My interest in this thread was initially as a bit of a lark. "Intercooler on and N/A, haha". But you have really got me interested now. And that's why I'm asking the questions I'm asking. You've presented a setup that is a little unusual and yes, my first response is that it doesn't make sense. But I hope by asking the questions I'm asking, I'll get a better understanding of how you came up with this setup and why you went with it. After all. Isn't that why we're all here. To learn and educate each other on the cars we love?
