John Simister’s supercharged 1959 Morris Mini on the rolling road

Motoring journalist John Simister came in for a rolling road tune on his Shorrock supercharged 1959 850cc Mini. The well known and very early mini has just had its supercharger rebuilt and required setting up. The single SU carburettor required some needle profiling to get it just right and in the end produced an impressive 70bhp (flywheel approximation). That’s 1275 territory from a little 850.
