I was just wondering what is the normal torque split between front and rear under normal driving conditions and what is the maximum torque that can be sent to each wheel or the rear or front.
Torque split under normal driving conditions is almost zero but the rear engages slightly when pulling away to prevent wheelspin. If wheelspin is then detected it will ramp up the rear engagement a little more. Not sure what the maximum stock engagement is but it's definitely set so as to reduce the Haldex maintenance schedule and not for performance
You can have a look here to determine split. Looks like best case split for stock is 70% Front, 30% rear but even with the Comp controller mode it looks like the max best case split is about 60% Front, 40% rear:
The haldex system consists of a hydraulic clutch that locks from 0 to 100% but it's inline with the propshaft to the rear diff. Torque from the transfer box is split 50/50 front and rear of the car, so when the haldex is disengaged, all power is delivered to the front (the propshaft still spins but no torque goes beyond the clutch). When the haldex is fully engaged, the 50% available from the propshaft is fed to the rear wheels also, so the total power is split 50/50. So, as the haldex engages, power distribution changes from 100/0 to 50/50 front to rear.
The system response is active and not fully coupled at all times. See self study programme 206 for a full description, but fundamentally the system is for acceleration.
Getting more tempted to look at this, but don't drive my car much. 15 miles this week and next week prob 0
