Interesting - I always thought this wouldn't work because the wastegate flow was restrictive... it wouldn't be able to bleed enough boost at higher rpms/air flow rates. If somebody's figured out a solution to this, I'm really surprised this isn't getting more air time, it would solve a lot of the 'issues' (if you can call them that) with centrifugal SC's.
