I was considering a similar set-up after seeing almost that exact intercooler in the showcase at a local speedshop in Toronto. All they do is forced induction applications that consist mostly of Talonss and RX7s. The guy told me I could sit that intercooler up and down right where the stock I/C sits, and then run the upper and lower tube configuration. He said they are good for 700 HP, but I'm very hesitant to go with a liquid I/C. When I have the patience to relocate the battery, and buy all the plumbing, I might consider it. For now, I'll stick to the nicely polished double I/C that Chris just made me (thanks buddy!).
At least someone else did it before me....so I'd have someone to learn from! Looks good Chris.....can't wait to see it at Carlisle.
