Factory sequential injectors are setup to spray fuel onto the back of the closed inlet valves which then causes the fuel to evaporate which gives better fuel economy and low-rpm torque.
|
not necessarily true  , it depends greatly on the particular engine involved as to what phasing is the best for power or emissions, and those two points to not necessarily coincide.
many factory injectors actually spray against the side of the ports, which helps atomisation not from the jet of fuel itself, but from the rebound/spray off the port wall
for high rpm motors, because of the high intake velocity, more time may be required for decent mixing, and time = distance. can't afford to have sharge stratification in a high $ motor (unless it is designed for it ).
for a motor which is NOT going to be run at WOT all the time, there is little benefit in fitting high injectors, and the couple of % difference will not be noticed/useful.
