It is possible to run an engine with no device at all to measure the
airflow.  This is how the holley projection works.  It is simple.  You
simply measure the throttle angle and rpm and reference a map.  However this
map must be very accurate.  It is quite commonly done on engines with little
vaccume like morotcycles and highly cammed race cars.
