Dave Eastwood (Gadgetman) - Club Chairman Posted April 16, 2013 Share Posted April 16, 2013 It's an odd thing that big vs little engine debate; my (very basic) understanding of it, is that the efficiencies, as in bhp per litre of an NA engine, just don't scale linearly as the engine size goes up. Thus a highly efficient, I terms of power generation, engine of two litres might be well over 100bhp per litre. Whereas a highly efficient 7 litre engine is considerably less. (It's too late to explain well, but I hop you can see what I mean). So, with our European eyes used to small engines, we just assume the big yank stuff makes poor power considering the shear size. I suppose, our high power per litre car engines perhaps look just as poor to a motorcyclist, with the loony outputs some of the bikes seem to manage!

Norman Verona Posted April 17, 2013 Share Posted April 17, 2013 Dave, the big European engine achieve over 100 bhp per litre. Bugatti, Audi & BMW seem to get there. I've always been a "small" engine fan. It's clever to get a lot out of a little. Not clever to get a lot out of a lot when it's 50% less per litre.
