Message: [QUOTE="Chris, post: 38519, member: 400"] Youre right, im wrong. Navistar should have put 200 percent nozzles in from the factory and with 400 percent nozzles we are 500 hp ahead of the cr cummins and dmax guys. What was i thinking. Having less time to burn the fuel and make power per cycle happens in every engine. The common rails just get around it a litlte better. Not because of their pure volume, but of the volume theyre actually able to burn and convert to horsepower. I never said youd need the same volume out of the 100 to make the same power in the same duration as a 200. the 200 will always flow more fuel into the motor. What im saying is if you COULD burn more of the fuel injected more efficiently, you COULD make more hp with smaller nozzles. Also youre comment about the 12 valve also proves what im trying to say. Why do motors w/ less air flow and less atomization need larger nozzles to make the same amount of power? thats my whole point. Im not saying the system on a 7.3 will ever be capable of making 600 hp on fuel out of a 100 percent nozzle. Theres a chance itll take more money, time and effort than converting the whole thing to common rail or swapping power plants all together. What im saying is, it would be nice. [/QUOTE]
