As someone who has only recently discovered the EWP, I occasionally do a fresh internet search to learn more.  Tonight a new article popped up which is really quite good on the installation and performance of the Craig Davies  EWP.  It can be viewed at:

Good point Jesse.  If I guess at 80% effeciency for the conversion
(WAG), it would only be 13.6 A.  I think it's just the alternator
efficiency though since I'm comparing to another EWP.

Bob: If only taking 200 W engine output, with alternator inefficiency and
ewp inefficiency, wonder what wattage would it be really using ?

 BMW___s system taking up a maximum of 200 W engine output as
opposed to the power uptake of a conventional water pump of up to 2 kW."

OK, so 200 W is about 17 amps.
