I always loved the complete failure to understand how the heat flows
in the waterboxer evidenced by good ol' TK's "scoop cooler".
Transmission fluid is kept at the coolant temperature by the heat
exchanger. When he says "the temp needle rides lower" with the scoop,
he's basically saying he's using a drag-inducing scoop to lower the
coolant temp (via the ATF heat exchanger) below the thermostat temp.
He could achieve the same effect by using a lower-temperature
thermostat (since ATF temp follows coolant temp) and letting the
radiator do the work! An oil cooler scoop is the same sort of thing.

Wow. I like that idea. Might take a little detective work to find
hoses that fit, but it looks like it might do the trick. The TDI guys
seem to think highly of it, with their chipped n' tweaked heat-blaster
engines.

I'm personally leaning towards a thermostatic sandwich plate and air
cooler like TenCentLife did, but only because it seems a little more
fun to install...
