Water Pump... Mechanical or Electrical?
Can't use the OEM one on the RS4 engine, but there are spare drive pulley's I can use, or I can go electric... any one
'better' than the other?

ive looked in to that my self as a comon fault with the rover V8 that iam going to put in is that there run hot
iam thinking the electrical pump my be the way to go as rigged to some type off turbo timer it could be set to run on after the engine has been turned
off alowing water to keep going round the engine un till it had cooled down preventing any heat sincking your damge

if you fit an electrical pump couldn't it alsa be wired through the thermostat like radiator fans on newer cars. You often hear these running on
after stopping
Life is like a bowl of fruit, funny how all the weird looking ones are left alone

I'd have thought an electric pump is less efficient than a mechanical one (mechanical -> electrical -> mechanical vs mechanical ->
mechanical).
Also you'd need to think about failure modes - what happens if the pump fails? If the battery is low etc. Also think carefully about anything
that runs on after the engine is switched off, as not only can it drain the battery there is also safety to take into account.
Sounds like a cool idea though!

Lots of forum chat about leccy pumps HERE. The IMOC one is interesting, seems that mounting
position and angle is critical

all good point but bear in mind an electrical pump with controller would run as needed as opposed to be running all the time so may use up less
power.
regarding failure, you would need so means of monitoring the motor as well as temperature and have some indicator or engine cut off device.
ping Razman - he had one fitted and I think had good experiences with it.
