Good video here. |
Damn, that is a good video. And the graphics - wow. Very impressive and I wish them the best, I mean since I won't be getting into any time machines so as to stay in school in mech. eng. and compete head to head with them.
I can't help but wonder though when we're going to read about something going wrong in that setup with valves being sent crashing into pistons. Maybe it has a sort of fail safe to prevent that.
In some ways the cam and valve train as we know it is a big fail safe in that direction.
