Thanks all - consensus seems to be that more air will suck more fuel and
will make more power. If this is so, why would Holley make a jet change set
and why wouldn't one size fit all?

A A Subject: [DeTomaso] Theoretical question of the day
A A Will a carburated engine make more power by simply installing a
freer
A A flowing air filter with no changes to the carb? Or removing the
filter
A A for
A A that matter?
A A A fuel injection computer will adjust the mixture to be able to
take
A A advantage of more oxygen, but fuel flow in the carb is limited
by jet
A A size.
A A I'd expect a small increase in power to be possible but the
fuel flow
A A will
A A soon be limited by jet orifice diameter, and it won't make much
more
A A power
A A despite the extra air.
A A A significant change in airflow would require rejetting the
carb to
A A take
A A advantage of the improvement, right? Or wrong?
A A Thanks all!
