Yes I understood all that when I watched the video, I just found it interesting to basically spend $50,000 + per engine plus all the R&D just to extend the rpm of the shift points a few hundred plus rpms but I get why though.
Because they want to win races, all sense goes out the window. I recall Darin Morgan saying he charges $12K for the intake manifold for one of these engines, so I would hate to imagine what the cylinder heads cost.
