Stillen Air to Air setup

TopgunZ

I have never seen or heard of a copper cooler. They may exist and yes copper has better heat transfer rate. Its probably a cost thing. It would be insanely expensive to manufacture vs aluminum. Water is more efficient but once it heat soaks its done. On a track it will never cool back down in time to make it useful. 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.

hmm. yeah cost of copper isn't cheap at all. Tank outside of the engine bay would work well. I'm sure there's a lot that can be done with water, including going to a liquid which is insulated better (like a glycol-DI water mix). Obviosuly using plain tap water will cause the liquid to gas and leave sediment behind quite quickly, haha. Now that I think about it more, I've worked on systems where liquid can be extremely efficient, but the cost of setup makes it ridiculous sometimes...

Z&I

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.
