Where does this number come from? What cars, what track, etc.? Not being negative, but I would actually like to see the results. If it is true, then I too would probably jump on the ACD bandwagon.

Also what shocks would you use in your own race car?

 

I'll trade ya.

 

The hardware is all good, stronger than all pervious models. The only real issue has been that when used in rally applications with more power than Group N cars(like open class evos), in this situation if the driver has altered the ACD maps, and programed their own software stragity without regard to duty cycle of the electric motor running the hydraulic pump, it will overheat and sieze the elec motor. There are upgraded electric motors available however this is only a issue on some drivers due to the way the want the centerdiff to act, and is not legal for Group N cars. Multipule cycles from fully open to fully closed in short order will over work the motor driving the hydraulic pump.

In most cases we will not need to worry about it. Just be super **** about maintainance and bleeding it correctly.


Tarmac numbers come from everywhere. Just start looking into companies that sell ACD controllers and ask professional rally drivers whether it be tarmac or gravel. The looser the surface and the tighter the road the more it helps. You can pay big bucks to get a guy to calibrate your ACD. I imagine a super fast track with no chance of rain or mid to slow corners would be questionable. But slow to mid speed stuff(like rally or street curcits) for sure.

Quaife are for mild FWD cars. Any real power and they are useless, anyone who tells you otherwise has obviously never tried the two back to back(plate VS torsen), or is trying to sell you product. The KAAZ plate diff works very well(and is cheaper), has tunable features, and works when one wheel is off the ground unlike the quaife.

Drag racers may benefit from ACD, but it's slightly heavier than V/C, and it's more complicated, maybe you should use a ralliart HD V/C. But the ACD can be modded, you can install a elec box that with a push of a button takes the ACD out of Auto, and make it infinitely adjustable with a dashboard dial. You can adjust lock from fully open, to fully closed. I imagine this could be used to tune the launch.

Kewl info....reading with great interest.

Where can I source, say a nice KAAZ plate diff. for the USDM EVO8?

Where also, can I get a 'stronger' center diff for the USDM EVO8?

Thanks,
