AWD Transfer case

[patrickk1]

Syclone, Typhoon, Astro, Safari, and Bravada ALL share the same transfercase, the Borg-Warner 1372/4472. The only difference is the spline count on input or output shafts on earlier vs. later models. The torque is split 35 front/65 rear. From what i have researched they are rated at 1100ftlbs torque. Keep in mind that this torque rating and the one above is rated at the output of the transmission. 1100 ft-lbs isn't all that high. A 400 ft-lb motor and a 4L60e (3.06:1 1st gear) and you're already at 1225 ft-lbs. Multiply that by torque convertor torque multiplication factor (assume 1.9) and you get 2325 ft-lbs keeping in mind that max torque multiplication would only occur for a momentary period in time. There are Sy's and Ty's running 9's and 10's in the quarter on the stock transfercase (not the stock trannies though).
