I have a few questions about an AIC. Would an AIC be able to control stock injectors? How would the ECU react to that? Generally people will run stock injectors up to a decent duty cycle then let the additionals kick in and richen the mixture after that. Also, what is an efficient way to plumb injectors? From what I've seen people plumb 4 smaller injectors into the intake manifold, but why 4? Why not 2 larger ones for the secondary ports?

When designing/building an engine, would one port the secondary ports more, or equal to the primaries? Wouldn't a higher velocity primary port (i.e. lower revs), create more torque lower down? I've heard with some bridgeported engines, people only bridging the secondaries, so that's where I get that. I guess my understanding is: Primary injectors = primary ports, secondaries = secondary ports. The fact that people run 720prim 1600sec setups would indicate that the primaries are really only designed for low end load, because 720x2 = not alot of airflow.

Here's why I'm asking: I'd like to run 720 primaries and either control 2x1600cc secondaries with an AIC, or run 2 additionally plumbed 1600s into the secondary ports. I'm wondering if there will be a fuel distribution problem if I do this, and I'd like some specifics so I can understand better.

Any help with this would be much appreciated. Thanks in advance

 

TTT. At least LOOK at the question!
