By practical I meant in the way of it is most likely going to be less efficient than a properly sized water to air unit, take more time and effort to make work, hack the crap out of your car, and most likely cost the same or more by the time you get done fabbing everything.
In regards to 396 being practical, it is useful on a road course when I can keep up with and slowly chase down 03/04 cobras in the top end and outrun most other things on the track in the straights. I'm hoping to post a better number this spring once I get the car tuned and a few other goodies reworked on the intake side of things.
