what does this pulley do ?
I maybe missing something simple here... but on this rs500 btcc, there is an extra pulley just above and to the centre of the cam pulleys. Just wondered what it was for anyone know ? 3.08 mins on the video is a clear shot.

It was a back up... Just like having two map sensors on some cars.
