I can count six belt driven pulleys, including an interesting one in the shape of an air suspension compressor, yet I can also spot the hydraulic pump as used on the hydraulically suspended Ch. 116 and Ch. 126 models. Which one was he using - also, what was the method of feeding oil to the air suspension compressor. A very gifted engineer, an overly complex project. Incidentally, an Australian M100 (6.9) engine runs a compression of 8.00:1 - surely even that ratio could be a bit high for a turbo installation.
