would it be enough to pump the water to a heat exchanger at the rear facia?
There would be no problem running the heat exchanger in the rear of the car as far as water pressure is concerned. Well almost none. I tested the system with rear mount and front mount and the front mount system has a much higher flow speed than the rear mount with the same tubing. Just friction. That increased velocity has some fringe benefits like being more efficient and quicker cooling response.
The other problem with the rear mount heat exchanger is airflow. The air coming under the car is already forced into a directional slipstream by the front air dam as it tries to force most of the air up into the radiator area. The remaining airflow under the car is small and would tend to continue in a straight line, not turn upwards and flow out the cutout of the rear facia. Maybe if you put an airdam in the back right under it, it would help.
I have some doubts as to the wisdom of that move though if you like to drive at high speed.
There is one thing about all this intercooler stuff that is disturbing me.
How come I am the only one to do any testing on this stuff? Search for it. The front mount resevoir, pump and heat exchanger has proven to be markedly more efficient in my testing than the rear mount stuff. The reasons I stated above plus the ones you'll find in old posts will help explain it.
