Hi John,
        Well, 2.1 Liters is 0.0742 cu/ft. At 5000 RPM you would draw that volume 2,500
times a minute, so that would make about 185 cu. ft./minute. Each cylinder would be a
quarter of that (about 46 cu. ft./min). Improved vaporization of fuel is what fuel injection does.
Direct injection does it a bit better, but those are pretty recent. I would guess that putting in
new injectors might help a little bit, but not more than 5 - 10% unless your injectors are really
bad.

Henry
