diesel v. gasoline exhaust.

[SSpeeDEMONSS]

no thats 3.55 gears 235 85 tires and add on overdrive in a extended 1 ton ford van running loads from michigan to the panhandle/texas.



my 7.3 has been able to pull 21 with the stock trans and 3.55 gears with 235 85 tires at 65 mph with the ladder racks off of it, if i go over 65, mpg goes down. 75 turns 17.

ok, well a 6.0 still doesnt do much over 20mpg. a truck tuned for mileage can do it but not a VAN hauling a load.

[SSpeeDEMONSS]

sorry.

i mean to say, you can add 100 hp and 100 tq to a modern diesel without getting dirty.

ok, i figured thats what you were trying to say but i couldnt put it together. but then again, i cant even write sentences for people to understand so go figure.

"we dont tune our diesels with the right PSI. timing and pulse width is what makes up most of the fuel tuning."

"we dont tune our diesels with the right PSI"
I'm giving you crap but what does that say!? LOL

hmmm. yeah, not loaded with 3500 plus pounds, more like 3-600 pounds.


vans seem to always do better then pickups hiway cruise ime. and he could only do 18-19 before the gear vendors. with it tuned and the add on 23 was what it was doing. the sprinter was doing 26-27 inthe same loop but was a slug compared to the diesel ford and really the chevy he has now.

cranked up the ford 6.0 van ran 14's too btw. its 7200 pounds pretty impressive to me.

i was referring to HEUI and i even corrected myself when i found out you were talking about CR. my "fuel pressure" doesnt change on my tuning. tho pulse width and timing do!

thats funny, ive seen gear vendors added to 6.0s causing MPG to decrease because the motor falls below its power band. if it really did 23MPG than that is REALLY impressive and i have not seen that happen.

Garrett

 

[Juiceit]

lol i know buddy

Believe me i have no doubt in your knowledge! thats for sure

oh yeah, originally i had thought the same thing, and told him with the auto he would probably not be happy. with the manual i could see it working and i was wrong. after that i had to step back and look at it.


i really would like to see a few more pickups with it.

did he have an auto or manual? if it was used with manual it would be WAY out of its power band. if it was with an auto it would still be pretty far out of its range. also depends on what gears, tire size, and speed he runs. if it gets too far below 2000RPMs the mileage will suffer. it doesnt benefit from lower RPMs like a gas motor will due. the charger doesnt keep enough boost and the motor over compensates to keep the boost up with more fuel.

thats where it had to be tuned, under 75 was no benefit. at the time i was thinking the the od in the manual was .8x and not .7x where the od on the auto was .7 or .69..

iirc it run 1800 plus rpm

the 5r110 is .7 and the zf6 is .72, not a huge difference. thought the 6spd behind the 6.0 was .5 6th gear.

Garrett

 

[bobbywalter]

with a .5 in the manual its perfect in that situation. i dont think the manual 6 spd was available in the e series then or i would have suggested it, but a manual isnt what denny would use which is what i would use in any case even for long range cause them hills can be tricky in the fog.

Your just showing how little you know about a modern diesel. Buddy I've pulled loaded tractor trailers out of my jobsites with my truck.

I love you light duty diesel guys that think they can get the job done. ya look at me I spent $50,000 on a pick up and dumped another $20,000 in mods on it and i still can't do what a $20,000 used International 9200 can, and I am blowing so much raw fuel out my gay looking stack that I barely get better mileage that a W900L with a 3406E cat.

yeah I read diesel power too. my mechanic's son has a 2005 duramax that will break a dino and he can't tow anything because when he tries the transmission dies. you couldn't pay enough to haul a decent load (for profit) with a 6.0L powerstroke. I talk to those RV hauler guys and they all wish for a Freightliner business class but they are so burried in their light duty diesels that they can't afford one.

I use a 96 chevy 3500 with a 6.5 turbo to move a 23,000 pound boat. I do it not because the pick up gets better mileage (it doesn't by the way, it gets 10 mpg towing the boat and my tractor gets shockingly 10 mpg towing the boat) but because the weight is so well balanced on the boat trailer that it puts not enough weight on the drives on the tractor, makes stopping difficult. so yeah you might be able to pull a tractor out of a job site........ I used a Dakota to pull a loaded tractor trailer out of a blue beacon washbay........ but your pick up would cry its dieing breath if asked to move 80,000 pounds from NYC to Las Angeles CA. so go ahead talk smack about your light duty diesels but to me it is as annoying as that kid down the street with the riced out honda lawnmower civic thing.

by the by.... I can pick up 2mpg in that same Chevy 3500 by slowing it down to 60mph.......... same principal also applies to my wife's minivan...... it will pick up 6 mpg from slowing from 75 to 60.

dont know of alot of guys towing 26 k..let alone with rangers....and i wouldnt use a 6.5 for that


so the 6.5 wont do better mpg then the tractor unloaded? and a 454 gasser or 351 out perform it as well?


my vans usually have 3000 pounds of shit in and on them, my ranger is right near 6 k empty, and professonal hauling over 15 k still doesnt matter for the topic, these guys arent bullshitting about he exaust applications, what does my truck is bigger then yours have to do with this? especially when the same rules apply to the exaust comparision?

a 6.5 towing 23000 pounds? haha, NOT! if you read diesel power and take it all serious than you dont know chit about diesels. that magazine is a bunch or crap. they misinform about trucks all the time. post pics of the wrong truck. you want to have some knowledge about light duty diesels work on one. tune it. then you can talk. as for hauling/towing large loads with a light duty truck, well, they werent designed for that. guys that try to make them do what medium or heavy duty trucks should do(like towing a 23K boat with a 6.5) are stupid! i would like to see a duramax that can break a dyno(not dino). unless he is running on some little POS dyno, there isnt one out there that can break a dyno that is designed to handle the power. also, if his trans cant take it then he hasnt properly built it. a well built transmission can handle the power that these modern diesel engines can put out. ANY light duty truck would "cry its dieing breath" trying to tow 80k from LA to NYC. you must be really IGNORANT to think that guys do that. lets keep it within the GCW and see whats up.

you are more annoying than ANY ricer with a fart can exhaust so go back to your 3500 6.5 turbo diesel or 3406E or whatever it is that you have. come back to this conversation when you have actual knowledge.
