Tuesday Tech Question presented by Evans Coolant

Question:

 

What protective clothing will I need for my Ford Lighting truck that has an OEM supercharger?  I think it will run about 10.50 in the ¼-mile.

 

Answer:

 

In the 2019 NHRA Rulebook section 4A, page 9, Protective Clothing it reads “10.00 (*6.40) to 11.49 (*7.35); all E.T. naturally aspirated, OEM supercharged, or OEM turbocharged with a full OEM or .024-inch steel firewall: Jacket meeting SFI Spec 3.2A/1 mandatory.”
