Well. here is the latest.
I made the tube uotlet to be 98mm in diameter amd I cut a slot in the wedge basically removing the rounded lip at the back.
I did this so I could install a sharpedged aluminium wedge from the fromt of the slot to smooth out the air and by being installed from the fromt it can not come loose and go into the fan......then the idea struck me - I will forst run the setup with that "cheater hole" and see what it does.
Maybe the air that can now enter from the slot will fill that low presure at the back of the round wedge , and as a bonus I now have about 25% more inlet area.
If it works I will omit the alluminium sharp wedge or splitter and just put a FOD cover over that hole.
Hope to run the engine after work tomorrow.
