Seems like this was a photoshop.
When it first was created was for the 'gap filler on a T-100 with trailer' thread. (Yes I butchered the title)
Increasing the frontal area will negate the aero gains.
Again, the fairing and the rear Kamm should help. Same as NASA's rig.

I can't understand why my MPG's are so low..........
