DRAG RACING CLASSES

  • Rules for ALL Classes, every car in every class, WITHOUT EXCEPTION, must abide by these rules. These rules are in addition to the class specific rules below:
    • Turbo crossbolts 3” from the turbine wheel (hotside).
      • Vehicles with STOCK LOCATION turbos and FULL length exhausts, exiting the factory location are STRONGLY encouraged to have crossbolts – this will be a requirement for TX2K26
      • Vehicles with aftermarket turbo locations or added turbos require crossbolts – for safety they are mandatory. If they are not visible during inspection a photo must be available during tech.
    • Engine pan OR engine diaper mandatory on all cars – diaper must provide full engine coverage, pan must have at least 2″ lip AND a liquid absorbent pad at bottom of pan.  Note some classes have more specific restrictions listed below.
    • No coolant allowed, water only, no water wetter allowed. This includes cooling systems and “interchillers”. If your car leaks coolant on the track, you will be removed from the event and potentially banned from future TX2K events.
    • Tires sizes are always checked by sidewall designation, and not by measurements posted on the tire manufacturer’s website.
    • If your car has a parachute – the pin MUST be pulled prior to you staging on EVERY pass.

Please note that ALL safety rules are for both our fan and racer safety. Our intent is NOT to make it difficult or complicated to compete and have fun at TX2K. If you have questions, need clarification or to request an exception, please reach out to peter via email @ [email protected]
