smckeown 1 Posted October 14, 2006 Continuing the theme on extracting more power, has any of the track/race folk replaced the OE water pump in favour for an electric version ? cheers sean Share this post Link to post Share on other sites
jonD6B 0 Posted October 14, 2006 Not on a 205 but have helped a friend do his on a 200 SX. Can you make your own if you know the flow rate? Share this post Link to post Share on other sites
cyman 1 1 Cars Posted October 14, 2006 yep, i fitted one to my 205 with the electronic controller, ( craig davis ) works great, no problems so far. Share this post Link to post Share on other sites
Anthony 1,000 Posted October 16, 2006 Give James-R a shout - he's run them in the past with good results, and is currently sorting out fitting one to his forthcoming GTi-6 lump Share this post Link to post Share on other sites
Miles 331 1 Cars Posted October 16, 2006 I've got one on my shelf for my GTi6 engine when I build it, Was going to use it on my 309 but plans change as always. I know people have used these with good results and with the added bonus of keeping the pump on when you turn the engine off. Share this post Link to post Share on other sites
petert 554 Posted October 17, 2006 I guess you'd need to remove the pump vanes, or fit a shorter cam belt? Share this post Link to post Share on other sites
smckeown 1 Posted October 17, 2006 (edited) I guess you'd need to remove the pump vanes, or fit a shorter cam belt? Yes that's what i've read, ideally i;d have through you'd want to do both to get the full benefit. To the people who have or are planning to do this, are you running with the external regulator, or run it on full power always ?

crogthomas 0 Posted October 17, 2006 One advantage of an electric water pump is that you can match its use to engine temperature. Therefore you can restrict the power it consumes (via the alternator) to only what is necessary, meaning more power is available to drive the wheels. By running the pump on full power you are consumeing the full amount of power all of the time. Pointless. Running it with the electronic controller is the most sensible way forward. It does cost more though. Same principal behind running a electric radiator fan versus a crank driven one. Share this post Link to post Share on other sites
cyman 1 1 Cars Posted October 21, 2006 yep, i'm running mine with the electronic controller. i think iv'e got a spare one floating around if someone needs one. also, i did look at bypassing the water pump, but finding a shorter belt at the right spec was a problem. so i removed the impellers. i put the thermocouple in the thermo housing.

Guest BrainFluid Posted October 21, 2006 Is this not half a dozen of one compared to six of the other? Wherever your drawing the energy to power the pumping of the water its still going to be comming from the cam belt? Hmmm, unless that is if your going to switch the alternator off entirely every other lap or so and just run off what juice you have in your battery for sparks and electric water pumping. If thats the case then it could be bloody handy on the track... Share this post Link to post Share on other sites
cyman 1 1 Cars Posted October 21, 2006 i'm not sure of the current draw of the pump flat out, but i would think it would be more efficient than the standard setup. as for the ( battery for the pump ) it's the xtra weight, i know how you track boys hate this.
