6.4L tq vs 6.4L Maxforce 7 in the International trucks

It is funny the 6.4L Maxforce in the int. trucks has a peak tq rating at 1400RPM’s vs. the 6.4l tt in the super duty at 2000RPM’s. This tells me that ford chooses to keep max tq at close to 2000rpm’s for drive train durability or for better performance.

Yes, they did that on the 6.0/VT365 also. It leads many to falsely believe that the peak torque is at 2,000 becuase its a V8 and incapable of producing low end torque similar or better than an inline engine.

duramaximizer is new and has a neutral reputation at this point.
I read somewhere that the 6.4 maxxforce only uses 1 turbo also. Anyone got the info on that?

It is a trade off and for the consumer market, everone thinks they need 300+hp in a truck. But in work applications, torque seems to be a lot more important. Witness the high torque low hp formula in all heavy truck and tractor applications.

As for your drivetrain durability point- not so much an issue. Engine manufactures have been limiting torque in lower gears for just that reason for years and maping higher torque in higher gears. So, in theory, they could map around crazy high torque numbers by limiting output in certain ratios.

It would be realy great if they would let the customer map thier own torque and HP curves according to each persons needs, or at least let you choose from a few?

Isn't that what the chips or programmers are supposed to do? I don't know as I've never had one before. If I remember right, on some systems you can choose different levels of power, shift points, etc.
