It rattled with the single row timing chain as well and when I installed the double row I installed two gaskets because of the clearance issues.

Thanks mate.

So does the rattle goes away with the blower disconnected?

Probably coupling in the SC or something in the SC.


I would try revving it with the SC bypass valve manually opened and see if it still makes noise. That will still let the SC run but without load on it.

I tried another complete supercharger with a new coupler and the rattle is still there.
