What is the critical speed for our cars? 300 km/h?
Ben the critical speed of the driveline refers to the maximum safe rpms that the drive can sustain.
Factors that determine this are :
the length of the driveline
thickness of the metal wall
diameter of the drivline
construction of the driveline ie, steel , aluminum, carbon fiber
The critical speed of the LS1 Alu driveline is around 8500 rpms.
Hope that was a clear explanation.
