The magnesium and aluminum bells would not sustain a hit of an exploding it was to happen, but these types of racing clutches are not the type that explode.
Their clutches are tested up to 26,000 rpm.

Jerry, maybe that's why your picture is about 30 years old and black and white because these don't really explode anymore like he mentioned?  |
LOL I talked today with a couple of transmission guys and they seem to think that a Mag bell housing is strong enough to hold a exploding clutch I even called Quartermaster to ask if it is stronger then a scattershield

And the Tech said "a mag bell housing is NOT SFI approved but NASCAR does run them up to 11,000 rpm" so take that for what's it worth
