By adding a larger resesivor you now have a larger pool of coolant to draw from therefor having the overall temperature displaced over the greater amount of coolant keeping things cooler. When you look at the stillen tank, it looks smaller then a water bottle. The other advantage is having an icebox for track days.

My advice is to read on an svt forum, lots of info on there since they all run/start off with exchangers.
