Actually there might be something on the market that would work. It's made by JAZ Products. The 10.5 Outlaw Street guys use it all the time. They mount it under the hood and use it to supply fuel to their mult-stage nitrous systems. I was thinking of taking that tank and splicing into the lines running to the stock heat exchanger just like you would when adding a second tranny cooler to a stock cooler system. The cell is 6"X6"X12" in size. That's length, width and height respectively, and it has a 1 gallon capacity also. My friend's Cobalt SS has a ton of room under the hood on the passenger's side. Is the Redline the same way? That tank would probably fit perfectly there, but I haven't done any measurements. Putting that tank in the line on the return side of the heat exchanger would drop charge air temps significantly with ice added to the tank. The only thing is that in the winter time and your area is prone to freezing would have to have a coolant/water mixture, and you would dilute the mixture with every addition of ice. This would make it difficult to maintain the proper coolant water ratio. But we live in central Florida where it rarely freezes, so we don't have to worry about that. Also I was thinking of adding a drain valve to easily drain and fill the system. Water would be the ideal and primary cooling medium, but just in case he wanted to trek up north in the freezing cold his intercooler system wouldn't freeze and be completely ruined.
