That ITB air scoop shouldn't be any bigger than it needs to be - any larger you just make drag and not 350hp might need 4"-4.5" of intake area? Maybe I'm over estimating that even.

Picking up air from the centre of the front bumper would be the way to go IMHO, that's the single place on your car where the air pressure is highest. This is also where it would produce almost no increase in drag, in fact I don't see how it would increase drag sucking up air from a high pressure zone.

Don't know too much about these things, but I would have thought ITBs sucking free air isn't as good as a properly sized/tuned plenum, you can then run an intake pipe to pick up a nice ram-air effect from your bumper.
