Message: [QUOTE="Charles, post: 1295400, member: 103"] So if you don't totally stretch every nozzle all the way out until you're damn near spraying fuel out the exhaust valve with a 5 story wall of smoke behind you you're just not doing it right or what? If the stock nozzle on a 6.4 is capable of over 600hp why do you suppose they were selected for an engine that only produces mid 300's??? Why on earth did the 6.4 come with a nozzle selected for 350 or so hp that you and yours could stretch out to 600+??? Because in order to make that 350 efficiently, the nozzle didn't need to be spraying over a massive window trying to melt the pistons into the ground, spraying all over the cylinder walls with timing trying to get the event kicked off early enough and rolling coal in a stock truck just trying to run rated power like a moron. Picking up power, lowering egt, lowering smoke, increasing how crisp the truck responds..... Yeah, that sounds like a waste, lol. Gee, why not just leave the stock nozzles on and drive around smoking like a train and running hot and doggy attempting to make the same power. Obvious answer? Because most people like power to be higher, not lower, egt to be lower, not higher and smoke to be lower, not higher. Captain obvious right? You on the other hand want to take the new nozzles that CORRECT the problem the stock nozzles had of being too slow and dick them into the ground just like you had your stock nozzles dicked over by stretching them out as far as you can, possibly to the point of actually LOSING power compared to lower pw values and then blaming the charger setup over and over again. The only reason the pw values run on the stock nozzles were run was to compensate for the nozzles being too small! Not because more injection window makes more power! I already said you people must be tuning poor because so many of you try to fix tuning problems with hardware. Secondly, increasing power doesn't seem to be the problem. I mean why are you not running 1500+hp all the time? Just half-assing it or what? Obviously a setup and state of tune are put together to match a power goal. Your idea seems to be to drain your bank account upping components. Do you depend on your bank account to pick a power goal for you? Most people pick a power level they feel they can support maintenance-wise in terms of trans, engine and related driveline component failures and failure rates for the intended use. On a DD the acceptable broken sh*t all the time rate usually dictates the power goal. Pick a nozzle efficient at the power. Not one that can be pressed to it's very limit to barely get there while rolling massive coal all the time, but one that can do it as easily as possible while still delivering the most acceptable idle and part-throttle driveability. How does a turbocharger fix the overtaxing of his injection pump? How does it get the rail to pw ratio back in control so that he can finally move his right foot and get some rail without killing everything off with the program also calling for pw that cancels it right back out???? It doesn't. Because the turbo isn't the problem. The turbo just helps mask it. [/QUOTE]
