Choosing injectors for the dual configuration
Two large-body injectors will not physically fit in one pair of ports. The proven combination is one larger atomizer-style injector paired with a 2600cc in the second port. That pairing has produced 1580hp on a B series on a hub dyno.
If you are planning around two large injectors per cylinder, check the physical dimensions before ordering — this is the most common sizing mistake on this flange.
