Message: [QUOTE="ja_cain, post: 1316928, member: 11928"] This is the response I received from him when I asked about efficiency. In his mind, I think it really boils down to being inside an optimal injection pw window. I would like to see what the pw is on an injector with 200% nozzles making 500 hp. Also, what is the smoke output? If it is smoking, then it is not running efficiently. "Up to a 100% nozzle I would say your power goal should be sub 300rwhp. If you intend to make more power than that and do it often efficiency would be higher with a 200. My 550 was running the exact same set of injectors that are in my crew cab now and they had nowhere near the towing power that they do now with the 200's. The turbo came over as well, so the setup is identical on another motor with 200's vs 100's. The part that hangs people up is that just because a nozzle CAN make up to xxxx horsepower, doesn't mean it's efficient doing it. Kind of like a turbo that can be pushed until flames are blowing out the discharge.... a larger turbo would run in the same setup and do it much cooler." [/QUOTE]
