Nope, the IMS is essentially unloaded at high revs, centered by centrifugal force and chains in motion. It is most heavily loaded at low revs, start and stop, and gear changes. Over rev causes rod bolts to fail, ring squeeze, valve float and valve/piston contact, and connecting rods sticking out of the case.
