I'm sorry...you've lost me. Surely flow rates are a secondary consideration...i.e. ideally you size an injector to give you the flow rate you need to achieve the optimal AFR for a given load and engine speed and no more, thus giving you the best resolution possible at the bottom of the map...right?

Do twin injectors give more power? In my experience, they're ususally used when a single injector is so large that its output at very low duty cycles is unstable, making for a lumpy idle, for example.

If twin injectors *do* give more power...all I can think is that it's related to distribution of fuel within the airstream. Standard injector placement is non-optimal, in my eyes, whereas the F1-style "in front of the ram pipe" is healthier.

cheers
