Hi Chuksy
If 15 throats , then 11.6mm wide by 6.5mm height , with the axis of the diffuser vane at ~22 degrees to the tangent should get you somewhere in the ballpark, but you'll need to draw it up to check if you can get those throat sizes whilst still using the 15 vanes at the size vanes you want , you may need to reduce number of vanes or make then thinner . .
I've worked on a mass flow of 1.7 lbs/sec , this is a tad lower than normal for a 91mm comp inducer , but you have a very large hub diameter which will reduce free airflow area .
Cheers John

updates on the diffuser the casting was made with extra longer body that served as mandrill that will be cut off after milling.
