The crank still turns in etorque modeI'm not familiar with the e-torque system. Does it shut the engine off when in the hybrid mode? If so, you won't have the hydraulic pump running on a PSC (engine driven pump) system.
Are you looking to add the boost cylinders on the tierod?I'm thinking it would work, but would require some additional finagling to get a belt driven steering pump onto a etorque.
