Ideally the fuel would go in via direct injection into the cylinder after the intake valve was closed.
2)By its very nature a carb has to create a low pressure zone to suck the fuel through the jets, creating a flow restriction. EFI does not have this problem.
3)Now the factory EFI stuff was designed for good emissions and low end torque. 4)On Hp it does not compete with a carb. 5)Most of the aftermarket stuff is patterned off the factory systems and still trying to meet emissions. 6)It would not surprise me at all if an aftermarket EFI system, that was design from the ground up to make power and not care about emissions, made more power than a carb.

1)That's why manifold designs(wet vs dry) are different.The amount of air an engine can pump IRRELEVANT to the fuel system.
2)And yet,it(the carb) still makes as much(or more) HP as FI.Go figure
3)Factory EFI was designed for emissions-PERIOD.
4)Yes-it does.Look at all the Viper,Vettes & such.But we aren't talking about factory-are we?
5)False
6)Too ridiculous to respond to.
