Re: Airbox Mod

[Robert W Obrien <rwo@u.arizona.edu>]

All right, all this airbox talk has got me thinking about something I
recall from a while back (on the list I think)... I run a Turbo in the
desert (as does Audidudi) so I thought an airbox mod of the common type
would do little good (except perhaps on winter nights). The idea of
getting cool air to the box seems sound. I thought perhaps a NACA style
duct within the character line on a 5ktq/200 hood would do nicely... but
then I reasoned: With CIS, on a long downhill, throttle closed, wouldn't
this blow the metering flap to full rich (thus cooking the cat and
blackening the exhaust, I'd think) when no fuel was actually required? Or
does the decel fuel cutoff handle this eventuality?

Curious as usual,
Rob
