If you take the larger straw (hardy's for example) and do the same thing, you can't get a steady stream that feels controlled since you are moving less air than the orifice is made for. This can create inefficiency in the intake portion of the system.

That's not proving what you think it is. The reason you can't get a constant flow through the larger straw is because you can't create a consistent lower pressure in your lungs. An engine doesn't have that problem.
