Subaru say not to do it.

When you run the car on he road with the fuse in, the front wheels drive the back wheels, through the road. This meens that both halfs of the transfer clutch rotate at the same speed.

When running the car on a two wheel dyno, only the front wheels are turning the backs are still, this meens that the transfer clutch has one side running at full bore and the other side is stopped. This will cause a large amount of heat and wear, that the clutch was not designed to have.

I agree with Pockets drive it on the road the dyno wont pick up the things you will on the road, Check the way it engages 2nd gear for slipping band, other wise that model should not have problems.

ChrisG just wants you to do it because he wont do it to his

Harvey.

This is my understanding as well, and is also why 4wd vehicles are expempt from running on 2wd emmision dynos, just have to pass the sniffer.
