seperate s/c cooling from engine cooling

Having the A/C will also rob power, not so good either. By having coolant reservoir of about 2 gallons, you will have enough cold coolant for at least 15 second full throttle (pending pump/reservoir), then the system will heat up if no radiator helps. So as long as you are not running on the autobahn or on a track the periods between wots could be just enough to have the system cold enough again for the next wot.

That's what the KC people say to do on their website. AC systems these days don't rob as much power as they used to. It's a trade off, but there must be some kind of logic for it.

Ok, we are ready with the unit, here it is:

Glad that something existed already, so I have ordered one, and will play with it to see what is possible.

Did you ever actually set this up as an intercooler fan controller?
If so, how did it work out?

Not yet, just to many things going on for the moment and there is no need for it, however it is on the list as a fine tune project.
I have already workout out on paper how I need to connect it (would only need to find the paper again ;-)), and iirc I with 1 or 2 extra relays it will be able to use the fast speed fan option (so sotck fans instead of extra ones). I feel confident it will work, but it will take at least until summer before I know it will...
It will not work on an Stype though, only for the XKR, but I see you could use it on yours ;-)

Please note:
The intercooler circuit works independently from the engine coolant circuit
There is only a small tube connecting the intercooler circuit with the engine coolant circuit AFTER the radiator, and the air bleed tube on top of the intercooler radiator to the coolant box.
....
As mentioned there is NO flow between the two circuits other than pressure equalization and some contamination, so all I can imagine is only some drops flowing over

During a cooling system flush, it was found that:
-- the drained coolant mix from the engine circuit was RED (dexcool)
-- it was replaced with water and run for several days
-- during the final flush, the same circuit drained CLEAR
-- the drained coolant mix from the intercooler circuit was GREEN
The coolant had not been touched by the current owner. So, it had the opportunity to mix for several thousand mile. And did not mix. The circuits each retained the unique color of the coolant in each of them.
Not really desirable in the particular car. But, it ought to be pretty good proof of your assertion.
