Post Duty Solenoid C......Expreiment?

I think its a about time that we start looking for a new mod. The tourqe split in our cars AWD system is controlled by the duty solenoid C, and is set to a 91/10 front bias for all reasons apparent. It makes for a nice, smooth, easy driving car. The tourqe split on a porsche is 40/60....set just shy of cener bias for the optimum split. Our cars are capable of a 50/50 locked if you remove all the resistance to duty solenoid C. This would make for a nice split with tons less transfer loss due to having the Diff's locked. The real question is will that effect the RWD clutch plate in the trannsmission. That is usually the first thing to give out in a failing tranny and we certainly would want to detonate it. The diff can sure take it, the rearend diff is from a 300zx, and is fully proven to 600+ hp in many occasions. Well, if anyone has a parts manual see if you can locate the duty solenoid C resistor so we know, im checking wiht the dealership tommorow if i have time and see what their thoughts on it are.
later,

Don't confuse the 300ZX (280ZX shape, but boxy with pop-up headlights) with the 300Z (AKA the jelly bean)

Power not sent through the center and rear differentials is power not lost in the center and rear differentials.The advantage of the 90/10 split is increased efficiency.

If it is a touch of oversteer you are after, perhaps you will find changing the rear sway bar to one of a thicker diameter to be the cure.

Increasing the air pressure in your tires will also have a most noticeable effect on the handling charactristic of your SVX-- IIRC stock settings are supposed to be 30ft-lbs 29ft-lbs, Me and my car-loving pals run at 40ft-lbs 40ft-lbs. The ride is very harsh, but the difference in the corners is magnificent!!!

Hey Phil, nice try, trying to stur things up on the "I". I just have one question, won't a 50/50 split cause binding in corners?

IMHO a 50/50 split will cause binding in corners on 4EAT Subarus. If your Subaru has a 5MT the split is 50/50 by default.

50/50 in a 4EAT is OK when you are going in a straight line or the surface is slippery.

I was thinking more along the lines of running a line to the front toggle on and off....to use for drag racing not in town driving or road racing. The 50/50 split would give a very nice luanch off the line, and having a toggle switch would allow us to simply turn the car off and switch it back with no problem(apparent atleast). I dont drive around town with the resistor mod either, only when i mean buisness.
