The NHRA Technical department hasamended the rule concerning the design of the firewall for Top Alcohol Funny Car vehicles.

The V-shaped firewall (see diagram), which creates a capsule-style bulkhead between the engine and the driver compartment, is an acceptable design for Top Alcohol Funny Car applications only. The V-shaped firewall must be constructed of a minimum .040-inch aluminum.
