I think it's ONE thread about ONE very stressed race engine and ONE flywheel explosion.
Fact is, flywheel explosions are very rare with the advancements in design from the 60's, when they were considerably more common. Show me ONE thread here on Club Cobra that has a specific example of a typical street Cobra and a flywheel explosion. You MIGHT see a reference to something like an 800 horse monster or a 9 second drag race only car. But even then, flywheel/clutch explosiongs are incredibly rare.
Then again, you could get hit by a bus crossing the street at any given moment in time...
It should also be noted this 800 horse monster was running a STOCK flywheel. Myself, I run an SFI approved Hays wheel, as they should have done!
