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'

foo is the 'forward observation officer' the guy who used to tootle
over the lines in an auster or a cub spotting for artillery and
fighters. verrah verrah british ol' chap. verrah verrah courageous
flying too boot.


Actually, "Foo" came from Smokey Stover, and was a corruption of the
french "feux" ( Smokey was a fireman) He called himself a "Foo fighter"
and juxtaposed with the term UFO (which at the beginning of it's life
just meant anything that pilots couldn't identify and had nothing to do
with little gray men) a UFO became a foo fighter to USAAC pilots in WW2.
While I'm sure the Forward Observation Officer thing is also true,
Smokey Stover was really popular at the time and was the source of a
large number of slang words used during the war.
I always loved his car!
