You say Potentiometer...I say Variable Center Differential

I got to thinking about this the other day and asked my electrical guru about it. I was thinking about a RWD SVX after reading a post title here. Now, I have been thinking about it, and what my wiring guy said, and he thinks it is possible to tap into a certain wire on the transmission and splice, solder and connect it to a volume knob of sorts. Is this remotely possible. I have heard of people creating their own Power Mode Toggle setup, so I figured why not a makeshift VCD. Any thoughts.

Only reason I would even consider this is because every now and again I feel the need to drift. Also would not be a bad idea for the track either.

There have been a couple of threads on this not variable but either on or off. and I don't think you can go any further than 50/50 rearward on the US spec cars 90/10 forward I think is the other xtreme. Somebody with a tech book or something that could indicate which wire and let you at it from there.

As I understand it, the torque split is not dependant on the voltage applied to the solenoid.

The solenoid is always in one of two states: open or closed. The TCU applies rapid 12volt pulses to the wire, causing the solenoid to constantly chatter between open and closed. The torque split depends on the ratio of time-open to time-closed. The higher the ratio, the higher the oil pressure applied to the transfer clutch.

Varying the voltage with a potentiometer will not serve the purpose. You would need to build a pulse generator and vary the frequency of the pulses in order to change the torque split.

Or you could just let Subaru's superb AWD system handle it all for you.

As Thundering02 said, on a USDM SVX you can only vary the split between 90:10 and 50:50 (front:rear), so RWD is out of the question without some serious modification to the transmission.

Phil's right - a potentiometer wouldn't really work the way you want it to.

As for making the car RWD, I don't think that would actually be that difficult to do. The components are all there, they're just not meant to be used that way and likely wouldn't last.

Didn't somebody once do a RWD conversion by removing the front driveshafts and weld the plates of the transfer clutch together?

A rather permanent way of halving the amount of grip and ruining the handling.
