Torque.... how much is needed for a pickup ?
I see we have somewhere in the vicinity of 750- 800 ft. lbs. of torque in 2014 pickups, with turbo diesel engines. A number of years ago 450-500 ft. lbs of torque was considered a torquemeister. ...

I remember the 1986 F-250 6.9L diesel, without a turbo, and Ford had to limit the torque to only a few hundred foot pounds, due to the transmission not holding up to much more power. Aftermarket turbochargers added a LOT of power, but you could only use it with a manual transmission, and even that did not hold up well due to the transmission limits. Back in 1986, the 460 gas engine was the big dog trailer puller. The deisel was not king of the pickup hill just yet. By 1993, with the factory turbo on the new 7.3L engine, and improved C6 as well as a new 4 speed automatic, the diesel was making more power, and the transmission holding up to that factory power rating. Still aftermarket "Improvements" in HP and torque would be able to put damaging horsepower through that transmission, and they did not tend to last more than 100,000 to 135,0000 miles.
Transmissions have been improved a lot, and now can handle 600+ foot pounds of torque.
