Davies Craig Water pump position ????

[shaunwil]

After 2 days of head scratching im still struggling working out where i can fit my electric water pump

Has anybody got any photos of one fitted where an fmic is fitted and the rad is stood up. Any photos would be greatly appricieated, but some above and below would be really helpful !

Cheers in advance,

Shaun

It\'ll fit nice in mine Shaun!

Which pump do you have large or small. I\'ve fitted the small from the bottom of the rad to the block. Tight squeeze.
Pip made the comment that it could be restrictive. He said he has seen them fitted in the heater matrix pipework.
Please let me know what you do as I\'m evaluating moving mine.

I\'ve got the 80l/min one, Its all the pipework where it wants to live. Im currently planning on putting it where the a/c pump lived and making some pipework up for it. I think the biggest headache is the rad is still sat on the sock brackets at the bottom and is extremely confined. I couldn\'t even squeeze through the anti roll bar and the rad without the front pipe on. Turned into a bit of a mare !

I can\'t see that you could fit it purely in the bottom pipe, the powersteering pipes and brake lines are completelly in the way, plus the dual oil cooler lines and i\'ve got a beefed up stay making thisgs worse !

Oh and kev i bet it would look nice in yours, you have loads more space in front of the engine than me :p

Which set up have you gone for? Are you still using the water pump housing to mount your Alt or are you going for the two pipe mounting and Alt in the Air con pump position?

I thought there is only one EWP? i thought the other was a helper pump?

[shaunwil]

Theres a 110/l min one as well thats bigger dimensions.

I\'\'ve got some blanking plates laser cut out of 2mm aluminium from work to remove the water pump completely and i\'ll get a shorter belt and use the original adjustment on the alternator. Im going to remove the studs and fit 100mm long bolts in their place. Much bigger job than i thought it would be. Still have to wire in the controller with its temp sensor and remove the thermostat.

Will be putting my underdrive pulley set from dragon in the for sale section once done !

yeh it gets out of hand quick, if you remember my white vert that had an EWP on, i went and put the two pipe plate on and moved the Alt to where the Air con pump should have been. they are good but i had agro with the sencers and fan switch..

[shaunwil]

I was wondering about that with me being able to get small stuff made at work but there are so many pipes that run off and the sensors i thought it was safer just to take just the pump off the front and leave the rest ! Will take some photos of progress tommorrow !

Well after having a 5 min conversation with pip he has solved it :god I\'ve ended up pulling the bottom of my rad 2in further away from the engine and it now fits in the bottom hose (using different piping). The only real headache is the pump is 35mm dia and the radiator hoses are 38mm so im having to squeeze a 35mm silicon hose onto a 38mm diameter. Using a 38mm 90deg on other end with an adapter in the kit, but that makes it 40mm  :2Rolleyes so another very tight fit.

Will take some photos of above and below when im finished. Plays stopped due to rain  :Tongue1

Exactly where mine is Shaun. I\'ve skimped on the controller and I\'ve retained the original pump. I use the first stage fan speed to switch on the pump.

If you remove the thermostat your car will take a long time to warm up. Especially if you are driving it. I don\'t know what your car is used for but if its used regularly you could be shortening its life. Mines a daily driver so I am compromised.

By the way. Some information from a fellow designer here, and also Keith Duckworth (RIP), put the plastic elbow supplied with the pump upstream of the pump and it will help resist cavitation. It breaks up the spiral flow of bubbles that can propagate and choke the pump.

The controller comes with its own temp sensor and alters the speed of the flow to try and maintain a constant temp. Would have thought this would be much better for the car. At the min over winter the thermstat hardly opens and that would be a worrying thing too ! At the minute the temps on water are not very good either 90-100! Hoping to get it to sit at a constant 75-80 degs all year round.

I\'ve got the elbow on the intake and the straight on the outlet. Its sat very low so hopefully it shouldn\'t be a major problem with cavitation. I hope thats the way you mean :p

At the minute the car is only used at weekends and trackdays / drag racing so it usually doenst do many short trips ! I\'m trying to prep it for a GT35r Turbo and make it as stable as possible.

Cheers for the info  :Thumbs-up

Can i leave the thermostat in and set the controller to 5 degs over the thermostat opening to get it to warm up quicker

Shaun

[shaunwil]

After some serious faffing about i ended up pulling the rad out another inch and got the pump fitting snuggly. Got some photos for anybody that doses the same job and struugles (like most jobs i do)

Still think it would fit better in mine Shaun! Let us know how you go with the water temps if any different.

ok, hopefully it should help keep it more constant. Some naff stuff with the controller and i still need to remove mechanical pump and finish off wiring !
