yes, probably. but here in Washington state they will also fail a car
with too low emissions. they then assume something else is not working
correctly.

I always understood that with the valve overlap necessary to produce
optimum
power, some unburnt fuel would be left in the exaust gasses. The purpose
of
the airpump was to inject oxygen into the exhaust port of the head, where
the
heat of the head, combined with the extra oxygen would promote the
burning of
the gasses. In this way the airpump was supposed to reduce HO2 readings.
However, the thought does occur to me that if a side benifit was a way
to
cheat the percentages, couldn't we install a smaller pulley on the
airpump so
that it would increase the volume of air as you said? Or, perhaps hidden
somewhere under the car, attatch a fitting to the exhaust pipe hooked to
a
more efficient air compressor, and REALLY throw the readings out of
whack!!!
