Message: [QUOTE="TARM, post: 1054293, member: 578"] Its true about the atomization but only up to a point and as soon as you reach the threshold between getting oil in and out thru the poppet for that larger amount of oil that benefit is gone and actually in in favor of the lower ratio as it will actually flowing more fuel from the same size nozzle in the same amount of time. If you think about if you have two injectors both with the same size nozzles one with a 5:1 and the other 7:1 plunger barrel ratio the one that injects the most fuel in a given amount of time is the one that actually is injecting the fuel at a higher pressure. See once the injectors need for oil exceeds that of what is able to get in and out of the injector it can not longer inject at a higher pressure that it could before that limit was reached. Flow bench after flow bench and real world testing has shown this time and time again. From MY perspective if you are getting your injectors rebuilt and you do not mind a chip for basic stock level with a little more pep single shot A codes 30% nozzles after that I really do not see much of a reason not to jump right to 200% hybrids from there. The latter can be tuned to give almost stock idle and running quality and can of further be tuned to any power combo up to their max which IMO is over what a stock bottom end can handle at least for long. Certainly good for 600+ hp with air in the range of a gt4294 and up. Once you step over the 200% nozzle you start to sacrifice street behavior, idle resolution/quality and clean running and without a doubt for it to me smooth needs live tuning and possibly a more than one session unless they can really spend some time on it. Again all only my opinion as what people are willing to tolerate or see as acceptable varies significantly. For me I do not believe a truck meant for the street for its main duty should be hazing at idle, puffing with every very light throttle takeoff, and cruise control should work without surging. Those things becoming increasingly challenging once you go over 200% again only my opinion. [/QUOTE]
