It took a while to find the exact specs, but here is what I have found:
The SSHS12 website states that track safety rules apply.
The Atlanta Dragway website states that NHRA safety rules apply.
The NHRA Rulebook is a 300+ page document that is a bit tedious to go though...
So I did a little searching and found this on the Englishtown Dragway's website. They also conform to NHRA regulations. Here is their statement:
ALL POWER ADDER RACERS WITH N0N-OEM/FACTORY POWER ADDERS IE:SUPERCHARGERS,TURBOCHARGERS,OR THE USE OF NITROUS. SECTION 1A,PAGE 65 OF THE 2009 NHRA RULEBOOK READS AS FOLLOWS. "10.00(*6.40 1/8 MILE) AND SLOWER; ALL E.T.NON-OEM SUPERCHARGER,NON-OEM TURBOCHARGED, OR NITROUS-EQUIPPED CARS WITH AN OEM OR .024-INCH STEEL FIREWALL:
JACKET MEETING SFI SPEC 3.2A/1 MANDATORY. " THESE JACKETS ARE AFFORDABLE. THIS RULE WILL BE ENFORCED!
In my experience, if the fire apparrel does not have an SFI label, it will not be acceptable. It doesn't matter what the industrial rating is, they go only by DFI classification. But you could call Atlanta Dragway at (706) 335-2301 or e-mail track manager Mike Savage at
msavage@nhra.com to verify this.
