Intercooler water pump
Regarding the Bosch Intercooler water pump - is it the same model as used on the SL55? It seems the Bosch model is the biggest baddest they make.
Also what amp draw can the vehicle cope with ? There some bad *** pumps with very good flow rate that will need 7 amps though... I dont think the vehicle circuitry will cope with this amp draw...
for example

Reason I ask is if there is a mod for the SL55 ito cooling mod (i.e. 030) - it should be able to be adapted to the E55 quite easily no?
Anyone got details of the 030 cooling upgrade ... ? I am convinced we can adpat this for our E's...

Yeah seen pictures of the Johnson one - pretty handy looking but see its rated -10 to 100 deg c and has a plastic impeller housing - which is not so great. How hot does that coolant get ... ?

How about this puppy:

Electric coolant pumps for automotive applications will soon become mainstream - hopefully one of those will work for the E55. The idea is to have completely regulated flow based on coolant temperature.

All AMG kompressor cars use Bosch pump. 32s use a slightly smaller model, but they still fail in the same way.
We use Johnson pump that flows 90 LPH vs. 15 LPH for Bosch, it draws 8 amps and needs a relay to keep wiring harness safe.
Only about 15-20F above ambient. Pump picks up fluid after it has been cooled by the heat exchanger. It never sees hot fluid from the intercooler.

Thanks Vadim - How does the relay save the wiring harness ? Is it a voltage up convertor ... not sure how the relay helps...?

That EWP looks like the ticket - not only for the Intercooler but for the engine water circuit too.
Any thots on installing that unit using its regulated speed / flow system ? That seems an ideal solution for the intercooler ... and even for the motor cooling.

From maximum cooling stand point, pump running continuosly works a little better vs. pump coming on only when temperature reaches certain threshold. There is a lag between pump coming on, fluid reaching intercooler picking up heat, returning to heat exhanger and coming with cooled fluid.

Gotcha re relay - that makes sense... wired to alternator ? Fused I hope ... Is there not a +ve terminal source elsewhere in the engine bay ?
Is there programming available to turn the pump on earlier / lower temp than stock ? - or just to leave it on permanently with ignition ...

Of course, it is fused. There are no other easy accesible sources for 12V, except for fuse box by the windshield.
Unlike ignition/fuel maps which are fairly easy to find in the software, algorithm that turns pump on and off is a lot harder to locate. As far as I know no one found it yet.
