this is soo engine porn, lol!!

thats not slow motion, that is real time captured by using a strobe light so it looks like its slow. u can tell. look at the liquid, the liquid is moving at regular speed.

People yes we get it. The stroboscopic effect. Want a prize?

[aircooledwizard]

I screw my mrs at that speed....

[bob119911]

its so WET!

flyingchicken33 - yes, frickenchicken, you're partially right. What you actually "see" is the spring's displacement divided by the fraction of the camera's shutter in an interval of time. It is able to capture the moment the spring collapses and extends as it is actuated, only at the time the 'strobe' illuminates the scene. Excellent video for annalytical applications though.

@KyleP133 I realize that peak power wasnt the goal of VVT on the L99, but providing decent power along with good low rpm torque which is needed for the auto car. The VVT isnt for fuel economy, the DOD/AFM is.

@Kiiiizle

yeah but they have air canister instead of valve springs

this is more impressive

@flyingchicken33 i gotta disagree with you there. Photostrobic would give you a very low frame rate. The oil is just moving alot faster than you think.

Great video. How about one on desmodromic valve trains?

@schumifan78 I stated clearly about firing order ranging from 1-120. Which means that cylinders will fire in a row,never two or more at same time. Cylinder fires now-and next time after other 119 cylinders are fired. :)

@5ky5tr1d3r It doesn't matter how many cylinders an engine has, each piston goes up and down once per revoloution of the crank shaft, so if the engine has one, eight or 120 cylinders, the valves will all still open and close in each cylinder over the course of two revoloutions of the crank shaft.
