Interesting. Upper and lower pressures, as well as exit temperature, would tell a lot.

I am now thinking "it works well as is, good temps, not great drag penalty, and I think they look ok". Why change it?
Then don't change it. A few knots won't make much difference, given English distances

I'm kidding.

Seriously, not knowing the root problem(s) would bother me. And there is a drag penalty. I'd guess two, maybe three knots. Sound about right?
