I have a car with a switchable transfercase that will allow me to choose between running FWD and AWD. I'll be putting the car on the dyno shortly, and I was just theorizing drivetrain output differences. Obviously HP numbers should drop roughly 15% because of the increase of mass on the drivetrain going to AWD, but I was wondering how torque output would be affected? I cannot see rotational force being affected greatly? Though it must since HP will be down roughly 10-15%, torque should be the same right?
