Rob,
Note, the word "optimal" ...
The injectors will work just fine with no differential pressure across the
fuel injectors... but they work a lot better with some positive pressure
differential.
This is one reason that turbocharged airplanes with intercoolers often run
much smoother than normally aspirated engines.
You get the benefit of the pressure drop across the intercooler - - so that
the upper deck air to the fuel injectors is always at or near a suitable
"delta" for nice airflow across the injectors and better fuel atomization.
Regards, George

optimal upper deck pressure on injectors may
be in the area of a 3 psi differential.
3psi = 6 in. Hg... this means at sea
level std day, we shouldn't use more than 24 MAP?
