Dear friends, I am a layman about engines, but in many places I hear (almost cliché-sounding) slogans that speak of “indestructible” engines. These slogans often fall when talking about old and above all large engines. “Good old V8 engine”. So these typical old amis with abstruse lifting spaces and that however with relatively low PS. Also with the Germans there are some engines that are often depicted as “unchaputtbar”, like about M54 row six, 2,2L S Audrey from BMW. My lay mind sees the following possible commonalities in these engines: 1. No turbocharger, but vacuum cleaner = less auxiliary technology that can run flutes 2. Relatively few hp on a relatively large capacity and material mass = less/less wear of the respective individual components, looser operation (not at the limit), less pressure, less forces that work. When I think of a small 1.4L engine that works with all possible steroids on beyond the 300hp I imagine what hell conditions are in there. Is this possible? Large suction motor with relatively moderate PS = durable and stable?
