If you hit it full throttle on the street then drove around for a couple of minutes at cruising speed it would then become closer to ambient but never fully ambient as that manifold can cook eggs on it and it becomes an oven for the aftercooler inside of it. You are then recirculating hot water all the time.
People have tried bigger hoses, bigger storage tanks, bigger pumps and bigger front mounts. Another thing is to get that storage tank out of the hot engine bay. If you really want a low pressure drop water to air you would need to pipe it so the aftercooler is mounted in the front bumper and not in the oven manifold. Like a barrel style.

I contacted Plazmaman (located in Australia) regarding making a custom barrel style secondary w2a I/C that would mount directly after the SC'r.(There is room enough to do this - but you are limited in size and therefore cooling capacity)
The idea here was to augment the Stillen aftercooler by initially cooling the charge before the TB's .
The barrel style I/C's don't drop much pressure, so it might have worked.
The Plazmaman custom w2a I/C would have been fairly expensive but they promised a quick turnaround.
I also considered an even larger Heat Exchanger than the Frozen Boost, and a larger circulating pump, to provide more cooling potential to the Stillen I/C itself.
