Status of carbon fiber parts in comp class

[Charles Stewart]

I should have re-read my rulebook before asking that question...
Here are some portion of my communication via e-mail with Pat Cvengros, Pacific Division Technical Director:
-Per the 2024 NHRA rulebook page XIX fourth paragraph it reads in part, On the other hand, as to performance equipment, it is the general rule that unless optional performance equipment or performance-related modification is specifically permitted by this Rulebook, it is prohibited.
With that said, the items mentioned (re: internal parts like: piston, rod, rocker) need to be steel or aluminum.
