You seem to have answered most of your questions. Test drive all 3, talk to people who own each and hopefully they will be honest about the pros/cons.

23 mpg consistently with the dmax? I don't think so.

I have an 05 Duramax CC shortbox. I would never drive a standard everyday, I don't care what you say. I like the auto in trafffic. It tows fantastic, 23,000 miles and nothing but oil changes. I think you will find all the big three are very comperable in stockish form. I think the Duramax is the quietest of the three.

I only wish I got near 23!! Try consistent 16. If I stick around 2K rpms(65 mph) empty it will hold 19-20. Most mixed driving it settles around 17, and there aren't many times on the highway where you can go consistent 65, especially when the speed limit is 75!

If it is flat, I get 20 in my PSD excursion, if not I get 17. In the city i get 13-14. If you are going use it as a DD, no way I would do a manual. I would definatly go auto. Saying that, I would go Ford or Chevy. Dodge trucks are not as comfortable and their automatics are not as good. The Ford and chevy autos are much better... The ford and chevy are both real comfortable. just pick the one with a price you like and features you like.

Well the D-Max/6spd is no longer avaliable :mad3: :mad3: but there are some nice used ones out there. I can get/have gotten 23-24mpg with my D-Max/6spd if I keep it under 70mpg.It's an ex-cab,LB,4x4. I'm running 255"s so I'm running lower RPM's than stock. Usurally I get 17-18 combined mpg but that's running 75+ mph,driving in town and having my chip cranked up while in town. I have a hard time not playing at stoplights too otherwise I think I'd get 20+mpg all the time. I have modifyed my stock air box and I took my muffler off. I also change my fuel filter often. BTW this is all hand calculated figures. If you do get a PSD get a 7.3 otherwise it's a guessing game on reliability. D-Max will pull better ,last longer,and get better mpg. My dad has a D-Max/Ally and he consistently gets 19-22mpg. These are early ones. 01' and 02'. The 04.5'+ will not get these kind of #'s. I personally would look for a nice 01'-03'. A manuel is the only way to go IMO. Will make a auto look silly on hills and handles more power. With the Ally,you are limited to about 90hp over stock if you chip it.Otherwise you will fry your tranny which is around $4000 to have a good one built that will handle a good bit of power. With the 6spd you will need an aftermarket clutch which runs around $1000 for a good DD one and $2000 for one like mine{see sig} that will hold up to the abuse of truck pulling and high HP.

I run 165/70/13 tires on my 2nd gen CTD and get 45 mpg in my truck as long as I keep it under 45 mph. It's worth it!

Doesn't sound like you need a diesel if you're not going to tow much with it. It will take years for you to recoup the cost of a diesel over a half ton if you're looking purely at gas mileage.

I got 22 mpg with a edge oj/att on the highway with my lly duramax with stock tires. My lb7 with tts tow tune and 35's gets around 18-20. I would go with an auto. The tow haul mode works awesome. It does everything you would want a manual to do without having to push in a clutch or search for gears JMO.

Except hold speed on hill's :( . We have one of each and there is a lot of difference. FYI if you Dyno them stock,the Ally will make around 265-275rwhp the 6spd makes somewhat more. Mine made 298rwhp stock.

You always hear claims of big mileage and they never seem to pan out. Usually the people claiming these numbers are using the onboard readout or odometer to figure mileage. First thing you need to do is calibrate your speedo / odometer. There is no way a 3/4 ton 4wd auto with oversized tires is getting 20 + mpg.:laughing: :laughing:

Mileage aside, I've got an older ('01) CTD/Auto & the one thng I don't like is that the tranny hunts a little too much on steep hills at freeway speeds.

& if they're footing the bill for an allowance, I'd go with the crew instead of an extended cab. You'll be hauling lots of kids around & it's a little tight for bigger kids.

Really all 3 are good trucks, one is not better then the other, all of them have good motors and good trannys, but, dodge only has a 4 speed auto, where Ford and GM have a 5 and 6.
Just buy what you like for Style, and interior.
I bought a dodge.

Its been said, but if you are towing light loads and a boat, do you really need that much truck? I guess the question would be, what types of loads and what size boat. Last week, I bought a 2003 chevy ext cab z71 with the 5.3L, 285/75/16s and 3.73 gears with 37k miles for $18.2k. I drove it 500 miles home and got 19 mpg, and thats including sitting in construction/traffic for over an hour, that is also adjusted for tire size. 500 miles is plenty of time to calibrate the speedo using a stopwatch and mile markers :) I bought a truck for several reasons, one of which is to tow my 21' Chaparral. The boat plus trailer is somewhere between 4000 and 4500 lbs, add in gear and gas, and it will be near 5000 lbs. Truck is rated at over 7000 lbs.

My point is that I was looking at diesels also (all used prices), but the diesels were all consistently in the $25k range, more if you want low mileage. I really dont tow or haul that much, so the half ton works for me for both DD and light towing duties.

An 01?? I don't think the factory rating for an LB7 is even that high?

I've got an 05 LLY that is rated at 305 HP from the factory, and that is crank at sea level?

I call BS on that one:laughing: :laughing:

I just got an '06 CC short-bed Duramax LBZ. I use it for my DD and like it. Its brand new so the hand calc'd mileage is only 16+/- mpg. Should get a bit better as the truck gets broken in.

HP is measured at the Flywheel for the factory #'s and the 298 was on the dyno at the Rear Wheels.

I don't care about Dmax turbos because Dmax's are light duty engines. My truck has a medium duty engine.

If it was 298 at the rear wheels, it would be close to 390hp at the flywheel, hence why you are full of fucking shit :shaking:

305 310 whatever, I really don't care.

I'm just trying to figure out how your truck only loses 2 horsepower from the flywheel to the crank?

Checked on what Scott had, he said 296 to the wheels, 2wd stick. I stand corrected. Mine must do at least 301 then!

PM' me and we can discuss this or we can meet up when I'm in CO next time. I have dyno sheets with proof of 286.4rwhp stock @ 3100rpm. The Dyno only prints out a reading every 100rpm.The 298rwhp was not at an ever rpm so it's not on paper.I should have used the 286.4 so I could prove it but all the same I can prove the 286.4. Rockstomper probably can prove his 298 though. I can link you to all the dyno results from that day that I dyno'd. It was put on by the Colorado Powerstroke Club BTW.

All my #'s are hand calculated. I'm running 33" tires and so I have to add 11% because they don't go around an many times. I know about the guys claiming 28mpg but 21-24mpg is not unlikely. We currently have 2 Duramax's. Before we ran gassers. My 97' 2500 ex-cab 4x4 454 5spd could get 16mpg if driven carefully. Most of the time it got 13-14mpg. It has nothing to do with diesel MPG it has to do with facts.

I love a scared dodge boy, there is a new leader among the diesels!

Best I have gotten was 22mpg going 70mph, strictly highway on 245's and mines an auto.
I have also dynoed mine, was done on a superflow auto dyne, corrections were calculated for sea level, pickup was on driveshaft, corrections were also made for turbo charger and pressure differential at 5400 ft. Dynoed at 269hp and 477lb tq. Not bad for a stock chebby.
As for the original question, I would stay away from fords 6 liter, lots of known problems, wait till the new powerstroke is released, or go with a 7.3
Dodge has a great engine, but the rest is a dodge. Dodge autos are nothing great, manuals are much better.
Dmax is a great engine, LB7 and the new LBZ are the best. The LLY has some OH problems when using a big tune under the right circumsances.
They are all pretty good, whichever one you like best

We don't care what the duradud is doing. My Cummins is putting out enough power for me. I call BS on the mileage. No new 3/4 ton diesel truck (gm, ford, dodge) is going go do over 20 mpg. A 12 valve Cummins might be able to do it.

What kind of dyno did you use and what was the correction factor? Anyone else dyno with different brand of motor for reference?

We don't care what the duradud is doing. My Cummins is putting out enough power for me. I call BS on the mileage. No new 3/4 ton diesel truck (gm, ford, dodge) is going go do over 20 mpg. A 12 valve Cummins might be able to do it.

What kind of dyno did you use and what was the correction factor? Anyone else dyno with different brand of motor for reference?

The best I ever got was with the 2wd dodge 91's the auto would get 21 and the 5 speed would do 23 on the hwy.

I'm sure the video(s) will be available soon for any doubters. I have been waiting, hoping, praying and spending for the last several years to finally make a sub 11.00 second run.

Now that the "monkey is off my back", there are some people I need to thank for making the perfomance this weekend possible:

Steve Cole - TTS Powersystems to make the power (at the event)
Joe Webb - Suncoast tranny to put it to the ground (at the event)
Mike L
Eric Merchant - M/A (at the event)
Michael Oakes - Super Diesel (cp3 mods)
Dennis Perry & crew - TS Performance (awesome event the last 2 years - although I enjoyed this year much more than last!)

In addition, there are many others who have helped supply knowledge, ideas, parts & bs to make this a reality... Thanks to each and every one.

While it is nice to be first, I hope this club quickly grows in membership .

My last fill-up (hand calculated) with a 70/30 highway/city driving mix came out to 19.64 mpg. The best that I ever got was straight highway driving from Fort Worth to San Antonio using summer blend diesel, no AC and cruise set on 70. 23.12 mpg hand calculated.

My truck was unloaded in both instances. I run 265/75/16 tires, with a Predator programmer on the 65hp setting. The EGR is disabled.

It is a 2004.5 LLY crew cab 4x4 2500HD with the Allison tranny.

I don't care about Dmax turbos because Dmax's are light duty engines. My truck has a medium duty engine.

If it was 298 at the rear wheels, it would be close to 390hp at the flywheel, hence why you are full of fucking shit :shaking:

2006 Dmax LBZ's make 300+ at the rear wheels with an automatic, and they "only" have 360 at the flywheel. But then again, you already knew that because your truck has a medium duty engine.

All my #'s are hand calculated. I'm running 33" tires and so I have to add 11% because they don't go around an many times.

I suspect you're being generous with the 11% correction. Was 11% determined against mileage markers, a GPS or just going by the calculated increase in tire circumferance?

My '00 CTD 4wd 2500 6spd is only a ~6% correction via GPS from the stock 245/75R16s to my current 315/75R16s. The best I've ever gotten is 17.5 MPG. MY old '96 12V CTD 2500 5spd w/255/85R16s would & still does (it's my dad's now) 20-21 MPG.

i have stock tires, a custom 65hp and switchable custom 120 hp tune (based on primarily a PPE Hot tune, with some defueling between shifts to save my tranny) I noticed like a few mentioned that the tune will make the truck computer mpg incorrect, so i started hand calculating. On a 500 mile round trip, with the small tune i got over 530 miles for a tank (figuring that the remaining fuel in the tank would amount to around 30 miles), tank being 20.4ish gallons...thats 25.98 mpg. on my most recent tank, i am at 277 miles on just half tank! and i dont drive my truck light, i get smoke happy at lights. and yes my speedo has been calibrated many times...i have fully flashed my ECM over 5 times loading different tune, which i beleive also automatically recalibrates all the gauges. i will have to double check though...

Stock engine internals, stock injectors, stock turbo. I consider that "stock".

Wade runs a stock intake. If you buy an intake for a turbodiesel you're stupid (yes, I bought an intake for mine back when I was stupid too, biggest waste of money ever)

yes he has an exhaust, yes he has a chip (TTS Extreme), and yes he has propane and nitrous. Tranny is a 'Purple Palace' special. (ATS)

You are splitting hairs to consider chip, exhaust, nitrous and propane "far from stock".

"far from stock" is pistons, rods, big sticks, big turbo, basically a full built engine. Id like to see a Cummins crew cab run 11's on a STOCK turbo and stock sticks.

good luck getting anywhere on a stock Cummins turbo too..................

stock Dmax turbos have been proven to over 500 rear wheel hp on fuel only, and as IBDMAX'IN proved, 835 on nitrous/propane.

I will say that Wade (IBDMAxin) now runs a bigger turbo (aurora 5000), but he ran 11's and 835 wheel hp on the stock turbo...

I would go new if you can get an order in for an 06. The 07 diesels get new emissions and you want to check on that changeover since it really complicates things and brings new stuff to the table.

I like stickshifts, when I get a leg ripped off I will go back to driving an automatic if I have no other choice. Someone could prove to me that an automatic was made that gets 10mpg more than my stickshift, and I would still want my clutch pedal and stickshift.

As of feb this year you could order a dura-max with a stickshift, but the engine is lower powered than the engine that comes with the allison automatic. That really irks me so I never even test drove the general motors diesels.

Ford seemed like it would do whatever but felt a bit bland. Part of this is I have spent a lot of time riding in a buddy's ford diesel.

I could not find a new dodge with a stickshift to test drive. I did find an 03 a dealer had for a trade in and the previous owner had installed a banks 6 gun package on it.

I bought the used 03 with the banks package. It is a stickshift diesel 4x4 with the quad cab, long bed, and dually rear end. It is about the longest truck dodge makes. If you go with the mega cab you can only get a shortbed and it is a similar length to my truck.

I think all 3 makes of trucks have their own personality so it depends on what you want. I really prefer the 4x4 ford and dodge and having to jump into the truck, I do not have steps or runnning boards and don't plan to get them.

I mostly use my truck as a daily driver but I have loaded the bed with some decent weight and the truck rides better and stays in gears a bit longer. Overall the truck makes for a nice daily driver in my opinion because people leave me alone as far as cutting me off or tailgating. It rides like a truck and I like that. Unloaded the tires do not squirm a bit so it handles fine for a solid axle 4x4 that weighs in around 8k lbs or so with all the junk I have on and in the truck.

I only have 6500 miles on the truck so far. And parking it does take a tiny amount of thinking since it is big and long and some spots in parking lots are tough depending on how other people park. I learned about that immediately and the nice thing with a big truck is you can hop those little concrete things they use to mark parking spots and it won't hurt the truck a bit.

I think a new truck has plenty of power stock. Just because of warranty I would not mess with a new truck.

Part of the appeal of this 03 was it already had a few thousand in mods done to it and the price was pretty decent and I sort of want to mess with the aftermarket stuff on it once I get around to needing a clutch. So new was not the best choice for me, but it would have been fine if I came across a better deal that way.

But I wanted out of my trade in since it was acting up so I got what I got and I like it.

Just an aside, I am down here in eastern tn and there is a duramax crew cab 4x4 dually that is a military optioned truck. It is an automatic and has a tool box bed on it. It has that funky green paint on it and is an 05. Stick on this thing was 90k according to what is on the truck and they are selling it for 38k or so. It already has a serious front bumper replacement on it and it is painted that funky green as well. Awesome truck. I doubt I would want to drive it daily due to the attention it will draw, but it is one neat looking truck with all sorts of stuff already done to it.

Then you are an idiot. Stock means stock. You must really be new to motorsports since that is a basic classification in all of them.

And are you saying he is not running an aftermarket filter assembly AKA intake? If not, that is a good way to starve an engine and burn it up.

well shoot too bad for TacoJedbob7, cause this idiot was the guy who wrote his ECM tune. Yeah, wrote, as in made the tune from scratch. There are no factory tunes (ie Superchips, Hypertech, PPE, Quad, Edge, Banks) on Jed's truck. We did run a PPE 120hp tune at the track, but it limped his tranny. My tune makes similar power to the PPE 120 but is more streetable and easier on the tranny due to the extra work I put into the torque limited injection quantity tables, or in other words, the tables the ECM refers to when the TCM commands torque managment during a shift, but then again, im an idiot so thats probably common knowledge.

Yes I am saying hes running a stock intake. No hes not running a "K&N" like every other fool who thinks it adds 500hp to his engine. The stock Dmax airbox flows plenty enough and filters much better than any aftermarket intake, save for the AFE Pro-Guard 7 filters.

If not, that is a good way to starve an engine and burn it up.

starve an engine and burn it up? ok. come back when you know how a diesel engine works.

I say stock as in "comparatively" stock. Whats it gonna take to make a gasser 7100 pound crew cab run an 11 second quarter mile? Totally built engine at the least?? I consider it stock because no parts were taken off or added to the engine. Every part on the engine was put there by the factory.

how the FUCK do you hand calculate your fuel milage?? your a fucking sped, how about you take yourself and your dodge and drive off a cliff, the world will be better off.

on another note to the guy who is contemplating a diesel: I would either got with a Ford PS 7.3L, or a chevy duramax. The dodges are crap, except for the engine. Just be careful if you get a duramax LB7, they have issues with injectors but they can make alot of power. goodluck with your search...i just went with chevy because i have a bunch of good resources for maintainance, tech help and aftermarket parts.

Who gives a crap. He does not even know the difference between stock and modified. He also must not know that a Diesel is essentially an air pump and by not having a free flowing intake while adding gobs of fuel will cause a meltdown and make your EGT go through the roof. He sounds like he is about 17 and thinks he is hot shit because he is attending Devry electronics school.

thats what the TURBOCHARGER is for, dumbass.

EGT will raise above the stoichiometric cumbustion point, but only so much, then it will actually cool down because there is "so much" fuel that its not even burned, and it actually will cool the cylinder temp down.

Do yourself a favor and learn about a turbodiesel. Intake dont do shit. Thats what a bigger turbo is for.

Go back to school since they did not teach you anything. You do not even know the physics involved in a Diesel engine. :shaking: Typical kid who thinks that just adding crap to the engine is the way to go instead of designing a system from the intake to the exhaust so the airflow is correct. (and you still insist it is stock):eek:

Wow, you can rebuild a slushbox. no one on pirate can do that. We do not know how to rebuild engines either. :shaking: Your so called skill in modifying the computer is also a joke. What program are you using? That is what is doing the work, not you typing in parameters.

Since someone brought you here to yap about Isuzu max engines, do everyone a favor and try to understand how they work or better yet just leave you fawking noob.

thats what the TURBOCHARGER is for, dumbass.

EGT will raise above the stoichiometric cumbustion point, but only so much, then it will actually cool down because there is "so much" fuel that its not even burned, and it actually will cool the cylinder temp down.

Do yourself a favor and learn about a turbodiesel. Intake dont do shit. Thats what a bigger turbo is for.

Hmm, "Intake don't do shit".... Guess that's why people spend so much time trying to minimize the pressure losses of the aftercooler on any of the "Big 3" diesel pick-ups - look up aftercooler vs intercooler before you open mouth insert foot.

BTW - who did the power balance & sized the turbo for your truck? You?..... Do you know how to read a compressor map or what it tells you? Spend a few months actually working at a place like Garrett Turbocharger and you might learn something.

You know I actually read all of the thread and truly fell dumber for having done it. If you don't know that intake is a crucial part of an air pump (essentially what a diesel is) then you really have a lot to learn. Now I'll dmit that I know very little about the duramax and it is quite possible that the factory intake is very effecient and may not need to be upgraded up to a certain point, but there is a breakover point where more air is needed. Here's an example that you might be able to wrap your simple mind around. Breathe in and out heavily. Now do the same through a straw. Tell me which one makes you pass out first.

After awakening you will come to realize the concept of airflow. On a diesel engine it doesn't matter how big your turbo is if it it going through a 2" intake you'll never be able to move as much as air as someone with a 4" intake

The duramaxes are coming on in power but they are still getting owned at a ton of the events. Their high revving nature gives them an advantage at the track but sled pulling (aka towing) they don't have as much grunt. I can see the duramaxes pulling a head at the track due to the ability to rev more, but I don't see them ever taking over sled pulling.

As for buying one of the big three go drive all of them and pick the one you like there are good reasons for buying all of them.

>>15-16 mixed driving. 18 at 75-80mph highway. 22 at 65mph highway.

06-20-2006, 05:50 PM

I have searched and read some very good threads...but none of them really hit on what I am looking for.

I am looking to buy a new diesel truck; I have always owned Fords and for work trucks I still think they cannot be beat.

In the research I have done something that has been popping up is that the Duramax is getting consistent 23 mpg compared to the Powerstroke varying from 16-21.

I am looking to buy a Daily Driver not something that will be used as a workhorse - I will only be hauling lighter loads and towing a boat on occasion.

4wd is a must as is extended cab

Things I am looking for input with:

-Manual or automatic -- Driving a standard daily does not bother me

-Best fuel economy

-New or used -- with current financing both monthly payments are the same, I am leaning toward new

-configuration -- extended cab is a must; should I go all out and buy a crew cab - long bed vs. short bed (my thoughts are = ext. cab long bed, CC short bed)

---

I will be doing driving in Southeast Kentucky - I just accepted a district executive position with Boy Scouts of America. They are going to provide me with a vehicle allotment of $450-$500 a month. The driving will be in rather mountainous areas but primarily on the highway and back roads to access small towns/communities where Scout Troops are.

Okay, to actually try and answer some of your questions....

Having lived with Extra Cab and/or Quad Cab Dodges for the last 10 years, I would get a crew cab in a heartbeat. The back seat of my truck is gear for gear, tolerable for small children and a prison cell for an adult. My next truck will be a crew cab.

A short bed is the most worthless idea ever on pick-up IMO.

My two Dodge CTDs have been sticks - I really enjoy my 6spd when towing my 36ft Patio Hauler 5th wheel. However, in DD traffic the stick pretty much blows because it shifts so poorly. Given 10 years of 'experience', I'd buy an auto like the Allison in a heartbeat - it would suit my needs better 99% of the time.

I'm gonna call BS on anybody getting 23mpg consistently in any 3/4 ton diesel P/U. On an easy all interstate drive you might get 23mpg if you're lucky and very conservative but don't expect anything better than about 18-19 mpg combined.

New or used is up to you. Depends on the market.

I'd get a crew cab long bed if available. A short bed doesn't make enough of a difference, if any IMO, in manueverability to offset the reduced cargo capacity.

Hmm, "Intake don't do shit".... Guess that's why people spend so much time trying to minimize the pressure losses of the aftercooler on any of the "Big 3" diesel pick-ups
BTW - who did the power balance & sized the turbo for your truck? You?..... Do you know how to read a compressor map or what it tells you? Spend a few months actually working at a place like Garrett Turbocharger and you might learn something.

Brian

as far as I know, none of the big 3 use an aftercooler. At least the Duramax only uses a CAC....if it uses something else than I havent taken a Dmax apart enough.

"minimize the pressure loss of the aftercooler" I think you are babbling off useless BS to try to trip me up because that statement makes no sense at all. The CAC isnt supposed to have any pressure loss unless its broken or has a leaking boot. If anything, yeah, it may drop the pressure a bit only because it lowers the intake charge (note, CHARGE, read: AFTER the turbo, NOTHING to do with intake) temp, and when air temperature is lowerd, pressure drops...but as the pressure drops, the intake charge in turn becomes denser, allowing the engine to intake cooler, denser, more 02 rich air, even if its at less technical "boost"/atmospheric pressure than without a CAC. No, I didnt map out the turbo myself, and I dont claim to know much about mapping the A/R of the compressor and exhaust housings. As I understand it, a map on paper basically shows the useful range of a turbo compressor housing/wheel that a turbo can be used and still be efficent...ie, it shows if you flow more than X amount of air at more than X rate, the turbo will become innefficent, and harm the engines power output more than it will help it. If you spool a turbo more than it was designed for/overspeed it, you are "out of the turbo's map", or at least thats how I understand it. I should know, because I was stupid enough to operate my stock turbo wayyyy the hell out of its map for a long time until it eventually failed. Stock 2005 Dmax LLY turbo is a Garrett AVNT-37, or just a VNT-37 on the earlier 2004.5 Dmax's, the A standing for Advanced (variable nozel turbine). I think the compressor housing A/R is 1.07, I have no idea what the exhaust hosuing is. Stock they make around 24 psi on the Dmax. I was running it at 52 psi of boost. I dont even want to know what the drive pressure or charge temp was at that much boost, it must have been upwards of 100 psi. ~32psi is right on the edge of the map for thsoe turbos. Obviously I dont question why it failed running 52psi for a month. People are like "ohh shit the truck must have hauled ass!!!" no, performance kinda sucked because it was way out of its map and the nuts drive pressure was killing the engine's power output. The turbo I have now I think has too big an exhaust housing. That, and I have fuel delivery problems. Im workign on narrowing it down. As far as blocking off the rail press releif valve etc... I can hardly maintain 19,100psi down the track. This is not letting thr new turbo work to its potential because there isnt enough fuel to provide a dense enough, big enough exhaust charge to "back up" the exhaust and build enough drive pressure to properly spool the turbo. EGT's are much much lower now, Im not even hitting 1525* at the quarter mile mark. With the VVT I would be kissing 2000* because of the drive pressure/inefficency of the VVT. So, my EGT's are low with the new turbo, but its not building the boost I want witht he current fuel I have. The exhaust hosuing I think is slightly too big as I said before, hence the low EGT's, yet not as much boost as I want. But who knows, I just teach myself this stuff as I go along, and as I need the info. Its a slow work in progress because I have to do all the work/testing myself. I dont have endless $$$$ to just hand to a diesel performnce shop and say "here, make it fast"

With your vast tuning knowledge why aren't you working as a consultant for a large company making bank? What type of testing are you doing to validate your table tweaking? Quick ET's are great but they don't make for a reliable tow rig/DD and are only a small part of a very large equation.

For somebody that claims to know so much about diesels I find very difficult to believe you knowingly ran at ~1900F EGTs and 52psi boost for any amount of time.

Long trip, just highway, I see about 18, maybe a bit less, thats with 285's, 7200 pounds. Around town I see 15-16mpg.

Just face facts junior, you got a inferior truck, with a garbage engine and pussified IFS. Go ask mommy if you can trade it in on a real truck when you turn 18.

You win. Our trucks suck. Our engines are garbage. There, I said it, go throw a party that you emerged victorious, and feel good about yourself that show "showed them chebby boys real good".

Alot more than you since you don't even know the physics behind a Diesel. You seem to think you are hot shit because you can rebuild the immitation Allison tranny that chevy uses and you can pull the heads on a IsuzuMax:laughing:

As for Building Diesels ( not just slapping nos, propane and a computer program in it) I have been around a few real engines. You ever gone through a Big cam 4 ? Do you even know what that is? go to most engine shops and they will not even touch it:flipoff2: Oh, I forgot, You just mod by adding crap to a "stock engine"

As for your intake is useless argument, you need to get a physics lesson jr if you do not even know this basic principal.:eek:

and just what do YOU know about modding diesel's?? Ill say it once, Ill say it 1000 times, intake is wasted money on a turbo diesel, I dont know why we are arguing about this.

the Allison isnt just "any slushbox" with a silly governer and TV cable. Its a bit more complicated than that. Go around to any tranny shop. 8 out of 10 of them wont touch an Allison. Same think with a Dmax, its not the same as rebuilding simple SBC smallblock chevy.

program I use for the Dmax is EFILive, ive tuned TBI's in straight hex, but its so much wasted time and effort. Whats the point? All the program does is provide a GUI between you and the hex. Its up to you YOURSELF do modify the hundreds of ECM tables and values. You dont just point and click and enter "I want X amount more hp". Takes time and lots of testing. Ask Jed if the first tune I made for his truck ran perfectly (it flat out sucked). You need to be careful too. Mistype one number in, say, the "injection timing after pilot (D)" table and guess what? You blow your engine, game over.

same thing with tuning the trans too. I make all changes VERY gradually. In the 3-4 clutch hand off (especailly with a built trans) if the trim isnt applied witht he right shift timing, you grenade the trans. -500miliseconds and -530miliseconds is the difference between a firm clean shift (good) and a tie up (bad, very bad).

Say I had a bone stock Duramax, You're a smart fellow, tell me EVERYTHING needed to run, say a 12 second quarter mile...in detail too, you wouldnt want to forget anything, lest you not get enough air intake and blow the engine.

Check and mate numb nutz,

a Big cam 4 is a diesel and a very common one used in commercial applications.My fleet had the 400 version. It is made by a little known company called Cummins. Try Google, it is your friend.

Go back to wherever you crawled out of Troll boy.

You also passively admitted to never building/working on/modding diesels, so there, shut up again. No, I dont know what the fuck a big cam 4 is, all I know is diesels and thats all I care to know about because they are the only engines that concern me. Are we talking about big cam 4's? No we're talking about diesels. Stay on topic dumbass.

and Ill ask you again, tell me how to build up a Duramax right. If you ever so much as think of the word "Banks" ill laugh my ass off.

With your vast tuning knowledge why aren't you working as a consultant for a large company making bank? What type of testing are you doing to validate your table tweaking? Quick ET's are great but they don't make for a reliable tow rig/DD and are only a small part of a very large equation.

For somebody that claims to know so much about diesels I find very difficult to believe you knowingly ran at ~1900F EGTs and 52psi boost for any amount of time.

Brian

my knowledge isnt "vast" by any means...I work with stuff that ive taught myself by real world trial and error. I dont know near enough to work for any "big" tuning company. I just try stuff myself and if it works, great, good for me, if it doesnt work, well then I try something else. I have no former education or background in ANY of this stuff. Testing? haha the most solid testing I can confirm is seat of the pants.:( If it feels fast, Im happy, thats all I care about. On Jeds truck we did it all by SOTP and datalogging with a laptop to check timing and inj pulse width curves, to make sure timing wasnt coming on too soon (bad). But for the most part, tuning a diesel is simple, I dont claim to be some superhero in that department. All it is is fuel and timing. Its pretty fogiving too unlike gasser tuning....if you pay attention to the engine and know what to listen for, it will tell you when you have gone too far....that is unless you make a bonehead move in teh tuning and type in a value that is way out of wack (ie, you accidentally type 200* of timing for some table). As far as towing, thats also by SOTP, and EGT's. If it feels strong and EGT's arent out of control pulling grades, thats fine with me. I completely agree with you that quick ET's dont make for a reliable DD/tow rig, good point. :) Back when I used factory tuning, a quick truck at the track meant a lot of sacrifces around town. PPE Hot Xcellerator, big power, ran fast at the track, but the damn thing wasnt streetable for beans. Way too touchy, you cant even pull away from a stop smoothly without surging and bucking due to the really sensitive throttle. And it smoked a LOT. Forget towing with it, EGT's would be nuts. A PPE/Van Aaken stack could make an LLY Dmax run 12's, but it did run hot and this took its toll on the turbo....the LB7 turbos have proven to be much more robust under modding and racing.

EGT's I was running, Yes......I was a dumbass for doing that, ill be the first person to admit it.:D EGT's were near 2000* passing thru the 1/4 mile, but I would never "sustain" that on the street. Getting onto the highway, I could do 1600*, but I was concious of this and would back out till EGT's stabilized. 52psi of boost...........I didnt have a "real" boost guage back then, I simply read it off the data bus from the MAP sensor. (take MAP sensor reading, subtract 14 or whatever the current atmospheric pressure was) I was running a custom tune that someone helped me with (im running the same guys tunes now, he doesnt work for some big company and has no previous knowlege, he just uses EFILive and has an amazing knack for it, My own tunes I could never get to run faster than high 13's at the track simply because they werent good enough, so I sought him out for help) stacked with an Edge Juice module. I had an early version of the Edge (v1.0) that capped/intercepted/modded the signal that the ECM could see from the MAP sensor. So basically I was running 52psi even tho according to the MAP sensor I was only running 28-30. Didnt have the money at the time for a real boost gauge. Finalyl saved up enough $$ bought one, and crapped my pants when I saw how much boost I was running. Maybe a week or so later I fired the truck up and the turbo started to whine and howl like wind whistling thru a cave in a cheesy scary movie.:shaking: That was that....turbo was fried...close to 1/8" of radial shaft play and 1/16" or so of axial shaft play.:(

Hey Ben, SuperDiesel has a new injector pump to fix that rail pressure problem. It'll run 29,000psi to compensate for bigger sticks which he is also going to have soon. He also told me that the LBZ pump at least on LB7's will make more pressure.

IIRC a Big Cam 4 is a 8.3 CTD used in trucks FYI.

The intake means very little on a D-Max and isn't worth your $$$$ as stated. I don't know why people argue with research :shaking: . An A5000 or Twins make a hell of a lot of air. The intake doesn't help much if any. Been there done that,so has Ben.

30-32psi max safe for a D-Max. I regularly hit 30psi on mine and haven't had any problems.

Which is still a long way from 52 psi........

wow, you guys know how to warp comments into what you want them to say...for the ignorant, maybe you should STFU, or learn something from us (the "light duty" guys) we are not saying that our trucks are the best, we are just trying to show you that there is another "viable" option from the praised cummins, and or PSD. I will admit that the other options are great trucks (but, not a fan of that thing wrapped around the amazing cummins:shaking: ). Like many have mentioned, all it takes is to test drive each of the options. But, as you can tell, all of these trucks have been proven to exceed the expectations of most the owners...and that is where there will be no real good answer to which is better...no man will admit that their truck is inferior to another.

Ben,
I suspect you might have addressed the issue already but if you haven't then you really need to look at a properly matched turbocharger. Running the stock turbo at 52 psi is well outside it's optimum parameters Stock (and I mean literally stock) boost is limited to ~20-25psi on the DMax, correct?

Brian

ohhh yes 52psi is way out of the stock turbo's design range. Yeah stock psi is around 24 or so. On the Dmax's the VVT's seem to just get innefficent and suck above 32psi, and on the LB7's that had an IHI wastegated turbo, they will shotgun above 32. So the IHI's work great then all of a sudden go out with a bang, while the VVT's just start to howl at you and not build boost as fast. The turbo I put on there when my stock one blew is a Borg-warner Schwitzer S300 derrivative, I honestly have no idea what the A/R is of either housing, it works well on the LB7's and those guys are seeing lots of success with it (first gen dmax) because their injectors can deliver more fuel than the LLY's and spool the turbo much higher so its in its effective range (45psi).....and on top of that the LLY's have other "issues" too that prevent them from being as easy to hotrod. I was the first guy to ever install one on an LLY (another guy did a custom setup on his LLY at the exact same time), so I was going into uncharted territory...I had to do custom stuff and extra work to make it fit (cause it was designed as an LB7 aftermarket turbo), which wasnt fun either... Even if I knew the A/R I wouldnt know what to do with it, or if its right for my engine because im not an engineer and dont know ANY of the complicated math/physics behind the more complex sides of turbos, or how to map one correctly. With my truck, I just cant get enough fuel to spool it more than 36psi. I think I just need to figure out my fuel issues and as I get more fuel, the turbo's efficency will fall into place and it will work much better.

If I had more money I would have liked to have gone for the big boy....the ATS Aurora 5000. I have no idea what kind of turbo it is, but the friggin thing is a monstor. 60psi easilly, no wastegate.....but because theres no wastegate you need headstuds as well, which is even more $$$:(

06-20-2006, 07:23 PM

as far as I know, none of the big 3 use an aftercooler. At least the Duramax only uses a CAC....if it uses something else than I havent taken a Dmax apart enough.

"minimize the pressure loss of the aftercooler" I think you are babbling off useless BS to try to trip me up because that statement makes no sense at all. The CAC isnt supposed to have any pressure loss unless its broken or has a leaking boot. If anything, yeah, it may drop the pressure a bit only because it lowers the intake charge (note, CHARGE, read: AFTER the turbo, NOTHING to do with intake) temp, and when air temperature is lowerd, pressure drops...but as the pressure drops, the intake charge in turn becomes denser, allowing the engine to intake cooler, denser, more 02 rich air, even if its at less technical "boost"/atmospheric pressure than without a CAC. No, I didnt map out the turbo myself, and I dont claim to know much about mapping the A/R of the compressor and exhaust housings. As I understand it, a map on paper basically shows the useful range of a turbo compressor housing/wheel that a turbo can be used and still be efficent...ie, it shows if you flow more than X amount of air at more than X rate, the turbo will become innefficent, and harm the engines power output more than it will help it. If you spool a turbo more than it was designed for/overspeed it, you are "out of the turbo's map", or at least thats how I understand it. I should know, because I was stupid enough to operate my stock turbo wayyyy the hell out of its map for a long time until it eventually failed. Stock 2005 Dmax LLY turbo is a Garrett AVNT-37, or just a VNT-37 on the earlier 2004.5 Dmax's, the A standing for Advanced (variable nozel turbine). I think the compressor housing A/R is 1.07, I have no idea what the exhaust hosuing is. Stock they make around 24 psi on the Dmax. I was running it at 52 psi of boost. I dont even want to know what the drive pressure or charge temp was at that much boost, it must have been upwards of 100 psi. ~32psi is right on the edge of the map for thsoe turbos. Obviously I dont question why it failed running 52psi for a month. People are like "ohh shit the truck must have hauled ass!!!" no, performance kinda sucked because it was way out of its map and the nuts drive pressure was killing the engine's power output. The turbo I have now I think has too big an exhaust housing. That, and I have fuel delivery problems. Im workign on narrowing it down. As far as blocking off the rail press releif valve etc... I can hardly maintain 19,100psi down the track. This is not letting thr new turbo work to its potential because there isnt enough fuel to provide
