In general terms, this is the way to make more power in any engine -  
pump more air in and out.  That's why racers are always trying to turn  
more RPM - more strokes of the pistons means more potential airflow.   
Of course, that leads to more cam timing, bigger ports, etc.  Or, you  
can go the bigger engine route - again, more air in and out.  Pick  
your poison :-)
