Can anyone tell me how to compute the maximum allowable torque for a 4-40 helicoil (.112 nominal length) in 6061-t6 aluminum?

i believe the 48in oz. given is the locking torque that the locking feature of the helicoil exerts on the inserted screw. (you'll notice that this number decreases with the number of insertions due to the fact the locking feature is spring-like and wears.
