so... i aint got room for the standard water pump (even the shorter P6 one) on the V8 (depth 13cm) and you can get an electric jobbie thats 7cm deep - bang and on.
how the hell do they mount? do i have to blank off the pump and run it remotely or is there a version that actually fits whre its meant to? anyone ?? ??

As far as I know you can mount them anywhere but I don't think there are any that fit where the old ones are so that will need blanking off. Not sure if you are supposed to run an idler pulley where the old one was or if you just run a shorter belt.

A word of warning about electric pumps. We did some proper analysis on a very well known Electric water pump to check the claims. This included CFD Flow analysis and dyno testing a fully instrumented motor. It was correctly sized for the test engine according to their advice. End result was some seriously hot cylinder head temps (in the casting not just the water) with localised boiling, cavitation and erosion of the casting due to localised boiling  On the dyno initially there was a tiny gain, but as soon as it got up to operating temp the power started to drop off markedly...... the pump did not shift enough water to cool effectively. it set up a certain "Flow" through the system, but not enough for effective heat transfer from the castings to coolant. Just thought you should know....... because you wouldnt until you end up with a porous casting some time later  You would be better off remote mounting a water pump from something else and belt driving it HTH Dom |

I haven't really had much to do with electric water pumps, but in my opinion a belt-driven one is preferable where possible - the size of the electric motor you'd need would probably negate any power gains you'd get by taking out the belt-driven one. I realize that it's a space issue rather than a power thing in your case Marina_Coupe  Remote belt-driven pump sounds a good idea - best of both worlds really. Is there any way you could re-locate the rad (move it forwards maybe?) or even shift the whole powertrain backwards?! Bit drastic just to get clearance for the water pump but it may be better in the long run?! |
