Ok, some of you may be thinking WTF?! when you read the topic, but I've been toying around with the idea for a while now and just for the heck of it I did a search and found this:

Take a look on the bottom where it talks about the dual intercooler setup sometimes running at 100% efficiency. Now, As far as I know, that's technically impossible for a single intercooler, but I don't know about duals, it might work. Anyone have any experience on the subject?
