Ingvar Malm confirmed that he has experience of both a gear drop-box and a chain drop-box in his Elva 100. He says that the box with the chain does not run any hotter than the one with gears. Rather the opposite. He is using a normal hypoid oil in both types of box, i.e. something around SAE90. One thing he has done, though, is to make sure that there is a good flow of air around the drop-box. He has a scoop to get air in and has hole to let it escape. Before he did this, it was running too hot (both the gear type and the chain type).
