With a diesel you don't have to tow sensibly or do maintenance?:B
And your friend bought a 6.7L Cummins in '06?:h
900,000 km and not even a water pump? That's unbelievable!!! :E - bmanningExplorer

I seriously don't buy it that a diesel engine is any longer lasting or more reliable for the engines they put in a light duty truck. The engines they put in light duty pickups are not the same they put in class 8 trucks, container ships, locomotives, bulldozers, or any other commercial application. Just because the engine in a class 8 truck lasts a certain number of miles doesn't mean because it uses the same type of fuel, the light duty pickup engine will do the same.
The diesel heads of this site regularly do the folks who come on here looking for advice a disservice. They tell them they need a diesel, so the person goes and spends 9k more for the diesel being assured they need it and it will last forever. When it will last no better and a gas engine will do the job also.
Just a few minutes ago a diesel owner made a post that his diesel truck only lasted 100k and he was led to believe they lasted a long time. Could have probably saved himself enough cash on that diesel purchase that even if he got a gas engine and even if it failed he could have bought a new engine.

Ford V10, GM 8.1L.
No surprise there; it's a great engine. - 6dot6Explorerlol black smoke does not equal more power. what it does equal is epa problems which have pretty much fined just about every tuner company doing deletes. my truck barely smokes down the track... guess i have a slow truck. dedicated pulling trucks/tractors are not the ones towing rvs or driving on the road. those trucks billow smoke because they are beyond a street applications fuel ratio and actually at a point where they are cooling the motor somewhat with extra fuel. completely different animals.

Fck it. Everyone else is jacking this thread. http://www.dieselpowermag.com/features/ford/0901dp_1994_ford_mustang_duramax/viewall.html Now what?
How about a CumStang
Perfect example of having to spool the turbo. In the Cumstang video you can here it and see it clean up once it spools. Then when he launches it's clean. - wilber1Explorer

Unburnt diesel comes out as a blueish/white smoke, not black. Ever remember walling out in the morning after starting the ole 7.3 and thinking, "man it got foggy all of a sudden"? LOL! The black smoke is actually burnt fuel just not burnt clean. You can clean it up with more air but you will have to get a bigger wheel and then it's hard to get the turbo spooled up. That's usually what takes them so long to get going at the track, getting it spooled up.
Makes sense to me. That's a problem with all turbos and why you see some manufacturers going to multiple smaller turbos and twin scroll turbos instead of one big one in order to reduce spool up time. - transamz9ExplorerUnburnt diesel comes out as a blueish/white smoke, not black.

How about a CumStang - ryhedExplorerWay back when diesel was 30 cents cheaper than gasoline, it was a real easy choice. I think we could all agree on that. A good diesel with proper maintenance will outlast most gas engines by more than 100k, can we agree on that? That being said, cost of diesel vs gas and diesel maintenance vs gas and also engine price differences, I think they come out about even in the long run, unless your gonna dump it fairly early. It just comes down to preference. I like the idea of being able to move my house off the foundation if I need to, I drive a diesel.

ROTFLMAO, you need to tell THESE PEOPLE that they are doing it all wrong. Tell them to turn there pump down because in your words "unburned fuel doesn't make power." "It just makes smoke." :R
Here is a PRO STOCK TRACTOR that needs some tuning tips.
I used to race THIS TRUCK all the time. You need to come over here and tell Brad that un-burnt fuel does not make power. If you could tell him how to keep the same power level, I'm sure he would love some tuning tips to save on the fuel bill. :SThe unburned fuel causing the smoke is helping cool the engine, not making power.
Oh brother. :R
Lets try this. Put an EGT on a diesel and then start throwing fuel at it. According to you, the EGT should go down because "unburned fuel causing the smoke is helping cool the engine." :S Lets see how that works out. :S
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.
