cool.

 

that has to be the best video anyone has every posted on this board!

 

CompCams did the same setup on their Spintron a while back....we got to see it in a training class while at Comp in Tennessee....it showed some serious bounce/rotation with a double spring however, and then perfect control with a 918 Beehive spring! So their whole propaganda about having enough spring pressure is kind of deceiving....you can over-do it! Very cool video though! Comp's didn't include the valve drop images.

 

looked like mr. wiggles doing the hoola dance...

cool video.

 

I wish I could see fawkin youtube at work... is ther any other way to post it??

 

Cool vid

 

do springs really rotate like that in normal engines??

 

Although it's not ideal...yes, they do rotate in many setups. As do the valves and retainers...and piston rings too while we're making a list

 

that is one helluva sales pitch!!!
