Here is a sample picture of an E90 with the same engine as mine:
Either left or right side will be fine. The SC could be mounted horizontally, vertically or in any desired angle as far as the pulley aligns with the crank.
I will start with the mounting brackets, because if I cannot secure the SC in a way that NO belt slippage or damage occurs there will be no sense to continue on.
I have the chance to use the services of a professional water or laser cutter for pretty cheap price. This will assure perfect dimensioning and precise cutting.
