I was thinking that one way to get some sorta-free air for this would be to redirect the turbo's wastegate. They're talking about big rigs, and they're all wearing great big turbos, so you know they can generate some decent volume. Most of the time, they're loafing along at cruising speed and there isn't much demand on the turbo. I think there's more capacity there to be had, just a little bit of extra plumbing and a few lines of code between the turbo and the throttle position sensor.

Not sure about that last bit vis-a-vis big rigs.
