Message: [QUOTE="Hotrodtractor, post: 540510, member: 25"] Quick clarification 7:1 is an A-code, 6:1 is a B-code, 5:1 is a hybrid. Just because an injector has a lower injection ratio doesn't mean it will have a lower injection pressure under certain injection conditions. As ICP increases and the injection speed increases - you get a drop in oil pressure due to flow through the poppet of the injector - this pressure drop can be high enough that the lower injection ratio injector with its lower oil volume (and consequently flow) requirements can get a higher oil pressure to the intensifier. If all else is equal on a pair of injectors except for the injection ratio - if you take the ICP high enough - you will get more actual fuel injection pressure at the tip on the lower injection ratio injector. Under low ICP conditions the higher injection ratio injector will have the higher injection pressure. Hope that makes sense... lol [/QUOTE]
