[DeTomaso] Theoretical question of the day

Charles, 

I'd expect that the increased air flow would pull more fuel from the jets at the venturi.

Will a carburated engine make more power by simply installing a freer 
flowing air filter with no changes to the carb? Or removing the filter for 
that matter? 

A fuel injection computer will adjust the mixture to be able to take 
advantage of more oxygen, but fuel flow in the carb is limited by jet size. 
I'd expect a small increase in power to be possible but the fuel flow will 
soon be limited by jet orifice diameter, and it won't make much more power 
despite the extra air. 

A significant change in airflow would require rejetting the carb to take 
advantage of the improvement, right? Or wrong? 

Thanks all!
