Very interesting. I would not have expected it to be volume limited. I have a 
73 with dual carbs, scheduled to be returned to FI someday, which uses the 
FI electric fuel pump with the FI pressure regulator set to its lo ~20psi, its 
minimum setting. This is followed by a series pressure regulator which drops 
the pressure to something more normal for a carb. I wonder if that setup 
works any better.
