I made new mounting brackets for the handbrake calipers that move the caliper a little higher so the cable runs a little more like original. Also I got cast metal guide wheels instead of the plastic ones.
I found a drive pulley for the supercharger. It is from a 540-740-840 BMW and has 7 grooves, the SC has a pulley with 8 grooves but I couldn't find an 8 groove pulley.
Then I had to design an adapter to mount the pulley to the crank harmonic balancer.
A local machinist made it for me, he changed the design a little to ease manufacturing. I will fit dowel pins at the crank side to prevent slipping.
I thought I might get the BMW idler pulley as well, fair price at 10 Euro.
And ordered a 7 rib belt of correct length.
