No. All of the AWD components still spin, so there's no real advantage.

PLUS, the AWD fuse is a temporary fix ONLY. It is not to be used continuously.

It's not just the FWD solenoid, it's the AWD solenoid being locked open. Continiously running at 100% duty cycle will burn out that solenoid. I think the appropriate result of that is Torque Bind as Duty Solenoid C no longer responds and simply remains at 0% Duty Cycle, effectively locking the center "differential".

I don't know a ton about Automatics, so someone correct me if I'm wrong about that. But I do know it's not good to roll in FWD for too long.

Only the automatics can. Not the Manuals.

Get a flat on the front, swap a rear wheel to the front and put the spare on the rear. Then install the FWD fuse and drive to a tire shop.

That's the procedure for automatics, IIRC.

I never thought about using the FWD fuse on the dyno, i just figured i would have to search far and wide for an AWD dyno when the time finally came. Anyways anyone have any experience/opinions on possibly using the FWD fuse for dyno runs?

You don't have AWD Dyno's out there? Wow. I'm spoiled. There must be a dozen AWD Dynos within 20 miles of my house, 3 within pushing distance of the shop.

As far as I can make it from the transmission manual, fitting the FWD fuse puts the transfer duty solenoid at 0% so that no line pressure is supplied to the center clutch so leaving it fully open (no rear drive), so installing the fuse results in the lowest (none at all) wear of that solenoid.

EVEN IF it were at 100% then it would be on continuously with no movement, I'm pretty sure Subaru wouldn't supply a system for burning it out if it were likely to happen!

A little knowledge is a dangerous thing!

Duty-C goes to 100% with the fuse inline, not 0%.

That means that the solenoid designed NOT to operate at 100% duty... is.

The solenoid isn't really the concern. What IS a concern is the additional heat generated with wheel spin within the clutchpack. You can weld the plates together from the added heat.
