Are they massive blow-off plates on the side of that gigantic manifold ?
I would guess so, rather than lengthening all those bolts holding them 'chargers down!
When i was last at the Pod for the Main Event, having a look through the pits, they seem to have introduced some new shut off system that kills the engine when the burst plate goes. Looks like in consists of a connectors that runs directly in front of it.
