Ferrari Mondial 8

Building a stage 2 version of our 3.5L 2V CIS injected Mondial engine was always an option. The extra power was needed to overcome the heavier Mondial chassis. The stage 2 modificationss centered around improving the intake port flow. Special oversize intake valves were used in conjuntion with improved porting to raise the CFM by 10%. Another area where an improvement was made involved the camshaft profile choice. CIS injected engines are very sensitive to valve overlap so the duration of the camshafts had to be conservative while still making power. Overall, the result was very good
