Do you have a reference for this? I have never seen anything (to my recollection) that counters the work shown in Hucho's book. I am not saying you are wrong (since aerodynamics is often counterintuitive even to the experienced), I just can't think of a reason why a diffuser would make things worse. I would actually think the bigger the back end, the more of a positive effect it would have. Thanks.
