BIR implemented an oil down policy midseason 2023. This rule will be in effect for 2024. 

Oil Down Policy 

  • Test & Tune (TNT) Tech Cards for Weekend 

  • First oil down: no penalty 

  • Second oil down: loss of TNT tech card for that day. If racer wants to buy another TNT card for the same weekend, payment of $250.00 cash penalty to the race director is required prior to the purchase of a new TNT card.

  • Third oil down: Tech card will become void and no additional tech cards can be purchased for that weekend or event.

  • Event Tech Cards 

  • First oil down: no penalty 

  • Second oil down: $250.00 penalty will be paid to the race director to be eligible to continue racing that event.

  • Third oil down: disqualification from the current event (All tech cards will be void with no refunds)

Note: this applies to any event on the drag strip, including but not limited to, each Muscle Car series event (Street Car Showdown, Show N Go, Muscle Car Shootout), Bracket Race (per race day as each is a separate event), or Karmageddon. 

An “clean-up” is defined as any incident requiring the use of mechanical equipment (i.e., tractor, truck, tenant, sweeper, etc.) to clean up fluids (e.g., engine oil, gear oil, anti-freeze, transmission fluid, etc.) deposited on the track by a race vehicle (car, dragster, bike, sled, etc.). Spills or drops of fluids cleaned up by hand are not considered violations and penalties will not apply. On occasion, equipment will be used to touch up the racing surface. Such maintenance is not considered a clean-up. This policy encompasses the entire length of the “track surface”, including but not limited to the staging lanes, burnout box, starting line, racing surface and the shutdown area to the point the vehicle exits (including the turnout area if clean-up results in a delay of the race). 

The removal of objects such as blower belts or miscellaneous parts from the track surface does not constitute an “clean up”. It also does not apply to fuel, fire extinguishing systems, drive line parts (not including fluids), wheels, tires, brake systems, etc.  An oil/liquid cleanup resulting from a crash will not result in a penalty unless the accident was a result of depositing oil/liquids on the track.                                                            

  • BIR requires all cars running faster than 9.99 in the quarter mile, 6.39 in the 1/8th mile or 135 mph and faster to have a NHRA-accepted lower engine oil–retention device (diaper); A belly pan may used in lieu of a device attached to the engine. If a belly pan is used, it must extend from frame rail to frame rail and extend forward of the harmonic balancer and rearward to rear engine plate incorporating a minimum 2” lip on all sides. A non-flammable, oil-absorbent liner mandatory inside of retention device.

  • Use of engine oil containment device is highly recommended in all vehicles

“What does the orange cone on the starting line mean?”  

If your vehicle has street tires, you will be “coned” when you pull up to the starting line. This means that you must keep your wheels aligned with the orange cone and out the of the “groove” on the racing surface when you’re making your pass down the track. Street tires tear up the surface rubber and we want to that groove for vehicles running drag slicks/radial tires.
