I'm not saddened at all by Ford. They're in complete control of what they put out there. They've been under the impression that people will keep coming back regardless of what they produce.

Guess what? They won't. I sure didn't

I dont buy the accellerations numbers. The only LBZ/LMM dmax that will run 14's stock off the lot is a regular cab.

and the other thing that doesnt add up, for all intents and purposes the ctd and dmax made the same hp and torque to the wheels, and ran pretty close to the same 1/4 time...but the ctd weighed 500 pounds more...so what gives? I have yet to hear of a stock 6.4 psd break into the 15's too....

"big three comparisons", no matter who they are done by, are stupid If you ask me. Its 25% determined by the numbers that that magazine tested on that day, at that elevation, temp, baro press, weight, fuel level, etc..... the other 75% is the oppinion of what, 5 journalists who call themselves "true knowledgable diesel enthusiasts".

JMO..

How did they manage to get a 71XX # CTD Ram QC/LB?

Aren't new Megas ~8200# off the showroom floor?

Was it 2WD?

the weight seems to be pretty close IMO as far as the Dodge is concerned. I will say im pretty confused about the FORDS weight though. I have driven all the 3 quite a few times, and i believe that the finding are pretty realistic to what i have seen. Im/was a diehard GM fan, but their recent ugly body style change forced me to test drive the new 6.7 before buying, and im very glad i did. I will say that i absolutely love this truck more everytime i drive it.

Supposedly my old truck is in the Dec 2007 issue of Diesel World. My sister's fiance called me up and told me he saw my truck in it. Should be under reader's rigs, they took some pics and got my info when i was at ATS Truck Fest. I couldnt find the mag here in town, i'll pick it up in a diff town tomorrow when i head to work.

And the Dodge is doing it with only 6 cylinders.

The GM ran 5 tenths quicker than the Ram... thats right on for a truck that weighs 500lbs more but makes the same power

Why not hook them all up to a 10,000 lb load and let them pull a 6% grade and see who gets to the top first? 0-60 is fine and dandy I guess but the best motor in my book is the one that pulls grades fastest with the least amount of downshifting.

Call me a troll if you want to, but I see this statement a lot and really dont understand it. The truck that has the most power and is the fastest 0-60 will also be the fastest towing a load up a hill too, am I wrong??

Or does some unknown load-triggered power reserve kick in on the slower truck, helping it to haul loads better?

And as far as the downshifting thing, who cares? The CTD undoubtedtly makes way more low end torque than both the dmax and psd, but If I can tow a load up a hill downshifting and taching the engine out faster than a CTD can lugging it in a low gear, what difference does it make? I just want to get to the top of the hill the fastest way possible when I tow a large load.

just my oppinion

I'd be interested in repair history at 100K miles and number of dealer trips beyond normal maintenance.

Yup i think you are wrong. Take a 700HP honda civic and hook it up to a 10,000lb load and see what happens.



There are a lot more things to consider when pulling loads then JUST power.
You have to take tire size, final gear ratios, weight (like you stated), and how efficiently the transmission shifts and transfers power during shifts. There is no doubt to anyone that the allison is an awesome tranny, but in my opinion it is really smoot and doesnt shift too firm, which when loaded down, a more firm shifting transmission can transfer the power more effectively. Its kinda like powershifting or double clutching a manual tranny VS granny shifting.

While the Hp curves come into play a lot more in just drag racing, the TQ curves come into play a lot more when pulling.

I think that the duramax would probably pull a little better at high speeds then the cummins just b/c of one factor, the duramax can rev a little bit higher so if both trucks were pulling at the same speed, say 75MPH, the duramax could probably down shift to 4th gear, while the cummins would be limited to downshift to 5th (dont know for sure at this speed, just for example). The Duramax would have the advantage b/c it would have lower final gear ratio and would still be making good power, but no one really needs to be pulling that heavy of a load at 75mph and then trying to race some one else anyways.

But IMO the Cummins has the advantage at all other speeds b/c lets face it, both trucks have the power to go through the gears with ease when pulling loads. The cummins is going to go through the gears quicker b/c it shifts sooner and will be in higher gears faster. So long as the truck has the power to pull through the gears with a load then it will be a good advantage, but if not then i could see the opposite being the truth as far as GAINING high speed is concerned. But i think it takes a lot more weight then any of the chassis are even capable of to reach that point so it is nothing to worry about.

HP is how fast you hit the wall, TQ is how far you take the wall with you.

Anyone else seen Ford's recent "Big Dog Daddy" commercial on TV where they claim to have more power than a Dodge Cummins? Where do they get off saying that, and how come Chrysler hasn't sued their butts off for it?

Right or wrong, that kind of stuff sticks in people's heads when they're making buying decisions.
