The reason for this is that most 90* NPT elbows are drilled from both sides and have a large step in the corner than restricts flow. See photo below which explains it better than I ever could:

Aeroflow makes full flow fittings in various configurations. I guess others would too but I like them.

What I was referring in my earlier post was the typical 90* NPT elbow. Every one I've ever seen has a step left in the corner from when the elbow is drilled from each end.

You can see from the pic that the bend is much thicker than the standard ones and that's why they flow more.
