broken crank

Yup, breaks right where Roger Ditchfield says they break, at the radius from the flywheel to the output shaft...He says the radius is too steep and showed me how the HRC crank is less radiused...He states the racers change their cranks every weekend and make 130 rwhp or under while usage of the HRC crank allowed him to make 152 or something RWHP...

There's a hole in it. Of course it will break.
What happened to the rest of the engine?
