I keep saying that going to a larger pipe will decrease the friction. You say it will increase the friction. Now you say a larger pipe will decrease the Major head loss, but it will increase the minor head loss. Now I'm not sure but to most people major is bigger and more important than minor. So if the OP increases the size of his pipe by one or even two sizes, trying to find the best 90 degree turn will not make any difference since the major friction losses have been decreased.

I'm not the one that stated "You wouldn't think so but larger pipes will actually add more head. Trust me, I'm an engineer." in reference to a large pipe decreasing head.

Maybe you should start paying a little more attention in your fluid dynamics classes.
