Perhaps you can answer some questions I have regarding torque split
The torsen ratio for the UrS is 2:1, but I have read that the max torque split is 75/25%. This calculates to a 3:1 ratio.
Am I missing something in how the torque split is calculated from the ratio?
The Stasis website states that their 4:1 unit can send up to 88% of the torque to the front or rear. A 4:1 ratio should max out at 80/20 by my calculation.
I agree that a higher ratio torsen center diff is of little use to most street and even track cars. The only way you would see any benifit is if you have enough power to spin the front wheels on corner exit when the front inside tire is unloaded.
