Performance engines are modified to produce more horsepower and torque and it is essential to know what the peak torque or your engine is and to match the stall speed ratio of the torque converter with the engines power curve. Torque the cover to 30 ft/lbs and the brake rod to 120-180 In/lbs (use blue threadlocker). The basic function of torque converters is to multiply torque so as to cope up with the reducing rotational speeds. Tail Shaft Yokes All the same. I see in the report that I am not the only driver having problems. Factory torque converters utilize around 2,000 to 2,200 rpm stall in most diesels, and they're that way for a reason, as most factory ¾-ton pickup-sized engines spin about 3,000 to 3,500 rpm and. For example, if a motor has 400lb/ft (542Nm) of torque and stalls a particular converter at 3000rpm, K = 3000/sqrt {torque} = 150.
