Your right those are very fast cars try the carrera Gt, that will be the fastest car you have ever drove

 

Who is on the inside for you? Can you verify this?

 

what i want to know is if these things are putting out 400 hp and 700 tq is the rest of the drivetrain going to be able to handle it for 150,000 + miles towing day in day out? I hope they beef the rest of the truck up to go with it and not just build a huge engine to say they have the best.

 

The 700lbs of tq will be great if its at a low rpm. The 6.0s tq is at too high rpm (2200rpms) when pulling large loads (20-30k). Ford had better not have problems with the 6.4 and it better be able to pull a lot better than the 6.0. I have a 05 350 cab and chassis dual wheel with flatbed dump. It has a 6.0 4x4 with 6speed manual and 4.10 rearend. Brother in law has 05 Dodge 3500 with 610Cummins 6speed manual and 3.73 rearend. With both of us pulling 32ft livestock trailers loaded at 25k that Dodge (Cummins) will walk off and leave me. I don't know what the tq curve is on the 610 cummins, but I do know first hand it will pull an unreal amount of weight at 1000 rpms. If any of you want to know what a one ton diseal truck will do in the real world go to your local stockyard and talk to someone who pulls large goosenecks everyday for a living. Three years ago there were more fords at stockyards and at the rodeo than Chevy and Dodge Combined, but since ford went to the 6.0 there are more Dodges than anything. This is sad because all ford would have to do is come out with a diseal with great low end tq. If ford put a cumminns in it, Chevy and Dodge would go bankrupt. I say this because Ford easily has the best truck, it just needs more tq on the lowend.

 

Would over 450 ft-lbs (at the wheels, not crank) coming online by 1500 rpm be sufficient?

It can be done on the present 6.0 easily when calibrated to do so.

 

Amen.
Well put.
I think the cummins torque is more useable than my 7.3, too. My uncle can pull his hill in 4th (direct), I have to pull it in 3rd. His is a 5 speed dodge, mine is a 6 speed 7.3. Both are supposed to have the same hp (235 hp) & very similar torque (505-525). I think his has a lot more torque than it is rated at, or somehow it is just a lot more useable (if that makes sense).

 

This may be possible, but I have the SCT 1704A on tow safe and it helped, but for the most part it follows the stock torque curve. The SCT bumps up the whole curve at the same amount. It dosn't really boost the lowend. Besides most of us pulling for a living don't want to spend money on chips, gauges, intakes, exhaust, etc. After buying the truck you have already spent 35-40K. These also cause warrenty problems, especially if you breakdown away from home and have to take the truck to a dealer other than the one you bought the truck from.

 

What? That doesn't make any sense. My old '96 pulls in 5th (overdrive) quite well, and i only need to downshift on steep hills to 4th. After the chip, and exhaust/intake work done, my torque curve rises to within 20 ft/lbs of my peak torque at 1400 RPM, the peaks quickly, and carries it all the way through the useable RPM range. Almost table top flat. I wouldn't trade the 7.3L for a Cummins ever. I love it too much.

 

i dont see how the HP will be high. just seems like they are going to have to bugger it up too much with the emissions. i think its the fanboys that are looking and hoping for the stars when the really should be looking at the moon.

 

Toyota has announced their goal (official or no) to be 390 hp and 700 tq. I imagine Fords target SHOULD be a little higher.
