Is this a thing?

This is a complete shot in the dark, but...

I want to do a custom (read: homemade mickey-mouse) cold air intake, and I was looking for a pressure diagram to show me where the best place to locate the intake would be. I know I have seen them around, but I don't know if it was just a one-off for somebody else's project, or if it was from a website somewhere that actually did them for different vehicles. Anybody know anything?
