Can you dyno a C4?

[indigowhale]

If so, how do you turn off the AWD or does it just stay off in the front? Someone with experience, let me know.

TIA.

There are all wheel drive dynos. I've got no experience with AWD Porsches specifically, but the guys who tune Audis (quattro) usually use them. That said, I think it is possible to disable the electronics that activate the AWD on a 964 (993 C4 and later use a viscous coupling rather than electronics to actuate the AWD).

on an AWD dyno yes

or

physically disconnect the front drive shaft.
