PT Air Intake Change

[Pete Masterson]

I note that the air intake on the DD Series 60 engines are simply a
grate on the curb-side of the coach above the grate-style side access
door. There is zero ram effect from this arrangement. I believe that
you are correct that with the turbo system, the ram effect is
probably negligible. I would, however, concur that turning the intake
toward the rear might cause a 'negative' (suction) effect that is
undesirable.
