Frank and Jim,
I am sorry that I never got a chance to reply witht he specific on the turbo. I don't even remember the specs on it. This was a franken turbo created for me by Turbo Specialties. There were only few created and I was lucky enough to own one of them.
Jr should have laid your dyno chart on top of mine (when I dynoed the 16G). and see if the curves were any different. It spooled for me like a VF30 would but felt much stronger on top end.
There is def. somepower left in it. My STi injectors were just maxed out.
Throw some race fuel and see where it goes.
