BTW, ignore what I posted above about my concerns with the Dynapack AWD dyno. A Dynapack employee explained the system a while back:
Quoting: "The system doesn't mechanically "lock" the wheels, it continuously monitors the wheelspeed and keeps it within 1 or 2 rpm of each other - which isn't anywhere near enough to heat any of the differentials - the car sees a wider variation than this when being driven. This allows us to adjust load to suit the needs of each individual corner for the specific reason of NOT loading parts in a harmful way. It also allows us to measure individual torque split on each corner - something useful in determining if a differential is going bad and catching it before something bad happens."
So maybe it really DOES mimick real world driving conditions. But I still don't know what losses are normal for a 993 C4 on a Dynapack dyne. Anyone know?
