I was looking for this video, just found it again. A bone-stock RX-8 at Lagnua Seca. When I talked about keeping the engine above 5 grand, and the red line beep, you can see both demonstrated here.
Pay close attention to after the 1:40 mark, as he crests the blind hill, and enters a series of downhill corners. That's what makes Lagnuna my favorite track.
