I've searched the forum, but cannot find a procedure for removing the supercharger. Does anyone know if one exists?

 

it's quite a job, but not too difficult.
Remove Induction snorkle first.
Remove the thermostat bolts so it's free to move. And the fat pipe.
remove the top plate bolts with the V8 on. Disconnect the pipes to/from intercoolers.
There's two bolts at the front of the s/c to undo, holding it down onto the block.
To the rear there's one bolt, but it's under the throttle body elbow, remove the t/b and use a ratchet socket to get on the troublesome bolt. You may need to remove the elbow first, does the car have an egr valve, this will have to be dropped off too. Thorough soaking in WH40 helps if it's fitted.
Once all this is clear, you can pull the thermostat housing over the nose of the s/c and lift out.

This is a rough how to, if you get stuck give me a shout.
