Ram air is only as useful the allowing air to get to your
carburater faster but is not necessarily used. When your piston is
on its intake stroke(vaccum) your combustion chamber can only draw
in enough air that is in conjuction to the chambers volume and all
other air that is present after the compression stroke is exported
to engines smog devices and is recirculated only AFTER being
filtered. All engines come off the assembly lines, be it an
airplane motor or a vehicle motor, to draw the amount of air that
it needs to run at opptimum performance. Ram Air is a myth and
don't try to throw "turbo" into the conversation because turbo is
recircualted exhaust and still has unburnt fuel in the fumes.

I think you are quite wrong. Ram air in fact gives us a half inch
or so more manifold pressure, and that increases the total weight
of the air-fuel mixture in the cylinder. Reduce your 'it doesn't
matter argument to an extreme to see how it fails.

As for turbos, the turbine is powered by the exhaust gasses coming

from the engine, the exhaust gas itself is not reintroduced into
the

cylinders. The turbine itself could be powered by an electric
motor, for that matter. That was the model for my tongue in cheek
comment about using a shop vac to increase manifold pressure.

will you marry me?

dave the term is not foo and bar.
foo *is* a term from another war and another airforce
but the term you've so successfully stuffed up is fubar
fubar is a vietnam era acronym of F***ed up beyond all recognition.

your sig line is a snafu
(situation normal all F***ed up)

Yore 'rong. foo and bar are metasyntactic variables. They aren't
acronyms (they're metasyntactic variables).

Like being the John and Jane Doe of computer engineering -
placeholders.

Fubar predates WWII.

dont agree.
foo for instance is a quite infamous cartoon of a guy peeping over a
fence with the line 'foo was here'

BY the way, the Foo was here thing was a corruption of th eorignal
Kilroy was here. no idea where that started, but it was everywhere for
years. Foo was here was a minor variation.

they are fascinating pieces of folk history so when I find one out it
sticks in the memory.

Kilroy was a government guy pressed into the task of inspecting the
quality of the hastily built cargo ships the americans turned out for
the shipping task to england. he had no way of remembering where he
had previously inspected so he developed the habit of chalking 'Kilroy
was here" to remind himself of sections he had already inspected. the
internal sections were eventually welded into the structure.

weeks later when torpedo damage was being repaired the workers would
cut away sealed parts and find the mysterious chalk marks "Kilroy was
here". the endearing puzzle being how did they get there in sealed
sections?

the mystery was explained a few years ago in a news radio segment
where someone actually tracked down the guy and got him to explain the
riddle.
