I wasn't talkin trailer queens, these boys down here have some very fast street driven rides. My V10 1/2 ton will be one of my daily drivers, but it won't be treated like a work truck, more like a redneck corvette lol So your gonna try and tell me you get 21 mpg on the same boost settin that you run 11's on? I know guys with stock diesels who can't get 20 mpg if they tried, modded that seems to get worse. I am bettin that my V10 will get as good or better mpg then the 5.2 with 18-20 mpg on the hwy. it is however not 7400 lbs, so if yours really does that, that's incredible. I plan on making my serious power increase up with nitrous, that way it can be a mild big cube motor that will be reliable and last long, but have that killer power when I need it.

 

You'd be surprised......

Tuned right, you get better mileage on the higher power levels than you do on the lower ones.

On 30 gals of fuel, I normally get 520 - 530 miles in day to day driving (usually with the power turned up and not driving very conservatively) and have gotten as much as 630 on the highway (duration turned down, Tq Mgmt reduced, timing increased).

Now....if you're runnin around rollin coal all over the place, you're mileage will suck.

But yes, I have the power cranked up most of the time, unless I'm doing nothing but a long distance trip, then I turn the electronics down (mostly the injection duration).

What takes 10 minutes to tune on a diesel, takes replacing parts or reducing displacement on a gas engine.

 

BUT remember that's an advantage of bein turbocharged, not really the diesel engine itself. Which is sort of my point I was tryin to get at in my adult "ADD" way lol you can boost anything and get insane amounts of power with little to no work if the bottom end is stout from the start, look at those supras. If you have ever driven a non turbo diesel, you will know that turbo is the modern diesels saving grace.

 

I'm not reading your guys long-*** posts.

 

Oh, I know what a dog a non turbo'd diesel is. I have many of them at work.

The mileage mods on a diesel don't really affect the turbo, they affect the fuel delivery. Mainly the timing, duration and injection pressure.

Add some timing, decrease duration, increase injection pressure and you get better atomization of the fuel.

That's on any electronically controlled diesel, NA or TD.

Now, on something like a 12V, a non turbo'd 7.3 or a Chevy 6.5, it's all hard parts and the same rules apply to them as they do to a gas engine. It's not as easy to switch back and forth.

Mine is compromise of max power and max mileage. I don't run enormous injectors, but I do run twin injection pumps and moderate size injectors with 2 additional holes per nozzle. Instead of one huge turbo, I run compounds. A TC that is mated to the engine Tq curve. Instead of nitrous, I use water injection. Mutiple electronic mods that adjust different parameters rather than a "one size fits all" programmer.

 

probably a good thing, you might not understand half of it anyways lol


coal train lost me on that last bit since I have never fooled with a diesel, but i sorta understand it

 

Why would you say that I cant understand them? Is it because I'm 13 and you think i'm stupid?
I can understand his post.

Your first long *** post is so long that it hurts my eyes to read and is hard to follow. You need to edit it and put in spaces like I have in this post to seperate your main points.

 

Had a post here that might have been a little too harsh, didn't realize you were actually 13. I still remember bein 13, so no need to go any further with this. Glad your takin a interest in American trucks at your age, keep it up and maybe just tone down the language a little bit. You'll come across better to the rest of us old farts who don't know nuthin.

 

haha, one thing that bothers me is when someone buys a diesel truck and doesnt make it work, and 150k on a motor is ****, you can get way more out of a gas engine now adays, there nothing compaired to a diesel, but thats not a fair comparison, my 5.9 got me 220k and its been bagged the entire time, they are great motors, just a very ****ty head design, my recomendation if your looking to make power change heads you will gain amazing amounts and also mileage, and my dads 92 ctd it has hi performance injectors and 800000k (i think thats the correct zeros) and still gets 32 mpg

 

Diesels are built with turbos..ment for turbos used with turbos for a reason..a diesel with a turbo is stock. A diesel w/o a turbo just..doesnt work. Thats like running an engine w/o a carb or TB. Just..no.
