I have a question about engines. The other thread about turbos and engines inspired me to create this one. If there were six engines- 2.0 L I-4, I-6, V-6, V-8, Box 4, Box 6, all the same size would they all produce the same power or would some engines produce more due to the configuration? I was thinking the V-8 would create the most but then again because they're the same size the cylinders would shrink, thus limiting the amount of fuel used. Would fuel economy be also affected by these different engines?
Would the same thing happen for diesels as well?
