Sorry as I didn't fully explain my last post. He's a typical diesel in a truck is going to see around 40% thermodynamic efficiency. Internal combustion engines are chemical reaction driven. Gasoline has 8, don't hold me to that and I don't feel like looking this up, hydrocarbons and highway diesel 14 hydrocarbons. With more hydrocarbons there is more potential to make more energy, thus why diesel and heavy fuel oils are more efficient.
Turtle, your right but you can't just throw fuel at it. You have to add some air as well. If that statement was true I could just throw 100% over's in my truck and make lots of power and lots of smoke. Doesnt work like that. You need to balance timing, pulse width, and boost. I'm talking about newer common rail turbo diesels here. I'll finish this later.
It sure does. You don't "have" to balance anything. The reason you can't throw 100% is because you will burn it down. You don't have a big enough turbo to cool down the fuel load. Non-turbo is worse. They don't have anything to cool the combustion chamber off. Hence the lower power setting with non turbo engines like a 3208.
Now, it works better if you adjust all the things you mentioned, but I can just jack the fuel rate up and make good power.
Turbo, non turbo, it makes no difference. More fuel = more power. I gained around 25HP on my 6.5 just by turning up the pump.
I can take a stock common rail and "just" jack the fuel rate up and I will make more power. I don't need any more air. Now it will work better if I have more air or O2 from nitrous no doubt.
But to say I can't get more power by just adding fuel is wrong. I know a guy that has a 12V and is making huge power with lots of fuel. And that is only with 1 intake valve/ cylinder. With a small turbo you really have to keep an eye open for high EGT's or run it at WOT for only a short period.
