"Pump more air in".  But for Corvairs, this means  cooling air as they are 
cooling limited FIRST!  To improve cooling,  the cylinders and heads need 
to 
be more expensively redone with finning  more like an aircraft engine.  As 
they are, they are economically  cooled and run just fine that way but will 
never deliver300 hp in a 24  hour roadrace.
