You're showing smooth looking prototypes, talking about temperatures, and saying you're very excited. If I had to guess I'd say you KNOW you're on to something good. It will be interesting when you get some numbers together. You didn't mention any downsides yet other than the obvious cost and work involved. Cost should be easily taken care of when compared to cost of thermal failure.
Now that you've got the intercooler in there you'll have to work on a turbocharger next.
Have fun Wayne.
