ET Specs For NHRA


I have a street car. What do I need to come out and test or race?

The basic items needed to pass tech inspection for the typical street car include good tires, a battery tie-down, radiator overflow catch-can, operable neutral-safety switch, seat belts, and a valid state driver's license or NHRA competition license is required for all participants. Donít forget to wear long pants, shoes, and a shirt!

What do I need to race my street bike?

Again, a valid state driver's license or NHRA competition license is required. NHRA approved helmet, denim or heavier pants, a leather jacket, leather gloves, and leather shoes that rise above the ankle. If the bike runs quicker than 10.99 or faster than 120 mph, additional requirements apply.

Do I need a helmet?

A helmet is one of the first safety items that you may need to purchase. Any vehicle that runs faster than 13.99 seconds, and all motorcycles and dune buggy-type cars, must have an approved helmet. Helmets must have a SNELL rating of 95, K98, 2000 or 2005, as well as those with an SFI rating of 31.1, 31.2, 41.1, or 41.2. SNELL 95 helmets expire 1/1/2007.

Can I use nitrous oxide?

NHRA allows the use of nitrous oxide in bracket classes. Check the track's specific class rules to be certain, but in most cases you can use nitrous. Nitrous bottles must be vented to outside the driver compartment if it is mounted in the same compartment as the driver. All bottles must be stamped with a DOT Ė 1800 pound rating.
