iv been looking at intake manifolds and the edelbrock has the one manifold with the secondary fuel injector ports. I was wondering how that set up works, such as splicing the fuel to both rails and the computer setup is it worth the trouble?

 

instead of using both sets of injectors, some people opt to block off the main injector location and use the secondary one only for a cleaner look.

 

the other bungs are there for 2 reasons.

people running alcohol, because 1 set of 1600's isnt enough,
or people that use 2 sets of smaller injectors instead of 1 set of large ones.

to get fuel to both rails, you would come off of the pump with like a -10, split it with a y to 2 -8's, feed each rail with the -8's, off of the rail with -8's to each side of the reg, then the center port of the reg back to the tank.

 

alright what about wiring the second set of them can u splice off the main ones, i was told or heard u need a separate system of some kind

 

you need an ems with 4 more injector outputs to do it right.

 

who makes the ems ?

 

aem can do up to 10 channel i think, all the other real stand alones that DONT use a honda ecu can. motec, f.a.s.t. dfi, big stuff, electromotive, most of them can atleast do 8 channels.
