Wilf: You hit the nail on the head! If you're not going to turn your engine over 6K and it's backed up with a steel, nodular-iron or aluminum flywheel, there's no need for a scattershield providing the flywheel and clutch are in good shape. As for me, I have a small block that twists the tach to 8,000 rpm, so I feel safer with a blow-proof bellhousing.

Having done expert witnessing for some massive clutch explosions and the resulting injuries, I can testify to the damage that can be done . . . lost limbs, a pierced lung . . . not pretty stuff. Damage to the car becomes secondary in such cases. I once had a case when a top fueler was cut in half when the slidder clutch went through the "blow-proof" bellhousing. A fan in the stands was injured! Such damage wouldn't happen with a Cobra, but it would still be like a hand grenade exploding under the floor board. So if you're in doubt, protect yourself first, then the car.

The tought about wrapping the bellhousing with a ballistic blanket is a good thought, but I wonder if they would contain a serious flywheel/clutch explosion. Worth contacting manufacturers for their comments, though.
