If a new technology within a fan drive cluster (e.g. crankshaft mounted) cannot be found in the list the highest power values within that cluster shall be taken. If a new technology cannot be found in any cluster the values of the worst technology at all shall be taken (hydraulic driven constant displacement pump)
