Turtle, your arguing for the sake of arguing. What is your point? Obviously you know that fuel requires air in order to burn and more air allows for more fuel which yields more power. You can dump all the fuel you want into a 2 liter naturally aspirated diesel and there is no way you're going to get 600 hp out of it. When you care nothing about efficiency, as in a racing application, you will run at a lot higher fuel/air ratio which will produce smoke. So, yes, taking a road vehicle to the track and injecting more fuel without being overly concerned about more air will yield more power to a point but so what? Back on the road the fuel economy will drop to nonexistent, the DEF will plug solid and then what? The point is if you want more torque out of a diesel TV you need more air/revolution to allow for more fuel/revolution. Turbos accomplish that.
Not doing that at all. When someone makes an ignorant statement I'm going to call them on it. Simple as that.
When someone says that " Unburned fuel doesn't make power. It just makes smoke gas or diesel" that is an ignorant statement. Why? Because either almost every diesel puller and racer in the world is doing it wrong and has a bad tune or this persons statement is correct. Now seriously, who do you think is correct? And who cares if it's a race engine or a stock engine? It makes no difference. More smoke = more power, simple as that. If you don't believe that then go argue with the people that race diesels. You will get laughed out of the pits. Or you can argue with an old trucker that turned the fuel screw up. He will also laugh at you.
I never said you can get a infinite number of HP out of a diesel by throwing more fuel at it. What I did say is the more fuel you give a diesel the more power you get out of it. That is how a diesel works. It doesn't have a throttle plate. More fuel, more power, more fuel, more power. The limit is melting something, breaking something, or hydro lock.
Let say we have two exact mechanical diesels. 2 liter or 200 liter your choice. Turbo or non-turbo, your choice. Now, I turn the pump up on mine, it smokes more because it is getting more fuel. Which is going to make more power? My engine or yours?
Diesels are rated at fuel burned/hour. The EXACT engine can be rated at several different HP'ers. Take my 6.5L turbo engine. It is rated at 200 HP. There is the same engine rated at 180 HP. The only difference? They jack up the fuel in mine over the 180 HP model.
That is how they get more HP out of different engines. They throw more fuel to them. Most engines have a data plate on them that says the amount of fuel / hour burn rate or the pump flow rate.
Turbo's do different things whether you are talking about a gasoline engine or a diesel engine. It's very strange that the same thing can be so different on different type engines.
Diesel engine with turbo:
The more boost you run the less EGT's you get. (too an extent)
The more boost you run you won't make any more power with stock fuel settings. You just cool things off. No to very little power gain.
The more fuel you put to a turbo diesel engine the hotter things get and the more power you will make.
Gasoline engine:
The more boost you run the more EGT's you get.
The more boost you run you the more power you will make. Big power gain. You can double or triple air flow through an engine and double or triple the power of an engine.
The more fuel you put to a turbo gasoline engine (past around 10 to 1) the cooler things get and you will hurt power.
So as you can see, gasoline engines and diesel engines are very different in the way they work.
