throttle bodie injector possitions?

[fred rowland]

I am in the process of installing a set of hayabusa throttle bodies to my f7r powered 5 but am having a bit of a :scratch:!
does anyone know if it is okay to keep the injectors in the head as oe or should they go in the actual throttle bodies themselves?
thanks peeps!

you want the fuel to be as atomised as possible, as in a fine a spray

I've seen a twin injector setup on a throttle bodied F7R before, they had a set of standard injectors in the head for all the low down fueling but after a certain amount of throttle they switch off and a second set mounted pointing down the throttle bodies cut in

If the throttle bodies have the injectors in them already I would prob fit them there, could make some plugs for the head and plug the original injector holes up

Can't use 'standard size' injectors in the busa bodies, you have to use pico injectors to go in them.
Btcc cars had 8 injector setups, only really worked well if they were directed into the trumpets.

F1 cars work in a similar way with top feed injectors
