"40lbft is a hell of a lot for an M8 fastener"
OK give it 25 or 30 ft lb, the point I was trying to make is that it is not loaded in addition to the clamping force it is giving to the cover to the flywheel and the actual torque is a bit academic provided it is sufficient keep the pressure plate in constant firm contact with the flywheel. As has been pointed out the standard torque is 20 ft lb, anything over that will be more than enough provided all the torque is transfered to the cover. My reason for recommending something higher is that at 20 ft lb the friction of the threads can leave you a little uncertain how much load is clamping the cover especially if using locktite as you have to have it free of other lubricant.
Yes Tom I was wondering if you were aware of how fierce the action of one of these can be, Having driven a couple they can be a bit "dead" and the transition from bighting to fully in just happens, they are a pig to get to slip like you would a normal clutch. They are good once you get used to them, especially as they are quick in action when changing gear, you really can't over slip them and soften them with a hard start (well you can but you have to work at cooking them) they are just different just give yourself a little extra room the first time you drive with it in traffic
Best regards
