[s-cars] E85

[Robert Myers]

E85 contains less energy per gallon than does any flavor of 
gasoline.  This requires that for any given power level more E85 must 
be burned than gasoline.  For our cars to use E85 we need to deliver 
more fuel to the engine.  This can be accomplished by software 
control of injector duty cycle, higher flowing injectors, higher fuel 
pressures or some combination of these.  In turn, depending on just 
how much power you are looking for, this may also require larger 
capacity fuel pumps, larger diameter fuel lines, etc., in order to 
keep up with the injectors demands.
