Any one got a Craig Davies type water pump (115L/M) lying around that they want to get rid of and list! I dont want to pay the huge dollars they ask for them on Trade Me for new and dont realy want to order direct from the States in order to keep the support local. i want to help the main pump as I am moving my radiator to the back on my 350 Chevy Cruiser club truck.

ummmmmm 115 liter per minute lol you sure you got your facts right . i highly doubt . also there is usually a good reason as to why a radiator is up front and never in the back.

Hahah sorry guys, its a mud thing.facts are spot on.Bush trucks and comp truck mostly have the rads at the back to avoid damage to them in the front and getting blocked with mud from other trucks spining in front.Its been like this since Moses was a baby. Its so common to mount it at the back behind the seats/ on the rear roll bar where ever then connect a themo switch and electric fan thereby needing an additional electric pump to help the water flow of the longer distance and also hook a turbo timiner in line to let the water circulate for a few minutes after the enigne is off to elliminate heat soak and lower the temp for the next start up. 80/115 l/m is fine for this application.

I've been down the electric waterpump road before with a Holbay Cosworth motor, the pump you need is an impeller type, high volume / low pressure. The only solution is to bite the bullet and buy a purpose built Craig Davies; there's nothing else out there I could find that would do the job.

Yer can get some big capacity bilge pumps here on TM.

Why change!, the standard pump should do the job. Mid engine race cars do not need extra,or bigger pumps, and the water is moving from back to front whereas you are moving it from front to back. I do not see a problem.

i recently got a flyer from BNT which had electric water pumps for sale,not a bad price as i remember,they might be shite,but maybe worth a look

make one. use the motor from a 12v electric radiator fan, bolted to a dishwasing machine pump, thats what i have.

Nor does the pump in just about ALL cars. Your point is!

I think his (!) point is, he obviously has a good understanding of the application and what is required, and asked a pretty simple question yet instead of answering everyone wants to talk him out of it.
Or his point is something else and that's just my point ;)

The pumps are Davies Craig rather than Craig Davies BTW.
They are pretty good and saved me a few overheating episodes when stuck on the start/finish line under red-flag in the blazing sun

Pressure and velocity drop over distance. google it.

Sorry to say it does not work like this.

The standard pump will do the job, dont go too big in fact go smaller diameter hosing.

I've run run race cars with remote cooling systems, no additional waterpump and not had cooling issues. However the OP's sport of choice involves a motor having to work very hard in a low speed, stop / start enviroment; in that situation an electric pump would be very usefull.

my v12 has radiator in rear. Standard pump works well.I have a bypass electric pump set up that has never been used.

Correct and OP don't feel bad about buying from overseas think of the savings.

I stand corrected UJ, (dyslexia rules KO!). On the Cosworth I blanked off the mechanical pump and used an electric pump to get the coolant into the motor through the two frost plugs in the side of the engine block.With 32lbs boost running no1 with 20% toluene it was always a mission to keep cool; I ended up using a huge twin pass aluminium radiator that was originally intended to cool a blown big block. The electric pump was also great for managing the heat soak at the end of special stages, especially if the timing crews were running slowly and we had to queue.
