The twin expenses camshafts were placed within a light alloy cross circulation cyndrical tube head, and also the hemispherical burning chambers utilized 2 shutoffs each cyndrical tube, as well as were utilized to develop the really high compression proportion of 9.9:1.
One option that was used was to minimize the compression proportion from 9.9 to 8.3:1, which reduced power to 100 bhp in this reduced compression variation which was presented in the future.
