Twin Injectors or not? What are your experiences
Dear All
I'm putting my duratec together right now, and I am wondering what to do about injectors. I know there's a variation between outright
performance or economy (not bothered  ) depending on if you have the injectors in the head or the throttle body, but has any one got experience of
running both sets?
I appreciate that means:
- two sets of injectors
- a second fuel rail and plumbing
- a pump that has capacity
- engine management that has the functionality
I don't have a method yet of sealing the injector ports in the head, so I would also appreciate advice on that as well.
Thanks
Mark

I use 8 injectors on my car. Works well, very driveable in traffic and goes well when i poke the rhd peddle 
I used gsxr tb's which already had 8 injectors, some mods to re-space the bodies and fuel rails and they were there to use, plus i already had
an ecu that can control them however i want. Currently set-up to run the inner bank up to 5000rpm then after that transitions to all 8 over half
throttle. The outer set doesn't have the flow to run the engine at full chat so i couldn't just run the outer bank as would be the case
normally but that's something i'll address over the winter.
The fuel pump point isn't valid, you need enough fuel/flow for the engine no matter if you run 4 big injectors or 8. The engine needs what it
needs however you put it in.
