I need help on this scenario. I can pass it at Bronze using SOHC but I can't get any higher. I tried tweaking with Push Rod and DOHC but neither let me pass (either not enough power or economy too low)
Looking at this thread viewtopic.php?f=13&t=966 , it seems like people are easily achieving 3162 cc while mine only can reach 2179 cc max before hitting the size limit. Their size limit is higher too! Was the scenario limitation changed by developers?
