Love your post about the engine testing helmut ,, I once had a good chat to the people that were testing the EF-EL ford motors before they came onto production yrs ago (pity they didnt check the head gaskets better :) and couldnt agree more about the rigorous testing and abuse they get on the dyno ,, only thing about car engine though is most have cast iron blocks ,,, bit of a problem with weight i'd imagine . I'd however love to put a big $$$$ bet on for say a rotax 912 and a late model toyota collora engine alloy block ,,same dyno ,same testing , wonder wich one would win ??? I know who i'd put my money on ..
