Need advice on a crazy injector Idea.

.Ok,my set up is an Fc engine,Fd Upper.putting a t70 on.
currently I have 720'sX4,not running,.scratch that thought for now.
this is a my Brain storm Idea that I need advice on:
..My Idea is 550 and 1370 secondaries..Bare with me now,I'll explain.
the 550's would be on the Primary Rail as usual.
what I would like to Try is have 720's in the Secondary rail,BUT , wired in Series(since I can do that and make them Hi Impedance),On another Fuel rail Located on the FD throttle body Elbow,That will Come ON with the secondary Injectors when they Recieve their signal.(that is roughly around 3600 Rpm)
that is where I get 720 cc's of Secondary rail fuel+550 cc's of Fd Elbow Rail fuel=1370 CC's Total of Secondary fuel.
Does this sound Feasable in doing ?..Am I nuts in thinking this will work?
I am hoping to get some feedback on this,.whether it wil work or not.Thanks Guys,STYX.

I think that it would work for sure.. but with a good tune, and a supporting ecu, you can achieve the same result on a regularly setup fuel system..

How much power you planning on making? What ECU are you using? Frankly it sounds needlessly complicated.

Agreed with Ludwig. You're total fuel need is no where near where a complex setup.

that's the way they did it 15 years ago. (old school style) with all of the new computers there is no need for that. you can make 600+ on 4 injectors without complicating things. these are rotorys, they are hard enough to keep running without making things more difficult.

Don't run the secondary rails in series.

You'll have both injectors firing same time on different rotors.

Just run one of the secondaries in series with one in throttle body.

Also you will be running the peak and hold injectors not as they are intended.

There is alot of info around with "Resistors" and the FJO low impedance drivers.

Your basically losing performance on your low impedance injectors.
