If you try this, you might want to take care to avoid "rooster tail" exit drag.  Studies have shown that is a real significant component of drag.  Canard folks have picked up significant airspeed by making them go away.

Thanks for passing this along. It's certainly something to consider before hacking holes in my paint job. Gee Ed, how about slapping some 200mph duct tape over your louvers and let me know if you see a speed increase before you overheat? ;-)
