Benwantland ... so it's 440 ft-lbs at 1000 rpm, eh? I got lured into a much higher (500) estimate because the dodge-ladies kept crying when I guessed it at 450. If you calculate backwards from the the PSD is doing, you'd need 553 out of the Cummins at just off idle (1000 rpm) to match the PSD anyway. Of course .... it'd be a cold day in Heck before you get that. (ssshhhh. The dodge ladies think their torque curve is so flat that it's just under 600 ft-lbs at idle. Let's don't tell them, cause they get all agitated and stirred up).
