I am not that experimented as Ian or mr.Finch but what I have seen over the years is that a WRC YB engine produced around 350bhp, but for torque I have never seen really any real figure. Between 650 and 750Nm depending of age and tuner.
Recent WRC cars are around the 1000Nm barrier. Spoken to a Bozian engineer 2 years ago (307 WRC) he told me the 307 had more than 1000Nm of torque. Basically I have never seen the real figures, but I assume the modern WRC cars are quite near the 1000 barrier.
The old Octavia was doing between 600 and 750Nm between versions, and this was an old car...
