If you think about it there is no reason to design a hub to slip timing.
This will not save your engine from damage in any way whatsoever.
The new M engines don't have this design anymore because it's an unforeseen weakness.

I had crossed virtual paths with an M4 engineer on the internet a few months ago and I asked him why they made the exhaust unequal length.
He said something to the effect of "thats what gives it the aggressive sound!"
Funny, they wanted it to sound this way.
Anyway that's unrelated and an ADD moment.


It's not a fuse, it doesn't protect anything. Any time the hub slips it is an expensive venture. I can't recall one instance of anybody saying they were happy their hub slipped because it avoided damage.
it makes zero sense.

Most SCH simply result in having to retime the valvetrain. However, some presumed "fixes" have resulted in catastrophic failures. Go figure...

Anyhow, I could be wrong about the fuse aspect, it is something I recall from all the discussions. In the end, on a stock tune, I have zero worries about a SCH.
