When I bought my new 95TT, Brett Ramey of RameyZ fame practically game me his/TwinTurboPete's old Pentroof/ TD06-20G / HKS external wastegate setup. I know Brett put down something like 667WHP with the setup (it's on youtube somewhere). I just don't see myself spending the money to build a wild motor that would take use of these (I would want something that could rev up well over 8000-8500 RPM to maximize the area under the power curve).
Rule #1 - There's always a bastard!
