PRV Intake Question

["content22207" <brobertson@xxxx>]

OK -- having just spent some quality time this afternoon working
around my intake rails (ugh), have a simple question:

Why did PhD's at Peugeot et al find it necessary to use intake rails
vs conventional shaped intake manifold? Have seen Bosch fuel injection
on other makes without upper air assembly, so that can't be only
reason. Is there a performance advantage to big air drop into the
heads? (note this happens BEFORE fuel is mixed, unlike tunnel intakes
that stick carburetor half way out of hood).

Just curious (it would be SO much easier to work without intake rails
in the way).
