The opening in the lower grill is not very big.  The size of the IC 
itself is not so great and all that piping doesn't help either.
If that location is so good why didn't the rally team use it?
The rally cars had a hudge IC right in the grill.
For that kind of money don't you think they should have come up with 
a better design.  And how cheap do you have to be to run a second 
radiator instead of increasing the size of the single unit.  Tilt it 
sideways like in rally cars if you have to.  It looked like cost was 
not an object for $35,000 back in mid eighties.

If it's good enough of a spot for the rally teams than it's good 
enough for me.  Just think about it.
