GM 6.2 Diesel???

[jaymegriffiths]

If you didn't spout ridiculous 'facts' I'd be less likely to call you out for being on crack.

You're on crack.

im not on crack. according to diesel power a stock cummins crew cab 4x4 dually weighs 8700 pounds. your right, i took a stab at the 8000 for a non dually, but never did i claim any of it was fact. although i'd swear my trucks title that that dodge can get 29 MPG highway when you drive it super nice, and i can say that it got 22.3 MPG average over 1200 km's pulling our 24? foot 5th wheel. thats using overdrive and cruise the whole way. plus its running oversized tires.

Thats fine and dandy.

But i really doubt anyone (in there right mind) would hook a 25ft 5th wheel behind an RBV.

I dont know, ive just never been impressed with Diesels. Any Diesel. Sure they get better mileage, but i myself, am plenty happy with a Rumbling Gas V8 that actually starts when its cold and doesnt sound like a 1954 Oliver.

Bobby, not to disrespect you, or will, cause i really do admire the fact that you actually had the balls to attempt to do a 6.2L swap, but if i had the time, money, and want to, i could take a 351W, or a 400, and put in an RBV and do anything your 6.2L can do. Unless you decide to chip it and whatever else you crazy diesel guys do.

If i was going to build a Ranger, it would have a Dana 60 in front, a Dana 70 Full float in back, a built 400 under the hood, with a T18 and NP203 (or 205 whatever the gear drive one is) tieing it all togther, riding on 38's and painted flat black, and it would be a Reg cab/long box 1st gen.

test drive a new VWdiesel. you probably couldn't even tell its a deisel. and i totally agree that i dont know anyone who would hook up a 24 foot 5th wheel to an RBV with just a diesel, without significant other mods. like differential(s) brakes, suspension, frame support/bed support. but if i wanted good gas milage and plenty of torque, i would definitely consider it. not that a SAS 400CI RBV beast wouldn't be cool, but it certainly wouldn't be efficient.

I'd like to see this 500hp 8000lb truck that gets 30mpg!!! Diesel or gas I'll take it...

the 8000 pounds is in question. ill have to take it to a weigh station its sittin outside my house. its not stock, but the specs are accurate. last year it was dynoed at over 450 horse, before having the programmer installed(in addition to the chip, and the truck is CONSiDERABLY faster with the programmer), a 4 inch exhaust, s&b intake with k&n filter and upgraded injectors. The chip is edge.Dont remember what the programmer is...(came in a red box, haha) to my knowledge there is no 500 horse 3/4 tonnes that get 30 mpg highway. if there was i wouldn't be as much of a deisel fanatic as i am. Cummins is by far the most efficient diesel of the big 3 and i believe it is 99% attributed to the fact that its an inline 6, utilizing the torque and multiplying it, and i believe a twin turbo version of the 5.9, NOT the 6.7 would be the most desirable diesel pickup engine. EVER. (accompanied with a 6 speed allison)

He might have been talking to me... I'm just saying swapping a good 4.0L for a diesel just for mileage sake isn't worth it... You'd be hard pressed to make the swap profitable for most people... Now, of course, if you have D60's and running big tires it's definitely worth it...

i have to agree, i never said the deisel swap was profitable, nor would i say that cause its in most cases not true. if you got a good deal on a diesel engine and tranny to put in, maybe, but simply trying to find a specific engine/tranny can get costly. plus making it work is a whole different story.

You're still on crack. No full size truck maintains 22mpg while towing a 5th wheel trailer. You're math is MASSIVELY flawed. These trucks barely make 20mpg on the highway with no load (some of them don't).

 

[rusty ol ranger]

Um lets see...

1- Converting the fuel system.
2- A 6.2L (err 6.5L) is alot larger physically then a 302/351 so more hacking would need to be done
3-Getting the front suspension to handle that much weight (but i guess in bobbys case that wouldnt be an issue, but trying to use stock RBV suspension would be)
4- Theres is little to no info on how to do the swap.

Just seems like a PITA to me.

[jaymegriffiths]

You keep referring to 'all the extra work', yet somebody who's done both swaps tells you that it's no more difficult. What work are you referring to?

in addition, most mechanical injection diesels require very little wiring to run, and the 6.2 is similair in size to a 350(i think)
but somehow a mopar v10 and 6 speed is more realistic. please explain yourself. i think we may be dealing with a little closemindedness, perhaps old fashioned ness. haha( no offense "dustin" )

 

[rusty ol ranger]

I never said it was more realistic.

....and no offense taken. I am old fashioned

...and fast, to take the other side of the coin once, he might not be that high on crack, i know a guy with a 2000 Ram Cummins 3/4ton on 38's with a chip and pump and he gets 25. Granted thats empty and driving like a grandma. So i could believe the mid 20s empty, but NO WAY with a 5th wheel.

i think i can do math. and obviously you havemnt done research lately. theres a guy in the last months diesel power who got 60 mpg out of his 1200 horse reg cab 2wd cummins. 60 FUGGIN MPG!!! i've never seen and ford or chev do that but ive seen numerous dodges getting mid to high 20's on the highway. with no wind, driving normal it gets around 27. im not on crack. i dont need to argue with you, i know what its getting, and just cause you dont believe me doesn't make it true. nor do i have to argue with you, because you can continue believing diesels arent capable of obtaining 20+MPG and over 400 horse.

With how much money dumped into his truck?

Diesels use fuel to make power. Thats why there eaiser to get power from then a gas engine, with a gas engine you have to feed it air. With a diesel you just pour in the fuel.

But it takes fuel to make power. Power comes from BTUS from burning fuel. More power=more BTU's=more fuel. Theres no way around it.

38's and 25! thats a longer stretch than my story. and the trailer only weighs like 7000 pounds its a fibreglass trailer. just like i said, 22.3 figured in US gallons, not canadian. in canadian the number is higher, but the gas you burn is still the same.

yes but lower gearing can be used in addition to the extra torque to achieve lower RPMS. on the highway my truck sits at 2800-2900RPMS. the dodge on OD sits at i think 1450-1700. plus when your making power you dont get gas milage. we dont calculate the milage while draggin it down the strip oh ya and that guy with the cummins, i have no idea, but were not discussing the porfitability of putting a diesel in a ranger, its that ability of a diesel to make incredible power while not sacrificing milage. thats what counts

it probably gets about 4 mpg when making 500 horse, but you dont utilize than til you punch it.

I'm always amazed at what people's trucks weigh. Those dually quad cabs come with everything. The heaviest option is the bedliner at 45#. A 4x4 diesel dually longbed quadcab has a base weight of 7,400#. A 4x4 2500 quadcab like JohnnyU has is 7,000# base weight. The heaviest thing I've seen from any manufacturer is the Ford Excursion 4x4 diesel which was 7,800# base. Any of these vehicles will vary some, but they come with everything.

Edit:I also don't believe the 22mpg trailer story. That's too far out from anything I've seen or experienced. 6.2s get the best efficiency of any diesel I've been around and I get 21mpg at 60mph with my truck empty and about 14.5mpg pulling 7,000#--and not a travel trailer sticking out and up, but a B2 on a trailer. Most Cummins people I know get about 16 highway--and I don't know anyone with a dually. I'd need some convincing evidence to believe it.

wanna save gas? shut off your engine when its not workin. I added a vac gauge and a kill switch to my 2wd 300 5 spd F150 was getting 11-12 mpg now its up to 20. Thats intown driving by coasting hills and not idling.

Some say I'll wear the starter out others say the clutch and hydraulics are getting excessive use. I think its fine I also think the engine gets annoyed by the frequent stopping starting, and I'm adding a pushbutton start cause the key mechanicals are fragile under normal use.

It has 4.10's which was great when I was Hualin my B2 to RC but wont be doing that for another year or two. I lined up a set of 3.27's to install in the next few weeks, That will help the Highway mileage considerably. Ya need steep hills to maintain speed while coasting in a brick at highways speeds there arent many around here that I drive on. but on the Highway it spins at 2700 pulling 27 in of vacuum. Tractor motors dont like that they wanna work! It sounds and feels 100X better dragging 5K up a mountain 3k rpms @ 60mph.

american gallon: 3.785 Liters,
canadian gallon, 4.5
still, its getting much better than 16 highway. even with a trailer i bet it gets 16+ using the american conversion. all i know is my 2.9 ranger gets 15.6mpg city using the same method and i believe the owner of the dodge claims 19-20 city driving normal.(not babying) even my work has a 199? powerstroke panel van with 613,000 km's, dont even know if its 7.3 or 6.0 but i think 7.3 get close to 15 city.
heres how we figured it out:
94$@102.9/liter=91.35liters.
devide by 4.5 to get gallons=20.3 gallons.
724 kms. devide by 1.6 to get miles, get 453 kms
453 devide by 20.3 gallons, 22.31.

american conversion:
91.35/3.78
24.16 gallons
453/24.16= 18.75
so a little lower, but youd never get that out of a gasser. and the upgrades made a huge difference in efficiency. especially the programmer cause it has a towing setting. I dunno, but its not crazy here. i know a few people with 5.9 dodges with similair or slightly lower milage.

 

[rusty ol ranger]

You only get 15 from a 2.9? Somethin is wrong.

Hell i get 16 from my 5.4L Expedition with 3.73 gears.

7400 is all a Dually diesel long bed weighs?

My buddies 2000 F150 4x4 ext cab with a 5.4L weighs like 5500.
