A 3.8l twin turbo V6 at 550hp should be able to produce over 1200nm....
No.
1200nm of torque at ~3250rpm is 550hp.
And there is no way you can make 800+ ft-lbs of torque from a 3.8L on pump gas without things being ridiculously trick, to the point of it being completely impractical.
my F6 downstairs has a single turbo blowing a 4.0l I6 and it only makes 480hp at the wheels but 1200nm.
Again, your torque number is grossly inflated. I can believe an F6 making a good bit more torque than horsepower but not that much more, particularly considering (again) the internal stresses caused by that type of torque-to-displacement ratio and the fact that it'd have to run out of breath at around 2800rpm to only make 480hp.
Maybe if you were talking about actual diesels, but even then you're saying these <5L 6cyls should be capable of reliably making more torque than any of the HD pickups currently on the market stateside...
