Hi all , of late I've been looking into unmodified split or twin spray EV14 injectors because they are supposed to work better on 4 valve engines .
Firstly unmodified . EV14 injectors were the ducks guts when they first turned up and then mobs like Injector Dynamics and others found ways to remove the caps off their tips and increase their flow rates . Thing is the atomisation is probably better with the multi hole cap on and these days you can buy them standard in higher flow rates without the circumcision .
I think there is an issue with a single spray injector and 4 valve per cylinder inlet ports , probably not the best idea to be spraying at the port divider when you want the atomised fuel air mix heading towards the inlet valves . I found some info at Air Power Systems and they show pics of Ford XR6T inlet ports and these look like they have twin paths cast into their inlet ports for twin spray injectors .
I'd like to hear what people think of the twin spray injector idea .
Cheers , A .
