Yeah, the twin turbos are mainly used to meet emissions but they also seem to be a big part of ford's marketing campaign. Unfortunatly I think those turbos and injectors are going to be the root of most of their problems, but time will tell.

 

The torque is impressive! However, the 6.0L had higher hp numbers.
And to compare it to the 2006 Duramax LBZ they seam to be close on tq, (I have seen a few dyno charts with the LBZ putting down about 610 ft lb tq. stock) But the LBZ puts down about 310-320 rwhp.

But unless the two trucks are tested on the same dyno, on the same day, by the same operator, in the same conditions, we don't know which one puts down better numbers.

 

Sorry to say but that is one fugly looking grill and headlight design on that new truck. Where is GMC and Ford going with this? Strange. Keep it simple.

 

Does any one know what a stcok Dodge Cummins puts out?

 

Bone stock, my little 305/555 Cummins layed down 267hp/501tq. so I'm not theat impressed either with the hp #'s anyway especially when compared to what its rating is listed at. But the tourqe, all I say is wow!

 

that torque number is BS. Here is my reasoning why.

Its on a Dynojet...we know how well those work for diesels

you can hear the truck shifting during the run. Dynojets are notourious for giving huge "shift spikes" in the curve.

Its an auto; there is NO WAY it only lost 3% in the drive train. I doubt Ford is underrating the truck. If they were underrating things that much then why would they brag about the "torque starting at 2000 RPM!!!!!!"

WHERES THE DYNO SHEET?????

 

IMHO, it doesn't matter to me what the final RWHP and torque are.... My stock CTD has enough grunt to pull all the hay and horses that I will ever pull. It will do it without ever maxing out the truck. To me, anything past that is just bonus. I bought a CTD for reliability, durability, and simplicity of maintenance. I plan on putting 350,000 on this one just as I did the last one. Hopefully it will be as problem free as the last one.!!!

 

The noise was the tires on the rollers Iker.Probably running an aggressive tread pattern.Not bad numbers fora stock truck though but is still a FORD

 

My thoughts exactly.. Drive train loss doesn't pick favorites for Hp vs torque. 3% loss is total BS...Try 20%...

 

When I drove an 08 6.4L it seemed about as powerful as the 6.0L trucks but with better throttle response... Compared to the 6.7L Cummins and the LBM 365hp Dmax, I thought the 6.4L felt underpowered.

I'd think the torque looks unreasonable, like someone said a spike or just a wacky Dynojet reading. I should have just paid the $50 and rolled the trucks over to the Mustang dyno I usually use and get some numbers on them. Seat of the pants told me the 6.7L makes the most torque followed closely by the 6.6 Dmax and the 6.4 Ford noticeably less.

 

IMO those are great numbers for stock especially an auto. My ex put down 327hp and like 627lb ft running her BDPP on 90hp with her '04.5 auto. On that note I think they are doing pretty dang good power wise with it being stock.

 

That's not a Dynojet, that is a Dyno Dynamics load dyno. More like a Mustang than a Dynojet. magnetic eddy retarder.

The same kind Piers used when he ran PDR.

 

Who said it was stock..Looks like someone is boasting an add on component to me. Whats DieselPower

 

It's a magazine...

 

That dyno is giving corrected numbers for flywheel - a common problem you see in dyno testing.

David Kennedy (diesel power magazine editor) is bringing the same truck over to my shop tomorrow morning to have it dyno'd on our Mustang chassis dyno. No inflated numbers, it'll give actual SAE HP and torque from the wheels....

We bought extra fire extinguishers for the occasion,
