Well seems how they cruise down the road at a constant 8Krpm’s and most of us here don’t, I think your analogy is poor at best.

after owning many V8’s over the years and few small blocks, I would say that pipe diameter is more a matter of what the car is being used for and less about displacement. Most street cars make their usable power at lower rpm’s and smaller pipes aren’t a performance issue. I realize this is a stupid blanket statement (it should be right at home inside this thread), but in general small pipes hurt a race engine and big pipes hurt a street engine. Personally, I like bigger pipes for their acoustical purposes.
