switch and idiot light

Nigel, I presume the idiot light has nothing to do with the water pump...how does it know if you are an idiot or do you just turn it on prior to each crash?-

thats a bit harsh surely...
anyway...
My thoughts exactly Mr Vowell..
just worried that someone would tell me I definately need the controller..
No need for a controller then, but I like the idea of being able to control the thing in some way, rather than leave it to its own devices !
Especially as you have to take out your thermostat.
Plus I like as many things to check as possible..., it gives you something to do on the straights.
I don't *think* I'm going to have any cooling probs though..I should mention about the fan on this car I bought...
I think Martyn had some strange plan about a fan propelled car.. I turned it on in the garage earlier and I thought the car was going to take off..
Probably won't fit the water pump till after my first test day anyway...
but you know how it is... there's little to do on the car,.. so I'm considering the few bits I do have to do carefully !

An on/off switch gets my vote with a light showing its on that you get in the habit of looking at to check. Save cash and weight.
Just have it turned off to warm the engine with no water flow, just like having ta closed thermostat really.
You only blow one head gasket then never forget to turn it on again
Put the switch far from the gear lever or steering wheel to save knocking it off by accident.
If I fitted true idiot lights it would be like blackpool illuminations every race day!
