I believe it is just now getting tuned out. No final numbers yet.

It is my car. I was told today that it was 450 RWHP and 380 lb of torque. Apparently, it takes 6-8 months to make a custom belt and so it will be hard to go to a smaller pulley. Sam is going to try to use smaller pulleys before I pick the car up on Saturday, but no guarantees. I had hoped for 650 BHP.

Hmmmmm. That is surprising, but in some ways not. Twin centrifugal SCs do not overcome the low RPM boost problem as easily as twin turbos since the centrifugal SC still needs peak RPM to make peak boost, with a fairly linear boost curve from start to finish. You are making more WTQ at that WHP level than most of the single SC setups out there, and the GTM guys are not done with it yet. Here's hoping they can squeeze a bit more out of it. But, hey, at the end of the day, you still have one of the most unique FI setups out there right now.
