valve spring motion

Post by bsfc9 »

a couple of years ago at PRI i saw some high speed photography of valve spring motion and i must say it was unbelievable. the amount of spring surge and seperation from the retainer and spring seat was crazy :shock: . i would like to view something like this again. has anyone found anything like this on the web or available anywhere else? thanks.
