Disagree with tranny argument there. Torque is spread over 4 wheels and two diffs so it should be able to handle more than XR6T. ← Yes but when allot of power starts to be produced via mods allot more stress is put on the gearbox. For example when taking off on full throttle a rwd car will spin the wheels which in turn puts less strain on the driveline cause the wheels have no traction the same setup but in a 4wd car puts the full stress of that take off on the driveline for allot longer because it is less likely to spin the wheels and put the full strain of 300rwkw on the gearbox for a longer period of time because the wheels aren’t spinning.
