amazing

 

Wow! Thanks for the movie. That was the coolest I have seen in a long time.

 

is that the one from the bmw engineers?

 

cool

 

I vote for "coolest video I've ever seen" non **** related that is.

 

Awesome video. will be shared with others

 

How did they do that? anyone know?

 

None of the comments revealed anything. I notice that you never see a full cycle - piston doesn't come back into view after the exhaust valve opens. And then it starts over.

 

I also wanted to know how they did it, and was also disappointed it was not a full cycle. Interesting to note, since you see the intake valve open at very beginning, there's no valve overlap. Not very aggressive cams if it's N/A.
