Overhead Cam at 14K RPM
This video shows an operational cutaway of a BMW S1000RR — a 193HP superbike — bumping against its 14,200RPM redline. A cam and valvetrain at 118 cycles per second is an amazing sight (and sound)





High Perfomance valve spring testing 10K RPM
PAC Racing Springs in-house dynamics testing, utilizing a high performance SpinTron tester. This video shows a Nascar style performance dual spring. This spring shows good dynamic behavior even at 10,000 RPMs. The visual analysis is a useful tool to detect dynamic behavior of valvetrain components at extreme engine RPMs.
